DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Melissa was located near latitude 14.3 North, longitude 74.6 West. Melissa is moving toward the west near 2 mph (4 km/h). A slow forward speed and a gradual turn to the northwest or north-northwest is forecast during the next couple of days, followed by a westward turn by this weekend. On the forecast track, Melissa is expected to be nearer to Jamaica and the southwestern portion of Haiti later this week. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some slow strengthening is forecast during the next few days, and Melissa could become a hurricane by Friday, with more substantial intensification forecast by this weekend. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1003 mb (29.62 inches).

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