The National Weather Service has issued a significant weather advisory for metro and inland Palm Beach County with a line of strong thunderstorms stretching from Royal Palm Beach to Coral Springs.
Forecasters said hail, wind gusts to 55 mph and lightning are the biggest concerns with these storms, which are nearly stationary.
Torrential rainfall is also occurring with these storms.
A second Florida man was killed by lightning Tuesday in Pembroke Pines. It is the top weather-related killer in Florida.
Areas of concern this afternoon include West Palm Beach, Wellington, Royal Palm Beach, Boca Raton, the Acreage and Loxahatchee Groves.
The advisory is in effect until 4:15 p.m., but forecasters said with the storms not moving, there remains a concern throughout the day for small hail, locally heavy rainfall and gusty winds.
Meteorologists in Miami said both the Gulf and Atlantic sea breezes developed with the heating of the day, helping to trigger the storms.
They note in their forecast the potential for an increased threat of waterspouts over the Atlantic and Lake Okeechobee this afternoon.
