Forecasters with the Cayman Islands National Weather Service are keeping their eyes on a broad area of low pressure, currently lingering south of the islands, near Panama.
The U.S.-based National Hurricane Center on Tuesday forecast the system at a 20 percent chance of tropical storm formation by Sunday.
“Some gradual development of this system is possible late this week and this weekend while the low drifts generally northward during the next several days,” the NHC said.
Local meteorologist Avalon Porter, however, said it was still too early to judge the potential of the system.
“It’s going to linger over us for the next week or so and then it will move into the Gulf of Mexico,” Mr. Porter said.
“It’s a little early to tell how strong it’s going to get or what it’s going to do.”
He said the heavy rains that fell Monday and Tuesday were unrelated to the system. Instead, those rains were the result of a tropical wave and upper-level trough west of Cayman.
He expected Wednesday would bring a temporary break from the showers. By Thursday, however, more showers could fall, resulting from a low-pressure system coming from Cuba.
