On the forecast track, Melissa is expected to be nearer to Jamaica and the southwestern portion of Haiti during the next couple of days. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is expected during the next day or so, but significant strengthening is expected by late Friday and over the weekend.

RAINFALL: Melissa is expected to bring 5 to 10 inches of rain to the southern Dominican Republic, southern Haiti, and eastern Jamaica through Sunday, with locally higher amounts possible.
