The Cherry Hill Arts & Music Waterfront Festival was postponed to a later day. Though, organizers continued on with their drone show delay.

The Pier Six Pavilion show was also canceled, while the Pratt Street Market @ Night as well as the Fireworks show at the Inner Harbor were delayed due to the storm.

Celebrations go on

Despite triple-digit heat and a severe thunderstorm, Baltimore found a way to party and enjoy the 4th.

"We just came from eating," said Shenise Jackson, who came to the Inner Harbor for the fireworks.

Many tried to spend most of the day out of the sun. If they were outside, they cooled off as much as they could.

"Went to work," Ann Lacy said. "Air conditioning and everything."

"We came [out] later in the day and had ice cream," Katie Lalande said. "We played in the water."

Many waited patiently for what they call the best part of Independence Day.

"Everybody at one place," Marco Blackwell said. "They're watching the fireworks."

"I come here every year," Lacy said before enjoying the Inner Harbor fireworks show. "I love it."

"We haven't been down to the harbor since he was a baby," Jackson said. "So, that was like 10 years ago. So, I'm looking forward to seeing the fireworks."

Although it went on later than expected, the fireworks did not disappoint the crowd at the Inner Harbor.

It capped off a night where many were reminded of years of history and what Independence Day means to them.

"Hanging out with family," Chyne Jackson said.

"Our country has been going through a lot the past however many years, and it's just time to come together…and just to celebrate our freedoms that we do have," Lalande said.

Light Rail services suspended

Meanwhile, the Light Rail suspended service at all stations south of Patapsco after power lines and trees were downed during severe thunderstorms moving through the region.

The Maryland Transportation Administration said shuttle service will be available for the following stations up until the storm damage is removed:

• Glen Burnie/Cromwell
• Ferndale
• BWI Airport
• BWI Business District
• Lithicum
• North Lithicum
• Nursery Road
• Baltimore Highlands

Riders should expect longer than usual travel times if they plan to take the Light Rail from Glen Burnie or BWI to Baltimore.

Units say they were dispatched to the 1631 block of Filbert Street for reports of a fire at 8:00 p.m.

When they arrived, they witnessed smoke from the first and second floors of the Sherwin-Williams Automotive Finishes warehouse in the Curtis Bay Industrial area.

The incident was made a working fire and then rose to a fourth alarm in order to bring in additional resources, the department said.

Baltimore Fire Department posted a video to X and Facebook Reels, showing responders putting the fire out.

No injuries were reported. 

The cause of the fire remains under investigation.

Gunnar Henderson extended his hitting streak to 10 games with a single on the first pitch of the game, Pete Alonso walked, and Basallo hit his 14th home run of the season. 

The Reds pulled ahead 4-3 with a three-run second inning. Jose Trevino doubled home Spencer Steer, TJ Friedl followed with a triple to tie the game, and Elly De La Cruz put the Reds in the lead with a single against Brandon Young (7-2). 

But the Orioles scored five times against Greene in the fourth. Adley Rutschman hit his second double of the game to drive in two runs and scored on Alonso's second hit. 

Greene (0-1), returning after surgery to remove bone chips from his elbow in March, lasted 3 1/3 innings, allowing eight runs, which ties a career-high, on seven hits. He walked four and struck out seven. 

Young, who has won four of his last five decisions, allowed four runs on eight hits and three walks in five innings. He struck out five.
He gave up a walk to Steer and Trevino's third hit to start the sixth, but Grant Wolfram relieved and induced a double play from Friedl to escape the inning. 

Rhett Lowder, who was moved to the bullpen when Greene was added to the rotation, pitched three scoreless innings. 

Tyler Wells pitched the ninth for his second save. 

Chase Burns and Sal Stewart were named to the National League All-Star team. Stewart joins Frank Robinson, Johnny Bench, Chris Sabo and Scott Williamson as the only Reds rookies to be named All-Stars. 

Up next
Kyle Brandish (5-8, 3.77 ERA) pitches for the Orioles, Nick Lodolo (2-2, 5.05 ERA) starts for the Reds on Sunday.

