With or without a name, the storm heading our way will create a very wet Saturday

Potential Tropical Cyclone No. 18 remains on its path to Cuba, South Florida and the Bahamas, still not blowing hard enough to get named Tropical Storm Philippe.

Whether it works its way up to a name or stays a number, the storm should create extra wetness in an already soggy South Florida. Saturday’s 8 a.m. advisory puts it 250 miles south-southwest of Havana, Cuba, moving north-northwest at 10 mph with maximum sustained winds of 35 mph.

In South Florida, the thunderstorms are expected to start around 11 a.m., and then last though early Sunday morning. While no flood advisories are in effect at this point, some areas could see as much as four inches of rain.

The National Weather Service also says some “brief tornadoes” are possible for South Florida and the Keys Saturday.

“Strengthening is forecast during the next 48 hours, and the disturbance is expected to become a tropical storm later today,” says the National Hurricane Center’s 8 a.m. advisory. “On the forecast track, the center will move across western Cuba this afternoon, across the Straits of Florida tonight, and across the northwestern Bahamas Sunday morning.”

A Tropical Storm Warning is in effect for the Northwestern Bahamas as well as the Cuban provinces of Isla de la Juventud, La Habana, Ciudad de laHabana, Matanzas, Cienfuegos, and Villa Clara. There’s a Tropical Storm Watch for the Central Bahamas.
