UPDATED 1PM WEDNESDAY: A cold front from the north and a possible tropical depression to the south are combining to bring high winds and rough seas to Grand Cayman this week, according to the National Weather Service.
“a tropical depression is likely to form late this week or over the weekend.”
Weather Service forecaster Gilbert Miller said winds of 15 to 20 knots will likely begin overnight Wednesday or early Thursday, with higher gusts from the east and northeast. He said the cold front coming down from the United States will likely stall over Cayman for three to five days.
With the winds will come rough seas, especially in the east. The Weather Service anticipates it will be posting advisories for boaters from overnight Wednesday through at least Saturday. Forecasts put wave heights at 5 to 7 feet by Friday.
The west side of Grand Cayman should largely be protected from rough seas, but Mr. Miller said there will still be high swells in open water off Seven Mile Beach.
Mr. Miller said the combined weather systems will bring “patchy cloudiness” and some showers along West Bay Road in the coming days.
A late-season tropical system is south of Jamaica, and the Miami-based National Hurricane Center gives the large area of rainstorms an 80 percent chance of developing into a tropical depression in the next five days.
The Hurricane Center predicts, “Environmental conditions are expected to be conducive for slow development of this disturbance during the next several days, and a tropical depression is likely to form by late this week or over the weekend.”
Mr. Miller said, “I don’t want to call it a tropical cyclone.” He said the cold front is pushing the system to the east and it will not affect Cayman.
“The models show weak circulation,” he said, and the cold front will likely break up the storm.