A representative for Swift confirmed in a statement provided to CBS News that the two were married in a ceremony officiated by comedian Adam Sandler. He was described by the representative as a "friend" of the couple. 

The couple had no bridesmaids or groomsmen. Swift's brother, Austin Swift, served as her "Man of Honor," the representative said, while Kelce's brother, retired NFL offensive lineman Jason Kelce, served as Kelce's best man. 

According to Swift's representative, her wedding dress was created by Christian Dior Haute Couture.   

In a now deleted X post, AMC CEO Adam Aron, one of the guests, shared that the couple transformed the venue into a "secret garden," complete with large photos of Swift and Kelce at every age.

The vows the bride and groom wrote were "emotional" and "charming," Aron said.

Camera crews caught Robin Gentry, Swift's aunt leaving the venue last night.

"They cried, and they laughed and they danced, and they hugged and they kissed," Gentry said.

Social media posts showed peach-colored carpet and drapes, and a party favor with the lyrics from the Swift song "Blank Space," "So it's gonna be forever."

A jumbotron outside Madison Square Garden lit up with the words, "JUST&T MARRIED!" following the news. The Empire State Building also announced on social media that it had lit up in "something blue" in celebration of the wedding. 

The couple welcomed around 1,000 guests at Madison Square Garden to celebrate their marriage, according to law enforcement sources familiar with the security planning. It was not immediately clear if the wedding ceremony occurred at Madison Square Garden, or at some point before. 

Large black SUVs were seen starting to arrive at the famous venue shortly after 3 p.m. ET, pulling into white tents set up outside. The plans included a cocktail hour, ceremony and then a reception, with the celebration expected to stretch into the early hours Saturday, the sources told CBS News. 

A large crowd of onlookers and fans lined the streets near the arena, holding signs of support and hoping to catch a glimpse of those attending the wedding. Some of the guests spotted arriving included actors Hugh Grant, Jason Sudeikis and Ethan Hawke, soccer star Abby Wambach, sports broadcaster Joe Buck, musician Benson Boone, NFL star Cooper Kupp, and Paulina Gretzky, daughter of hockey legend Wayne Gretzky. 

A rehearsal dinner was held at MSG Thursday, with about 100 family and friends on the guest list. Some of Swift's friends, including Lena Dunham and her childhood friend, Abigail Anderson Berard, were spotted arriving for the dinner, USA Today Taylor Swift reporter Bryan West told "CBS Mornings" Friday.

Both private security and the New York City Police Department were in place at Madison Square Garden. There are 135 officers assigned around the venue Friday, law enforcement sources said.

Streets directly around MSG were closed, and there were police barricades blocking pedestrians from camping out on the sidewalks nearby. 

The event featured musical entertainment, and crews built a massive set inside the arena for the occasion.

"This is going to be an absolute, spectacular blowout," People magazine editor-in-chief Charlotte Triggs told "CBS Mornings." "According to a source, it doesn't look at all the same inside. They've completely transformed it." 

Details from inside the venue were hard to come by. But reporters had been watching for days as a parade of 18-wheelers delivered and unloaded supplies, mostly under wraps. 

It was safe to assume the famed basketball arena and concert venue was decked out for a one-of-a-kind celebration, celebrity event planners told CBS News, with one comparing the process to producing a "blockbuster movie."

West predicted there would be a bucolic garden theme. Watching as things were unloaded, West said he saw a bar stretcher labeled "trees."

"So I'm picturing kind of like a forest or a garden," he said.

Triggs said Swift's familiarity with Madison Square Garden made it an appealing option for the couple.

"I think for most people, this seems like the weirdest choice in the world, but for her, this is spot-on. It has total security. Also keep in mind, she's very familiar with it. She performed there multiple times," Triggs said.

The extravagant affair came three years after Kelce attended one of Swift's Eras Tour shows in Kansas City — and called her out on his podcast after he didn't get to meet her. 

Taylor Swift and Travis Kelce's relationship history

The Kansas City Chiefs tight end shared his disappointment about not meeting Swift on "New Heights," the podcast he does with his brother, former Philadelphia Eagles star Jason Kelce.

