Forecasters were eyeing an area of low pressure located about 1,000 miles east of the Windward Islands early Wednesday.
The National Hurricane Center gave the area, which was still just a collection of showers and thunderstorms, a high, 70 percent chance of development into a tropical storm or tropical depression over the next 48 hours.
It was moving west-northwest at about 15 mph Wednesday. Computer models showed it reaching Puerto Rico and nearby islands by Friday, Bay News 9 Meteorologist Juli Marquez said.
"It's something that we're going to have to watch for that part of the Caribbean," Marquez said.
But predictions don't put the storm near Florida.
"Right now, it looks like it will be east of the Bahamas. But what kind of system it might be at that point, it's too early to say," Marquez said.
