A Flash Flood Warning was issued Monday afternoon for parts of Miami-Dade County, with severe weather bringing flight delays, lightning hazards and the threat of widespread flooding.

The NEXT Weather Alert will continue through the afternoon as storms intensify across the region.

Warning covers major Miami-Dade communities

The National Weather Service says the warning includes Miami International Airport, Miami, Hialeah, Coral Gables, Miami Springs and Allapattah.

Forecasters caution that slow-moving storms could cause dangerous road conditions in low-lying areas.

Ground stop issued at Miami International Airport

Operations at Miami International Airport were significantly disrupted Monday afternoon as storms rolled through.

"There is currently a ground stop for flights arriving at MIA. There is also a hold for departures because of lightning in the area since 2 p.m.," said Greg Chin, Communications Dvision Director for the Miami-Dade Aviation Department.

The airport resumed normal operations a short time later. 

Storms bring flash flooding threat

The unsettled weather marks the start of a stormy week in South Florida.

The Weather Prediction Center placed the region under a marginal, level 1 out of 4, risk for flash flooding due to heavy downpours. Temperatures climbed into the low 90s Monday, fueling storm development.

The heating of the day, combined with abundant moisture, triggered strong thunderstorms during the afternoon and evening hours. Minor coastal flooding was also possible Monday with higher-than-normal king tides, with high tide readings at 9:55 a.m. and 10:13 p.m. in Fort Lauderdale, 9:42 a.m. and 10 p.m. in Miami, and 11:07 a.m. and 11:22 p.m. in Key West.

More rain expected through midweek

The chance of rain remains high Tuesday, with another round of widespread storms expected. A marginal risk of flash flooding continues for much of South Florida, raising the possibility of localized inundation.

Conditions are forecast to stay unsettled through Wednesday before rain chances gradually decrease late in the week. Highs will remain seasonably hot near 90 degrees, with feel-like temperatures climbing into the upper 90s and low 100s by the weekend.
