The NEXT Weather Team is tracking two rounds of pop-up storms across South Florida this afternoon and early evening hours.

On Wednesday, the weather service issued a heavy rainfall and urban flooding threat alert. The reasons: Rounds of heavy rainfall Wednesday through Saturday may lead to localized urban flooding, with the greatest threat for flooding across the east coast metro of South Florida. The threat of flooding is both a day and an overnight concern.

For the rest of the week, Southern California will feel more like "Florida West," forecasters said, as remnants of Tropical Storm Mario move north, boosting humidity and the chance for strong thunderstorms.

Here's when fall 2025 officially begins and when the cooler weather is expected to follow in Florida this year.
