Significant model uncertainty exists so residents should monitor this system carefully

Published 11th September 2018, 10:35am

At 10 am local time, the centre of Tropical Storm Isaac was located near latitude 14.6 North, longitude 49.7 West. Isaac is moving toward the west near 16 mph (26 km/h) and this motion is expected to continue for the next few days. On the forecast track Isaac is anticipated to move near or over the central Lesser Antilles on Thursday and move into the eastern Caribbean Sea Thursday night.

Maximum sustained winds remain near 70 mph (110 km/h) with higher gusts. Isaac is expected to be near hurricane strength when it moves through the central Lesser Antilles, with some weakening forecast afterward on Friday.

Tropical-storm-force winds extend outward up to 105 miles (165 km) from the centre.

There remains some significant uncertainty in the models for the intensity and track of Isaac so residents of the Cayman Islands should monitor the progress of this storm closely.
