DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Elsa was located near latitude 16.5 North, longitude 70.3 West. Elsa is moving very quickly toward the west-northwest near 31 mph (50 km/h). A decrease in forward speed is expected later today 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 later today and 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 75 mph (120 km/h) with higher gusts. Little change in strength is expected today, but slow weakening is forecast on Sunday and Monday when Elsa is expected to be near or over Cuba. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 999 mb (29.50 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 later 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...3 to 5 feet Southern coast of Hispaniola...2 to 4 feet Jamaica...1 to 3 feet RAINFALL: The outer rain bands associated with Elsa will impact Puerto Rico today with rainfall totals of 1 to 3 inches with localized amounts of 5 inches possible. This rain may lead to isolated flash flooding, minor river flooding, and mudslides. Across portions of southern Hispaniola and Jamaica, rainfall of 4 to 8 inches with isolated maximum amounts of 15 inches is expected Saturday into Sunday. This rain may lead to scattered flash flooding and mudslides. Across portions of the Cayman Islands and Cuba Sunday into Monday, rainfall of 5 to 10 inches with isolated maximum amounts of 15 inches is expected. This will result in significant flash flooding with mudslides in Cuba. Rainfall from Elsa is likely to impact portions of the Florida Keys and southern Florida early next week. Amounts of 2 to 4 inches with localized maximum amounts up to 6 inches will be possible, which may result in isolated flash, urban, and minor river flooding. 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.
