A marine warning has been issued for all of the Cayman Islands for Monday and Tuesday as a strong cold front is expected to enter the area tomorrow morning. The Cayman Island National Weather Service reports a strong high-pressure system behind the front over the northeastern Gulf of Mexico. As the front moves east of the Cayman Islands, near gale-force winds and very rough seas are anticipated due to the increasing pressure gradient across the northwest Caribbean.
Residents should prepare for wave heights of four to six feet through the day tomorrow, increasing to nine to 13 feet overnight, with swells of one to three feet likely along the south and west coasts. On Tuesday, wave heights are forecasted to be nine to 13 feet, decreasing to eight to ten feet by evening, with swells of up to five feet along western coasts during the day.
Winds on Monday will start as moderate west to southwest, 10-15 knots in the early morning, before veering westerly by the afternoon. Wind speeds will rise to up to 20 knots, with strong to near-gale force west to northwest winds of up to 30 knots expected by late evening. Similarly, on Tuesday, strong to near-gale force west to northwest winds of up to 30 knots are forecasted, with higher gusts in the early morning decreasing by the evening.
The weather service advises all residents to exercise caution.
Hazard Management Cayman Islands notes that given the forecast information for westerly winds, the west coast of Grand Cayman, Cayman Brac, and Little Cayman could potentially experience more significant impacts than other coastal areas. Residents should be aware that swells could begin affecting the western coasts, including Seven Mile Beach and the George Town Harbour area, as early as Sunday. Vessels are advised to seek safe shelter.
