Tropical Storm Dorian has weakened to maximum sustained winds of 45 mph as it moves swiftly west-northwest at 21 mph through the Atlantic Ocean. As of 11 am, Friday, the storm was nearly 1,300 miles east of the northern Leeward Islands. The storm is not forecast to intensify significantly in the next several days as it continues on a general westerly track. The latest computer model forecast consensus is a bit farther south than previous projections. The forecast track is far enough south that the storm will have an impact in the Caribbean islands, but it is not expected to be a strong tropical storm or hurricane at that time. The storm will be encountering dry air and wind shear in the next couple of days, and may degenerate to a tropical wave.
