Rainfall, strong winds and rough seas forecast for Cayman Islands

Published 2nd August 2016, 7:40am

A strong tropical wave south of Kingston, Jamaica, continues to move quickly westward at about 20 mph. This system is likely to be upgraded to a tropical storm by the National Hurricane Center as the environmental conditions are expected to be conducive for additional development throughout the day. Thunderstorm activity associated with the wave remains organized, but the system still appears to lack a closed surface circulation. Regardless of development, locally heavy rainfall and strong winds, perhaps peaking to tropical storm force strength, can be expected from later today into this evening mainly across Grand Cayman. The weather impacts on the Sister Islands will be just slightly less than that expected over Grand Cayman and resident should still remain attentive to the weather bulletins.

Grand Cayman and the Sister Islands can expect an increase cloudiness and showers from afternoon as the wave moves into area. The current models indicate that rainfall maxima will pass to the south of Grand Cayman with 1 inch of rainfall expected over the Cayman Island; however, there is the potential for heavy showers along the periphery of the tropical wave which may lead to higher accumulation and to flooding of low lying areas. All residents should continue be attentive to any new weather bulletin that will ensue.

Moderate to strong east to southeasterly winds and rough seas with wave heights of 4 to 6 are expected this morning, becoming very strong with wave heights increasing to 7 to 9 feet by this evening. All marine interests should seek safe harbor and remain there until further notice.

The next bulletin will be issued at 11 a.m. later this morning.
