MiamiHerald / So much for South Florida’s brush with fall.
A tropical system swirling off the coast of Central America is expected to wrap the region in a muggy embrace this weekend, dumping heavy rain and returning temperatures to the 80s. Beginning late Friday or early Saturday, moisture from the system is expected to generate two to four inches of rain across South Florida, continuing through Saturday into the evening.
The system, which has lingered in the Caribbean all week, could still gain intensity as it moves north over warm ocean water and encounters weak wind shear, becoming a late season tropical depression or storm. But National Weather Service forecasters said Thursday the bigger threat to Irma-soaked South Florida is rain.
