(CBS News) Millions are facing another day of dangerous weather.
Tornadoes, hail and strong winds threaten much of the central and southern Midwest, and flash flooding could hit the Northern Plains and the Northeast.
People in Kansas woke up Wednesday to damage left behind by two tornadoes, reporter Justin Surrency of CBS affiliate WIBW-TV Topeka, Kan., reports.
The first massive twister touched down around 4:30 p.m. local time in Corning, Kan., an hour north of Topeka.
The storm packed winds estimated up to 150 mph as residents braced for a second straight day of tornadoes in the region.
"We had the five kids in the basement in the shower," said Monica Becker. "We stood there taking pictures for a little bit. My husband was taping, and he said, 'Get down there now,' and it hit, and it was as loud as they say it is."
Eighteen buildings were damaged in the storm. Some were completely destroyed.
"We lost three sheds," said Becker. "I just- there's no words."
Later in the afternoon, another tornado touched down a bit farther west, in Bennington, and stayed put for more than an hour.
There were no reports of injuries in either storm, and locals were confident they can bounce back.
"It's a tight-knit community," said Galen Niehues. "If it would happen to anybody, we could rely on the neighbors coming out and helping us, so it's just the way we are here in a rural community."
Twisters also ripped through two other states Tuesday night.
A tornado touched down near, Erie, Pa. That one destroyed at least one mobile home.
Just outside Flint, Mich., another tornado made land close to a high school.
No injuries are reported in either of those storms.
Wednesday's risk is being called moderate, but that is exactly the same warning the people of Oklahoma got before last week's deadly tornado in the city of Moore.
Meteorologist Jeff Berardelli of CBS Miami station WFOR-TV reports that Wednesday's major threats are especially in central and western parts of Oklahoma and also in central and western Kansas.

Oklahoma City, Wichita, Kan., and maybe as far north as Kansas City are some of the major cities in the path of the potential severe weather.
Berardelli expects to see widespread, long-lived, maybe strong tornadoes especially across the Plains states.
There's also a slight risk for severe weather in upstate New York, northern parts of Pennsylvania and as far south as New York City.
On Thursday, the threat shifts from the eastern Plains states into the Midwest, which could include Little Rock, Ark., St. Louis and maybe bordering on Chicago.
A strong jet stream in the atmosphere means there's potential for severe weather for each of the next several days. This could be the most active week of the season so far.
