Thunderstorms and flash flooding are expected all week in South Florida.

South Florida is facing a wet week, with heavy rain and the potential for flooding.

Starting Tuesday, expect widespread showers and thunderstorms, according to the National Weather Service.

“It’s tough to pinpoint exactly how much rain each area will get, but the general expectation is for substantial rainfall through Thursday,” National Weather Service Miami meteorologist Luke Culver said Monday.

“The key is to stay weather-aware,” Culvert said. “Make sure you have a way to receive warnings so that if you find yourself in a flash flood warning, you can quickly move to higher ground or avoid flooded areas.”

The good news?

The rainy weather will bring us some relief from the extreme heat. High temperatures this week are expected to cool down to the mid- to upper-80s, compared to the 90s over the past few weeks, when it sometimes felt more than 100 degrees with the humidity.

Father’s Day forecast

Looking ahead to the weekend and Father’s Day on Sunday, the wet pattern might begin to ease.

“By Sunday, there’s a potential for less rain, although some showers and thunderstorms are still likely,” Culvert said. “It doesn’t look as wet as the rest of the week.”
