DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Elsa was located near latitude 14.8 North, longitude 66.3 West. Elsa is moving toward the west-northwest near 29 mph (46 km/h), and this general motion is expected to continue through Saturday. A decrease in forward speed is expected Saturday night and Sunday, followed by a turn toward the northwest Sunday night or Monday. On the forecast track, Elsa will move across the eastern Caribbean Sea tonight across the central Caribbean Sea on Saturday, and move near the southern coast of Hispaniola late Saturday or Saturday night. By Sunday, Elsa is forecast to move near Jamaica and portions of eastern Cuba, and move near portions of central and western Cuba Sunday night and Monday. Data from an Air Force Reserve reconnaissance aircraft indicate that maximum sustained winds have decreased to near 80 mph (130 km/h) with higher gusts. Little change in strength is forecast tonight, with some restrengthening expected on Saturday. Slow weakening is expected to begin Saturday night or Sunday as Elsa interacts with 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 based on dropsonde data from the aircraft is 995 mb (29.39 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 Saturday. Hurricane conditions are expected on Jamaica late Saturday 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 tonight with rainfall totals of 1 to 3 inches with localized amounts of 5 inches possible through Saturday. 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 Saturday into 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.
