FORT LAUDERDALE, Fla. — South Floridians should keep an eye on an area of low pressure in the southwestern Caribbean Sea between Mexico's Yucatan Peninsula and Cuba.
The system is likely to bring heavy rain to South Florida through early next week. It's too early to tell if the system will track over the peninsula.
It has a 10% chance of developing in the next two days and a 30% chance of developing in the next five days, the National Hurricane Center said.
The next named storm to form would be called Zeta.
Near Bermuda, Hurricane Epsilon lost a bit more strength Thursday afternoon. Epsilon is still a Category 1 storm, but its winds are down to 85 mph, according to the 5 p.m. EDT advisory from the hurricane center.
The 85 mph reading represents a 15 mph drop in wind speed since the 8 a.m. advisory.
Epsilon, the season's 10th hurricane, was 200 miles east of Bermuda and moving north-northwest at 9 mph.
Tropical-storm-force winds extend outward up to 240 miles, a 70-mile reduction from Thursday afternoon. Hurricane-force winds extend 15 miles from the center.
"Satellite images indicate that the eye of Epsilon has lost definition over the past several hours," the hurricane center said.
Epsilon is expected to track northward overnight and continue on that path for the next day or two. It could strengthen slightly as it has a trough interaction and travels over a small warm eddy near the Gulf Stream either Friday or Saturday.
