An extensive area of disorganized showers and thunderstorms is expected to move into the western Caribbean Sea in coming days.

The system, currently located near the northeastern coasts of Nicaragua and Honduras, was forecast by the U.S.-based National Hurricane Center at a 40 percent chance of tropical formation by Tuesday.

Forecast mapping as of Thursday, however, showed the system missing the Cayman Islands and moving toward the Yucatan Peninsula.

Despite low surface pressure, upper-level winds were not favorable for tropical cyclone formation as of Thursday afternoon.

“Environmental conditions could become less hostile by late this weekend or early next week, and a tropical depression could form as the system moves slowly northwestward across the northwestern Caribbean Sea and the southern Gulf of Mexico,” the NHC said.

The Cayman Islands National Weather Service advised that small craft should exercise caution, as seas will be moderate to rough with waves reaching up to 6 feet.

Hurricane Leslie, located in the north-central Atlantic, posed no threat to Cayman.