"I was a little butthurt I didn't get to hand her one of the bracelets I made for her," he said, explaining he had a friendship bracelet with his phone number on it to give her. 

That clip made it to Swift's mom, Andrea, who would encourage her to meet Kelce. Swift was initially hesitant about dating an athlete, she said in the "Taylor Swift: The End of an Era" docuseries, thinking she wouldn't know what to talk about.

But she soon learned she had plenty in common with Kelce. 

"It's shocking how many similarities we have towards our jobs and how we view them, and how we view each other," Swift said in episode 4 of the docuseries. "We both have jobs where we go out in NFL stadiums and we entertain people for three and a half hours — his with considerably more violence than mine, but he's not in heels."

Swift said that while she had trouble maintaining a relationship in the past during a tour, she didn't have that problem with Kelce. 

Each of their passions "fuel each other," she said. "Ultimately, we love cheering each other on."

Fans took notice as Swift showed up to cheer Kelce on at NFL games, including the Super Bowl, and as Kelce attended several Eras Tour concerts, even making a surprise appearance on stage at a June 2024 show in London.

The duo announced their engagement last August in a joint Instagram post captioned: "Your English teacher and your gym teacher are getting married."

In another clip from the docuseries, Swift described how she couldn't have imagined the way her relationship began with Kelce. 

"If you ever would have told me that the most meaningful relationship I would ever have would start with a man saying that he was butthurt that I didn't want to meet him, like, unbelievable," she said.

What's next after Taylor Swift and Travis Kelce's wedding? 

Swift and Kelce haven't shared a honeymoon destination or other post-wedding plans, but Britney Spanos, a journalist and professor at New York University who teaches a course about the pop star, said she thinks "there's probably new music on the way." 

"If we know anything about Taylor, especially the last six years of her career, she's constantly writing," Spanos told "CBS Saturday Morning." Spanos speculated that any new music could focus on Swift's life and relationship, giving fans "glimpses within the private life of her and Travis." 

The couple may also "continue to combine their powers," Spanos said. 

"What they have aimed to do so far is to find ways to meet each other in the middle between football and pop music," Spanos said. "So, I think we're going to keep seeing ways they're going to integrate each other into their lives." 

Widespread rain and storms have also prompted Sunday, Monday and Tuesday First Alert Weather Days as well.

Strong storms bring relief from the historic heat in Baltimore

After enduring days with afternoon temperatures near 100° and heat indices above 110°, today marks one of the hottest July 4ths in recent memory.

BWI reached a high temperature of 102°  - a new record for the date. The airport also clocked a 58 MPH wind gust as severe storms moved through. The worst of the storms have moved into Delaware. The risk of severe weather continues to steadily drop. However, lingering scattered showers and occasional lightning will continue in a few spots late into the evening. 

Stormier weather pattern is developing across Maryland

The chance of heavy rain and a few severe thunderstorms increases further on Sunday.

After a mostly dry and muggy morning, more storms are forecast to develop as temperatures soar into the 90s. First Alert Weather Days will continue on Monday and Tuesday, due to the risk of more strong storms. The risk of flooding is a bit greater on Monday and Tuesday as storms will be slower moving.

Temperatures will warm into the upper 80s and lower 90s each afternoon next week. The forecast calms down by mid-week, ahead of more storms by the end of the workweek.

The Maryland State Fire Marshall made the announcement shortly before 7 p.m. on Saturday, stating they were actively investigating the incident.

First responders were alerted to a reported boat explosion around 4:20 p.m. at Schaefer's Canal House, a seafood restaurant located in Chesapeake City.

Officials have confirmed that nine people were injured. Seven of them were on the boat when the explosion occurred, and two were on a nearby dock, according to the Maryland State Fire Marshall.

Four people were flown to hospitals by Maryland State Police and Christiana Care Health. The three others were taken to local facilities via ground transport.

The Maryland State Fire Marshall will provide updates on the situation as they become available.

U.S. Transportation Secretary Sean P. Duffy made the announcement that 46 states would receive investments to rehabilitate and upgrade their airports ahead of the Fourth of July holiday weekend.

