Omar has been downgraded from a hurricane to a tropical storm as it continues to move out into the Atlantic Ocean.
The U.S. National Hurricane Center says the storm is now carrying winds of 110 kilometers an hour, and moving towards the northeast at 41 kilometers an hour.
Forecasters expect some additional weakening over the next few days.
Omar passed by the northern Leeward Islands late Wednesday carrying winds up to 205 kilometers an hour, making it a dangerous Category Three storm on the five-level scale that measures a hurricane's power and potential destructiveness.
The storm flattened trees, triggered minor flooding and mudslides, and left residents without electricity, but caused no major damage.
