A tropical wave brought widespread rainfall to South Florida Sunday. Moisture will continue to spread across central Florida through Monday.
The tropical wave associated with the rainfall crossed the Caribbean late last week.
Numerous showers and thunderstorms will spread from the Florida Keys, Miami and Fort Lauderdale into the Tampa Bay into Monday. The accompanying downpours will create hazards for motorists.
Showers and thunderstorms associated with the tropical wave expanded Saturday night into Sunday. Despite the tropical downpours, the possibility that this wave becomes a tropical depression remains low early this week.
The heaviest downpours will be blinding to drivers as visibility gets dramatically reduced. Runoff from the downpours could also pond on roadways, heightening the risk of vehicles hydroplaning. Both dangers may unfold on Interstate 95, Interstate 75 and U.S. Route 1.
Localized flash flooding incidents cannot be ruled out, especially in poor drainage areas.
Over the past 48 hours, numerous locations have received 2 to as much as 4 inches of rain from the tropical wave.
Residents and visitors may also find the timing of Monday's downpours rather inconvenient since outdoor plans will likely be forced inside.
Even if you decide to brave the torrential rain, be sure to seek shelter immediately if thunder is heard. You are then close enough to get struck by lightning.
Drier conditions are expected once again by Tuesday.
Another relatively dry stretch of weather will then follow for the rest of the upcoming week. Saharan dust should also return, leading to hazy skies and more vibrant sunrises and sunsets.
Meteorologist Bill Deger has more on the Saharan dust limiting Atlantic tropical activity.