"What better way to celebrate America than investing in its future," Duffy said in a statement issued by the U.S. Department of Transportation. "We're ushering in the Golden Age of Transportation and rebuilding our airport infrastructure is critical to making that vision a reality."

According to the U.S. DOT, BWI Airport was awarded $62.4 million for runway and runway lighting rehabilitation. 

"The FAA is prioritizing improving our nation's airports and ensuring we issue grants quickly and efficiently," said FAA Administrator Bryan Bedford. "This funding does more than just rebuild runways and taxiways; it modernizes the travel experience for American families, ensuring our airports are safe and ready for the future."

Other major airports, including JFK and Orlando International Airports, received infrastructure investments for tarmac rehabilitation, terminal upgrades, and better visual guidance lights.

In 2025, BWI received $41.5 million from the state's Board of Public Works for security checkpoint and baggage system upgrades.

BWI has frequently been ranked among the top airports in the country. In 2026, it was named the 10th best airport in the U.S. in an annual survey conducted by AirHelp, an air passenger rights service. 

The concert was scheduled to take place at Oregon Ridge Park in Cockeysville at 8 p.m.

According to the BSO's communications team, ticket purchasers may either exchange their tickets for another summer performance or receive credit towards a future concert. Patrons may also donate their tickets back to the BSO to provide critical operational support.

The value of the tickets, along with any pre-purchased parking costs, has been placed back on buyers' BSO accounts and may be used through June 2027.

"We apologize for any inconvenience this may cause, and we are sorry to miss sharing in a second evening of music and community together in celebration of the holiday and Maryland 250," the BSO wrote in an announcement posted to their website. "All tickets will automatically be converted to an account credit. We appreciate your continued support and invite you to use this credit for one of our upcoming BSO events."

Severe thunderstorm watch in effect

The entire Baltimore metro and much of Maryland is under a Severe Thunderstorm Watch until 10 p.m. 

Scattered thunderstorms with wind gusts up to 75 mph, heavy rain, and lightning are forecasted Saturday evening. 

Stay up to date on the latest forecast with WJZ's First Alert Weather team.

BGE Spokesperson Nick Alexopulos said the outages in Baltimore were caused by underground cable faults.

"From wear and tear that is expedited by extreme use and extreme heat," he said. 

At least 116 active outages were reported around 10:20 a.m. That number fell to 102 around 2:11 p.m., with 586 customers affected.

Alexopulos said, thankfully, outages were low, though he understands how this can be a headache for anyone trying to beat the heat.

"It is unbelievably frustrating when it's this hot outside to lose power for even one minute," Alexopulos said.

Because of this, BGE has increased staffing this weekend to restore power and respond to any other potential incidents. 

BGE's tips to beat the heat

Alexopulos said BGE continues to advise its customers to practice specific tips to prepare their homes for extreme heat and to alleviate stress on the power grid.

"Raise their thermostat to a higher temperature that is comfortable for them," he said. "78 may be too hot for you, but 78 is a target number."

Close blinds, shades and drapes during the day. Also, maintain A/C systems by having units serviced and cleaned.

Avoid placing lamps or TV sets near thermostats. Thermostats sense heat from these appliances, which can cause air conditioners to run longer than necessary.

BGE also asks customers to report any outages.

Baltimore residents impacted by power outage

Essex neighbor Bob Freund noticed the power inside his home went out just after 2 a.m. Friday.

"I got up 6 o'clock, strolled outside, drug the generator over, plugged two lines in," he said.

Freund said he was able to connect his refrigerators to the generator. He even helped out one of his neighbors who was also experiencing an outage.

"It's starting to get warm inside the house now," said Essex neighbor Bob Freund. "So, it came back on at the right time."

BGE crews could be seen on East Pratt Street near Collington Avenue working to restore power as quickly as possible.

According to Baltimore Police, the incident happened just before 11:30 p.m. Thursday night.

When officers responded to the crash, they found the 20-year-old man injured and transported him to a nearby hospital to receive treatment. He was later pronounced dead.

A preliminary investigation was conducted, revealing that police officers initiated a traffic stop for two mopeds at the 100 block of Eutaw Street. 

One of the moped drivers stopped. The other fled, later ejecting from the vehicle after crashing it into a brick wall located on the 600 block of West Franklin Street.

