A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Haiti, the Dominican Republic, and eastern Cuba should monitor the progress of Melissa. A hurricane warning will likely be required for Jamaica later today. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Tropical Storm Melissa was located near latitude 16.2 North, longitude 75.4 West. Melissa is drifting toward the north near 2 mph (4 km/h). A slow northward or north-northeastward motion is forecast during the next day or so, followed by a sharp turn westward over the weekend. On the forecast track, Melissa is expected to move closer to Jamaica and the southwestern portion of Haiti during the next couple of days. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Gradual strengthening is forecast over the next day or so, followed by rapid intensification this weekend. Melissa is forecast to become a hurricane by Saturday and a major hurricane by the end of the weekend. Tropical-storm-force winds extend outward up to 140 miles (220 km) to the east of the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Melissa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Hurricane conditions are possible within the watch area in Haiti on Saturday and Jamaica beginning late Saturday or Sunday. Tropical storm conditions are expected to begin in Haiti later today and in Jamaica on Saturday. RAINFALL: Melissa is expected to bring 8 to 14 inches of rain to the southern Dominican Republic, southern Haiti, and eastern Jamaica through Sunday, with locally higher amounts possible. Additional heavy rainfall is likely beyond Sunday; however, uncertainty in Melissa's track and forward speed reduces confidence in exact totals. Significant, life-threatening flash flooding and numerous landslides are expected in the southern Dominican Republic and eastern Jamaica, with catastrophic flash flooding and landslides anticipated in southern Haiti. Across the northern Dominican Republic, northern Haiti, and western Jamaica, 2 to 4 inches of rain are expected through Sunday. Flash and urban flooding will be possible through Sunday. Flooding impacts may increase across western Jamaica next week. For a complete depiction of forecast rainfall associated with Melissa, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: Minor coastal flooding is likely along the coast of Jamaica by Saturday in areas of onshore winds as tropical storm conditions begin to reach the area. However, there is a potential risk of a more significant storm surge, especially along the south coast of Jamaica, early next week. Due to Melissa's slow motion and large forecast uncertainty, it is still too soon to know exactly how high the storm surge could reach. SURF: Swells generated by Melissa are expected to affect portions of Hispaniola, Jamaica, and eastern Cuba during the next several days. Please consult products from your local weather office.
