Weather alert: South Florida flood watch extended to Thursday as storms continue
Most of South Florida is under a flood watch that has been extended to Thursday, with forecasters calling for heavy rain, gusty winds and scattered thunderstorms.
The watch will be in effect for most of Miami-Dade and Broward counties and parts of Palm Beach County until 8 p.m. Thursday. Forecasters are predicting that heavy rain should become less widespread Thursday, but flooding remains possible due to saturated ground, according to the National Weather Service.
The region is expected to see about 1 to 2 inches of rain, with isolated amounts of greater than 4 inches possible. Over the last 48 hours, many South Florida areas saw more than 2 inches of rain, with isolated patches of 6 to 8 inches, NWS Miami tweeted at 5 p.m.

The heavy rains have coincided with the king tides, the highest tides of the year, which started last Wednesday and ran through this Wednesday, according to NOAA.
“Heavy rainfall may produce flooding and/or flash flooding in urban locations as well as small creeks, streams, and canals. This is especially true for areas that recently received heavy rainfall, and for areas near the coast due to the combination of heavy rain and astronomically high tides,” according to the National Weather Service flood watch advisory.
Areas under the flood watch include West Kendall, Miami Beach, Homestead, downtown Miami, Doral, Hialeah, Aventura, Miami Gardens, Miramar, Davie, Fort Lauderdale, Hollywood, Boca Raton, Pompano Beach, Plantation, Pembroke Pines and West Palm Beach.
The Middle and Upper Keys flood advisory has also been extended to Thursday morning.
Delays at Fort Lauderdale Hollywood Airport
The rain has caused delays at Fort Lauderdale Hollywood International Airport.
Just before 11 a.m. Wednesday, the airport issued a tweet to alert passengers that the heavy rainfall has flooded the entrance to arrivals and departures from Perimeter Road and that that road was temporarily closed due to the flooding.
“Motorists are advised to use alternate entrance routes into the airport from US-1 or Interstate 59,” FLL suggested.