Crash Team investigators responded to the scene and took control of the investigation. Police are asking anyone with information to contact them at 410-396-2606.

Those who'd like to remain anonymous may call the Metro Crime Stoppers tip line at 1-866-7LOCKUP.

The Orioles executed a double steal in the first inning and Gunnar Henderson scored when the throw to third base from Reds catcher Tyler Stephenson sailed into left field for an error. 

Basallo's 13th homer came off starter Brady Singer to make it 3-0 in the third. 

It was the 20th home run allowed by Singer in 17 starts this season, surpassing the 19 homers he gave up last year in 32 starts.
Rogers (6-7) limited Cincinnati to two hits and struck out four. But he matched a career high with five walks, a total he also reached May 4 against the New York Yankees. 

Rico Garcia tossed two innings and Yennier Cano worked the eighth. With reliever Ryan Helsley placed on the injured list before the game, Tyler Wells pitched the ninth to finish the four-hitter. 

It was the first save for Wells since Sept. 28, 2023, against the Boston Red Sox to clinch the AL East title.
Singer (3-8) permitted three runs - two earned - and three hits in five innings. He struck out six and also tied a career high with five walks. 

The previous time Singer issued five walks was July 13, 2022, against the Detroit Tigers.
Reds shortstop Elly De La Cruz, 24, got his 150th career stolen base in the third inning to become the youngest Reds player (since 1900) to reach that mark since Eric Davis at age 25.

Up next 

Reds RHP Hunter Greene comes off the injured list to make his season debut Saturday night. RHP Brandon Young (6-2, 3.11 ERA) goes for the Orioles.

The heat wave sweeping the eastern U.S. was expected to peak Friday and Saturday, forecasters said, as dangerously high temperatures continued to ramp up from the Midwest to the East Coast. Between daily high temperatures and warm overnight lows — which won't be low enough to offer much relief — more than 300 records are expected to be set by Saturday.

More than 185 million people were under heat alerts Friday, including residents of multiple major metropolitan areas, like Boston, New York City, Philadelphia and Washington, D.C., according to the National Weather Service, which has issued a mix of "extreme heat" warnings and heat advisories for dozens of states. The weather service said peak heat indexes, which account for temperature and humidity, could soar to 115 degrees in some places.

High temperatures were already impacting holiday celebrations on Friday, as safety concerns prompted some event organizers to postpone or cancel plans. Amtrak also canceled some Northeast trains because of the potential effects of excessive heat on its tracks.

Heat wave forecast maps

Zoom in on any location on the map below, or search for your city or town by name, to see the forecast high temperatures, how hot it will feel, and the overnight lows for each date.

"These are extremely dangerous conditions," New York City Mayor Zohran Mamdani warned the city of over 8 million residents. On Thursday, the city tied the record high temperature of 100 degrees set on the same date in 1966. It could hit triple digits again Friday, with the heat index even higher.

An extreme heat warning is in effect in the city until 9 p.m. ET on Saturday.

For the first time, New York City is deploying vans staffed with nurses and paramedics who will hand out water, electrolytes and sunscreen, CBS News New York reported. They will also perform wellness checks, transport people to cooling centers and make in-home visits to vulnerable residents. The city is also opening cooling centers throughout the five boroughs.

"My recommendation to all New Yorkers is to stay inside and stay cool," Mamdani said, "and if you happen to be getting married at Madison Square Garden, you will be staying inside and you will be staying cool, and I think it's a good example to set for the city at large." Mamdani was referring, of course, to the Taylor Swift-Travis Kelce wedding that sources say is set for Friday night.

With more than 100 record highs and more than 200 record warm overnight lows expected through Saturday evening, some spots could shatter records that are more than a century old, according to CBS News meteorologist Nikki Nolan. Temperatures will be 20 to 30 degrees above average.

Ten states will have temperatures above 100 degrees on Friday, Nolan said.

In Philadelphia, where organizers canceled plans for Friday's Salute to Independence parade due to the heat, an extreme heat warning is in effect until 8 p.m. Saturday.

