An unusual storm system that is expected to develop off the coast of the southern United States will have little or no impact on the Cayman Islands, meteorologist Allen Ebanks said on Monday.

A low trough of pressure in mid-Georgia is expected to slide south into the Gulf of Mexico and develop into a low pressure system.

On Monday, the National Oceanic and Atmospheric Administration said the system had an 80% chance of developing into a cyclone, partly due to high ocean surface temperatures. The 87-degree surface temperature is three to four degrees warmer than normal.

If the depression’s winds reach 39 mph, it would become Tropical Storm Barry, and NOAA stated that it may bring heavy rainfall along portions of the northern and eastern US Gulf Coast later this week.

But Ebanks said any impact on Cayman is unlikely.

“Once it gets up in the gulf there,” he said, “it’s very, very rarely that it comes back down toward us.”

If anything, he said, the islands may feel a change in the wind, with an increased south, southeasterly flow.
