Published 14th September 2018, 4:27pm

At 4 PM - News in from the NHC confirms Isaac has regained Tropical Storm strength. The centre of Isaac was located near latitude 15.3 North, longitude 67.3 West. Isaac is moving west near 14 mph with maximum sustained winds of 40 mph. A westward track with some decrease in forward speed is expected for the next few days, followed by a possible turn to the west-northwest late Sunday. On this track the storm could be close to the Cayman Islands by Monday morning.

Little change in strength is forecast during the next 36 hours but Isaac is currently forecast to weaken to a Tropical depression on Sunday and degenerate into an open wave on Monday.

It should be noted that there remains significant uncertainty in the intensity forecast for Isaac and the NHC is already advising Isaac could deliver 4 to 6 inches of rainfall to Jamaica with the possibility of flash floods to that Island.

Tropical Storm force winds currently extend outwards 45 miles for the centre of circulation and the estimated minim central pressure is 1003 mb

Residents in the Cayman Islands are urged to closely follow the progress of Tropical Storm Isaac as changes to the forecast track and intensity are possible.


The Cayman Islands Government is following the current forecast of the NHC which indicates Isaac will weaken to a Tropical Depression then an open wave, however local residents are asked to closely follow the official forecasts over the weekend and maintain high levels of preparedness.