Boston hit 100 degrees for the 29th time in its recorded history, setting a new daily high temperature record, on Thursday. There's an extreme heat warning in the city in effect until 8 p.m. Saturday.

An extreme heat warning Friday for Washington, D.C., will also be in effect for the capital on July Fourth. A high of 102 is expected on the holiday, which would top the city's highest recorded temperature for that date, 100 degrees, set in 1919.  

The organizers of Washington, D.C.'s Independence Day parade canceled Saturday's 10:30 a.m. event due to the extreme heat. 

The Great American State Fair, taking place on the National Mall, shut down in the early afternoon Friday but reopened at 5 p.m., organizers said. Fireworks displays were canceled or postponed in several of the surrounding suburbs because of the heat.

D.C. Mayor Muriel Bowser urged residents and visitors to plan ahead, stay in the shade and limit time outdoors as D.C. plans to mark the nation's 250th birthday with all-day festivities and more fireworks than previous years.

"This is your friendly reminder that the sun is not playing around," the National Park Service said in a post on social media. "As always, we encourage everyone heading outdoors to stay hydrated, take breaks in the shade, wear a hat and sunscreen, sploot responsibly, know your limits, and look out for one another."

Freedom 250, the organizer of the "Salute to America 250 Celebration & Fireworks" taking place Saturday on the National Mall, said that it was adjusting the timing of the events because of the heat. 

"In light of current heat conditions, Freedom 250, United States Park Police, National Park Service, the United States Secret Service, and the Federal Emergency Management Agency have coordinated closely to adjust event timing and expand cooling resources, water stations, and medical support across the grounds," organizers said in a statement Friday. 

Severe storms that have been making their way from the Plains to the Northeast will shift southward, bringing a risk of storms to the I-95 corridor, from Virginia to New York, over the Fourth of July weekend.

In the West, dry conditions and high winds have fueled destructive wildfires in parts of Utah and southern Colorado. Red flag warnings were in effect through Friday, with forecasters warning of wind gusts up to 45 mph and relative humidity down to 7%-12%.

Health hazards of a heat dome

The sweltering conditions are part of what's known as a heat dome, a large area of trapped heat under very strong high pressure. The combination of heat and high humidity feels insufferable and dangerous because the human body can't cool off as effectively when sweat stays on the skin. 

Heat is the leading cause of weather-related deaths, and is especially hazardous for the elderly. During last week's heat wave in Europe, more than 1,300 additional deaths were reported.

Warning signs to look for to prevent heat-related health emergencies include fatigue, light-headedness, muscle cramps and upset stomach. If anyone exposed to the sun is experiencing such symptoms, doctors say they could be suffering from heat exhaustion.

"For heat stroke, the differential factor is that altered mental status, that confusion," Dr. Catrina Cropano, the medical director of the emergency department at New York City's Mount Sinai West, told CBS News. "If you are experiencing any symptoms of heat stroke, you really need to make sure you come into the emergency department as quickly as possible."

A boy who was participating in a pregame ceremony for Minnesota's St. Paul Saints on Tuesday started to faint on the field after he had been in the sun all day, a spokesperson for the minor league baseball club told CBS News on Wednesday. A video posted on social media showed outfielder Walker Jenkins carrying the boy off the field.

"Walker as you saw in the video grabbed him, rushed him over to our dugout and handed him over to our Athletic Trainer, Chase Thompson. Chase brought him into our training room, gave him Gatorade, ice packs, took his blood pressure and pulse and had the EMT's on site check him out," St. Paul Saints spokesperson Sean Aronson said.

The boy went home with his family and "is doing fine," Aronson said.

Children are more vulnerable to heat-related emergencies because they have higher core temperatures, higher heart rates and lower sweat rates, especially when exposed to heat.

The feel-like temperature at the Inner Harbor was about 115 degrees on Friday, with heat seen radiating off the pavement. 

"We are asking our residents to take precautions to check on neighbors, and we also push some of the start times of our events back," Faith Leach, Baltimore City Chief Administrative Officer, said. 

Fourth of July fireworks are still on in Baltimore amid the brutal heat wave. 

