Weather alert: After record-breaking heat, storms move into South Florida

First came the searing heat. Now we’re getting soaked.

Stormy weather started to move in early Sunday in Miami-Dade and Broward, previewing the 80% chance of rain expected by the National Weather Service.

“We have rain rolling through South Florida,” CBS News Miami meteorologist Scott Withers said, noting a flash flood threat for coastal South Florida.

And it’s expected to peak from noon to 8 p.m., according to the weather service.

“Heavy rainfall, gusty winds, frequent lightning will be possible,” the National Weather Service warned.

The rain has changed plans at the big car race in Miami Gardens and the big golf tournament in Doral.

Sunday’s Formula 1 Crypto.com Miami Grand Prix will start at 1 p.m. instead of 4 p.m., to avoid the worst of the storms.

Weather also is affecting play at the Cadillac Championship golf tournament at Trump National Doral. The 7:30 a.m. start of the final round was “delayed due to a dangerous weather situation.” The gates opened at 9 a.m. and the first pair of players teed off at 9:30.

Sunday’s stormy weather arrives just after South Florida sizzled, breaking several heat records.

According to the weather service, Miami’s high of 94 on Saturday broke a 1937 record by one degree. Fort Lauderdale hit 95, breaking a 2002 record by two degrees. And West Palm Beach’s 96 broke a 1929 record by two degrees.

Sunday’s rains are cooling things off, with a forecast high of 84.

The all-day downpours will carry into Monday and Tuesday. By Wednesday, the sun returns, with a high of 86 and no rain chance through Thursday.
