A surge of tropical moisture has returned across South Florida. This moisture surge will not only increase the risk for heavy rain and thunderstorms, but will increase the coverage of rain through the end of the week. Through Sunday, an additional widespread 2-3 inches of rain is possible, mainly across the East Coast of Florida.
MIAMI – Seemingly unending rain has returned once again to South Florida with daily afternoon thunderstorms enhanced by tropical moisture persisting through Sunday, part of what has been one of the wettest starts to September for many places along the state’s Gold Coast.
Miami has recorded more than 14 inches of rain since the start of the month.
A flash flood threat is in place for portions of the Gold Coast through Saturday morning.
The nonstop precipitation has actually helped ease drought conditions that have plagued much of the southern half of the Sunshine State this year.

Northern Florida stays out of the rain
It’s been a tale of two states in terms of precipitation this month. While South Florida has been swamped, the Florida Panhandle has stayed dry, with Tallahassee not recording a single drop this month – its driest start to September on record.
On the state’s Gulf coast, Tampa has only picked up 0.44 inches of rain, its third-driest start to September in history.
Meanwhile, the overall rain has been beneficial for Florida, which now has drought conditions across just 3% of the state, down from nearly 84% of the state as of early May.