The city says it pushed back the start time for the Cherry Hill Music Festival and Drone Show. Performances at Pier 6 will start at 7 p.m., and the fireworks will kick off at 9:30 p.m. 

Cooling stations and buses available

With events all day long – including the Pratt Street Market – the city says cooling stations and cooling buses will be available. 

"We also will have cooling stations and misting stations and water that will be available to folks who are out here enjoying the Fourth of July festivities," Leach said. 

Meanwhile, the city is warning neighbors, advising them not to set off their own fireworks. 

"We are asking you to not use illegal fireworks in your neighborhoods, because those can cause fires, especially during heat waves like the one that we're experiencing now. So, come enjoy the fireworks at the Inner Harbor with us," Leach stated. 

Some Baltimore residents say they are adjusting their Fourth of July plans, staying inside until the fireworks. 

"We think we might do a cookout inside, yeah, just do it with the ninja girl rather than outside just to keep everything cool. And then we'll come out here in the evening when it's a little cooler," Tonia Edwards, a Little Italy resident, said. 

 If you are heading out for any Fourth of July activities, drink plenty of water throughout the day and take breaks from being in the sun. 

Therefore, the zoo has all kinds of protocols in place to make sure that all 1,800 animals stay cool and healthy. 

Red pandas

You wouldn't have found a red panda in sight if you had visited The Maryland Zoo on Friday, despite having air-conditioned logs, shaded areas, and temperature-controlled water bowls.

"The first choice the animals have is the choice of whether to be outside or whether to be inside where it's cool and air-conditioned. So right now, the red pandas are exercising that choice," Mike Evitts, Director of Communications at the Maryland Zoo, said. 

Evitts says especially for animals like red pandas, who are naturally found in cold weather, it's important that they can stay cool all summer, especially when the temperatures reach over 100 degrees. 

"Unlike people, most animals do not sweat. So, they can deal with hot temperatures in a couple of different ways. Obviously, they can drink water. They exchange hot air through panting and breathing like your dog at home might. They also just lie down. They don't move much; they stay in the shade, and they conserve their core temperature to try and keep their body temperature low," Evitts explained. 

African Elephants

On the other hand, African Elephants are accustomed to the heat. 

"They've lived in Maryland for many years, so we like to call them our Maryland elephants," Sarah Balzer, a zookeeper, told WJZ's Ashley Paul. 

Tuffy, the 44-year-old African Elephant, was loving the water cannon on Friday, one of many ways he stays cool during the heat wave. 

"The sand, the mud, they will put that all over their bodies, and that helps with bug repellent, all the nasty flies and everything, so that will help keep them from that. And it will act as a natural sunscreen too," Balzer added. 

Elephants have many blood vessels behind their ears, so when they flap them, they can lower their body temperature by up to 10 degrees. 

They also have the option to hang out in the mud wallows or swim. 

Otters

That's what the otters had been doing all day. 

"Obviously the otters have a really amazing pool of water and waterfalls and a lot of area to swim, but also if they want to dry out or want to use the restroom, they have lots of shore and sandy areas," Evitts said. 

Otters also have hollow logs to lay in that are ventilated if they need a break from swimming but want to stay cool. 

During the winter months, the zoo has a separate set of protocols to ensure the animals can stay warm and healthy. 

The Anne Arundel County Fire Department said the call came in shortly before noon. 

Two adults and two children were on a boating trip when the vessel went up in flames, the fire department said. 

A witness told WJZ-TV it happened off Rock Point in Fort Smallwood Park near Pasadena.

Video from the scene appears to show a speed boat with heavy flames and thick black smoke trailing behind. 

Fire officials said a charter boat helped turn the vessel to Knollview Drive. All four of the victims suffered burn injuries and were taken to Johns Hopkins Children's Center for treatment. 

At this point, there's no word on what caused the boat to catch fire. 

The fire was reported shortly after 11 p.m. Thursday on the 1500 block of West Patapsco Avenue in the Cherry Hill neighborhood. 

Firefighters arrived to find multiple food trucks engulfed in flames. No injuries were reported. 

The Fire Investigation Bureau was called, along with Arson detectives, and they are now handling the investigation. 

At this point, the cause of the fire has not been determined.
