Miami faces scattered showers and thunderstorms Thursday, with a high near 88 degrees.

Storms Arrive Early And Return Through The Afternoon

The latest forecast calls for scattered showers and thunderstorms throughout the day, especially during the afternoon and early evening. Northeast winds around 14 mph could gust near 20 mph, making the weather feel blustery between downpours.

The National Weather Service in Miami says stronger storms could produce heavy rain and localized flooding, especially in urban and low-lying areas. Rainfall chances are around 70% Thursday, and a quarter to half an inch of rain is possible in the Miami area.

Weekend Rain Chances Climb Across South Florida

Friday will remain warm, with a high near 88 and an 80% chance of showers and thunderstorms. The wetter pattern becomes more persistent Saturday and Sunday, when rain chances rise to about 80% and 90%, respectively, while afternoon temperatures stay in the upper 80s.

Showers and thunderstorms are expected to continue into Monday, Tuesday and Wednesday, with highs generally in the upper 80s to lower 90s. Overnight lows will remain mostly in the upper 70s.

The extended wet pattern reflects increasing tropical moisture moving into South Florida, according to the National Weather Service. Weak winds could allow heavy rain to linger over the same neighborhoods, raising the risk of street flooding even when storms are not severe.

Beachgoers And Boaters Face Extra Hazards

Atlantic beaches from Miami-Dade through Broward face an elevated rip-current risk, while the risk is high in Palm Beach County through Friday morning. Anyone entering the water should swim near a lifeguard and follow beach flags, especially as northeast winds and elevated surf continue.

Boaters should also check the latest marine advisories before heading out, with hazardous conditions expected in Gulf waters through Thursday evening. Miami's storm outlook is a substantial update from Hoodline's earlier forecast, as the weekend rain threat now looks broader and more persistent.
