Memorial Day rain chance: 90 percent for South Florida

Tropical moisture will bring thunderstorms, persistent downpours across Miami-Dade, Broward

Tropical moisture will continue to flow into our area for the rest of Sunday and even into Memorial Day.

PEMBROKE PARK, Fla. – Forget the outdoor barbecue, Memorial Day is going to be a washout. Chance of rain? 90 percent. The National Weather Service in Miami has a flood watch in effect for much of South Florida from Sunday through Tuesday.

Torrential rainfall is possible in the strongest storms, which will lead to possible flooding of poor drainage areas, small streams, creeks, and canals.

A few strong storms are possible with gusty winds and lightning.
