5PM UPDATE: HURRICANE IRMA NOW CATEGORY 4 HURICANE

September 4, 201710122Views

A Hurricane Watch remains in effect for the British Virgin Islands.

A hurricane watch means hurricane conditions are possible within 48 hours.

According to the National Hurricane Centre, at 500 PM , the centre of Hurricane Irma was located near latitude 16.7 North, longitude 54.4 West.  Irma is moving towards the west near 13 mph and this general motion is expected to continue into Tuesday, followed by a turn toward the west-northwest late Tuesday.

On the forecast track, the center of Irma will move approximately 35 miles north east of the British Virgin Islands on Wednesday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 130 mph with higher gusts.  Irma is now a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.  Additional strengthening is forecast during the next 48 hours.

Hurricane-force winds extend outward up to 40 miles from the centre and tropical-storm-force winds extend outward up to 140 miles.

The latest minimum central pressure reported by reconnaissance aircraft is 944 mb.

PROBABLE IMPACTS FOR ROAD TOWN

Wind

Winds 80 mph to 110 mph is possible in some locations with higher gusts at elevated areas and on the northern coast of Tortola as well as the northern islands including Anegada.

Rainfall

Rainfall amounts of 8 to 14 inches are likely and this would likely cause street flooding and travel delays. Mudslides are possible in the mountainous areas.

 Storm Surge

With the track north of the British Virgin Islands, a storm surge of up to 6-8 feet will be possible on Tortola and increased up 10-14 feet for the northern islands including Anegada. This would result in damage to coastal structures.
