Hurricane Irma Summary:

Current Location: 18.8 degrees North, 39.1 degrees West

Geographic Reference: Approximately 1760 miles east of the Northern Leeward Islands

Movement: West at 13 mph

Max Winds: 120 mph with higher gusts

Hurricane Force Winds: 25 miles

Current Radius of Tropical Storm-Force Winds: 105 miles

Minimum Central Pressure: 964 Millibars

 Key Points

  1. Irma has regained strength and may develop into a category 4 hurricane by tomorrow.
  2. Irma may pass very close to the northeast Caribbean islands as a major hurricane next Wednesday.

Satellite imagery this afternoon indicates that Irma finished its eyewall replacement cycle a few hours ago and is now strengthening as the new eye shrinks in size. Irma will likely become a Category 4 hurricane tomorrow as it continues tracking generally westward at about 13 mph.  Forecasters have made a minor northward track adjustment as Irma passes the Leeward Islands.

The westward turn of Irma has begun.  A building mid-level high should cause the hurricane to turn west-southwestward tomorrow and continue through early next week.  Thereafter, Irma should reach the southern periphery of the ridge, and begin to move west-northwestward.

Expected Impacts on Land:

Northeast Caribbean Islands: Squalls will reach the area next Tuesday night with possible tropical storm-force or greater winds affecting the area next Wednesday.

The Department of Disaster Management (DDM) is strongly encouraging all persons to use the time now to intensify preparations for any potential impact.

Irma has the potential to cause significant rainfall, strong winds and storm surge across the Territory, if it moves into or near the British Virgin Islands.  Residents and businesses in low-lying, coastal and flood prone communities will need to take steps to minimize or prevent flooding, check roofs, clear roof gutters and drains around your property and inspect your cistern outflows.  Individuals are encouraged to utilize flood protection items such as flood boards and sand bags to prevent or slow the flow of water into their homes and businesses.

The DDM will continue to monitor this system into the weekend and will provide updates and preparedness information.  Please ensure that you are able to access these updates and we urge you to act on the information that is being provided.

Advisories and information can be obtained from local media stations, DDM’s website ( and Facebook at BVIDDM.
