2023-09-24 14:11:45

Tropical Storm Phillippe is expected to gradually gain strength and a new system that emerged off Africa might become a tropical depression by midweek, according to National Hurricane Center forecasters.

As of 11 a.m. Sunday, Phillipe was located regarding 1,155 miles west of Africa’s Cabo Verde Islands, moving west at 12 mph with maximum sustained winds of 50 mph. The same general motion, but slightly slower, is expected over the next few days as the storm gradually strengthens, however, its precise path  is uncertain. Some models show it strengthening during the next few days, while others show it weakening as a result of the shear from an upper-level trough

It is currently expected to curve north before reaching South Florida, with that likely occurring mid-week.

“While it shows a due-west path, there is expected to be a curve to the north,” said Donal Harrigan, a meteorologist for the National Weather Service Miami. “There’s tons of uncertainty as to how far west or east we’ll go with that curve. I’m not seeing anything that raises a large concern of something reaching South Florida. It looks like this thing is going to stay east of us.”
