Forecast


The disturbance continues to move quickly to the west. A gradual west-northwest turn is expected during the next day or two and this track should continue for the next several days. On this track, the disturbance is expected to move through the Lesser Antilles Sunday morning and in the general direction of the Dominican Republic or Jamaica early next week. The confidence in the track forecast remains average.


The disturbance is better organized this morning and conditions are becoming more favorable for development. Therefore, forecasters have increased the chances of the disturbance becoming a tropical cyclone to 40 percent through the next 48 hours and to 90 percent afterward. If the system does develop, there does not appear to be much that will keep it from reaching hurricane intensity. Confidence in the intensity forecast remains average.


Expected Impacts on Land


Lesser Antilles: Squalls are likely to move over the Leeward and northern Windward Islands on Sunday morning. 4-6 inches of rain are likely.


U.S. and British Virgin Islands: Squalls are expected to move into the U.S. and British Virgin Islands around Monday.
