Grand Cayman will experience rough seas, windy conditions and cooler temperatures this weekend as a result of a seasonal nor’wester storm that will come into the area on Saturday.
Meteorologist Kerry Powery of the Cayman Islands National Weather Service said the cold front, which was associated with the blizzard that affected the American Midwest this week, should arrive Saturday morning.
“The winds will pick up out of the north in the afternoon and then the north-northwest in the evening,” he said, adding that by Sunday, the winds are expected to come straight out of the northwest.
“From what I’m seeing now, the winds might get up to 20 knots with higher gusts,” he said.
Nor’wester is a term used for seasonal weather systems that bring winds directly from the northwest. Mr. Powery said nor’westers typically occur during the winter months up through the end of March. Nor’westers are potentially dangerous because they bring high surf to the west coast of Grand Cayman, including the Northwest Point area of West Bay, most of Seven Mile Beach, George Town and South Church Street.
The rough seas will impact boating and water sports activities. A small craft advisory will be in effect from Saturday and a small craft warning, meaning small crafts should be in safe harbour, is in effect on Sunday and Monday. Wave heights are expected to reach 4 to 6 feet on Saturday and 6 to 8 feet on Sunday.
The rough seas in George Town harbour will likely delay cargo ship deliveries, impacting the supply of foods next week. The weather system will also cool things down a bit. “We’ll have a little cloud cover and the front will be pulling down some of the cold air from our friends up north,” Mr. Powery said.
Sunday’s high temperature is expected to be 84 degrees, with a low down to 72 degrees and on Monday the high is expected to reach 82 degrees.
One thing the weather system won’t likely bring is rain. “I don’t really see much rain with it,” Mr. Powery said. “Maybe we’ll get a little when the front first comes into the area.”
