Tropical Storm Isaac Update 4 PM

12th September, 2018

At 4 PM the centre of Tropical Storm Isaac was located near latitude 15.4 North, longitude 56.6 West. Isaac is moving toward the west near 20 mph, and this general 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 (13th September), move into the eastern Caribbean Sea Thursday, and move into the central Caribbean Sea by the weekend.

Maximum sustained winds remain near 60 mph with higher gusts. Some weakening forecast during the next 48 hours. Tropical-storm-force winds extend outward up to 175 miles from the centre. The estimated minimum central pressure is 1003 mb (29.62 inches).

Key Points:

• Tropical Storm Isaac is expected to remain at tropic storm intensity when it moves across the Lesser Antilles by tomorrow bringing potentially life –threatening flash flooding to that area.

• Residents of the Cayman Islands should continue to monitor the progress of Tropical Storm Isaac as the official NHC forecast now places Isaac near the Cayman area by Monday.

• There is a reasonably high degree of uncertainty in the current forecast track and intensity.

Recommended Actions:

“At this time, Tropical Storm Isaac is not considered an imminent threat to the Cayman Islands but that could change,” explained the Honourable Tara Rivers, Minister responsible for Hazard Management Cayman Islands, “as we enter the more active phase of the hurricane season residents should have their hurricane preparedness plans well established and in place, and be ready to complete final arrangements such as shuttering and moving to safe shelter if necessary.”
