Localized flooding possible in South Florida Monday as region braces for more downpours, thunderstorms



It was a wet and stormy weekend across South Florida, and it’s looking like that trend will continue as we kick off the new workweek.

Another round of scattered showers and thunderstorms will move into South Florida on Monday, and the region is under a marginal risk (Level 1) of severe weather due to the threats of storms capable of producing damaging wind gusts and small hail.

Heavy downpours and localized flooding will also be possible.

The first wave of weather will move in later on Monday morning through midday and into the afternoon hours.

More widespread storms are likely later Monday night and overnight as a cold front pushes through.

And heads up for spring breakers in South Florida – there’s a dangerous risk of rip currents along the Atlantic beaches. It’s not safe to go swimming in the ocean.

And a small craft advisory is in effect for the Atlantic and Keys waters. Either way, Monday won’t be the best day to head to the beach or go boating due to the scattered storms expected and the clouds around.
