DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Hurricane Elsa was located near latitude 15.5 North, longitude 67.8 West. Elsa is moving toward the west-northwest near 29 mph (46 km/h), and this general motion is expected to continue today. A decrease in forward speed is expected tonight and Sunday, followed by a turn toward the northwest Sunday night or Monday. On the forecast track, Elsa will move near the southern coast of Hispaniola late today or tonight, and move near Jamaica and portions of eastern Cuba on Sunday. By Monday, Elsa is expected to move across central and western Cuba and head toward the Florida Straits. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Some restrengthening is possible today, but slow weakening is expected to begin tonight or Sunday as Elsa interacts with the landmasses of Hispaniola, Jamaica, and Cuba. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Elsa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and on the web at www.hurricanes.gov/graphics_at5.shtml?key_messages. WIND: Hurricane conditions are expected in the hurricane warning area in Haiti and the Dominican Republic by late today. Hurricane conditions are expected on Jamaica tonight or Sunday, and are possible in eastern Cuba on Sunday. STORM SURGE: A storm surge will raise water levels above normal tide levels by as much as the following amounts in areas of onshore flow within the hurricane watch and warning areas... Southern coast of Cuba...4 to 6 feet Southern coast of Hispaniola...2 to 4 feet Jamaica...1 to 3 feet RAINFALL: The outer rain bands associated with Elsa will begin to impact Puerto Rico in a few hours with rainfall totals of 1 to 3 inches with localized amounts of 5 inches possible today. This rain may lead to isolated flash flooding and minor river flooding, along with the potential for mudslides. Across portions of southern Hispaniola and Jamaica, rainfall of 4 to 8 inches with isolated maximum amounts of 15 inches is possible today and Sunday. This rain may lead to scattered flash flooding and mudslides. By early next week, Elsa is expected to impact portions of the Cayman Islands and Cuba producing 5 to 10 inches of rain, with isolated maximum amounts of 15 inches. This rainfall may result in significant flash flooding and mudslides. SURF: Swells generated by Elsa will spread westward across the Caribbean Sea through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
