DISCUSSION AND OUTLOOK ---------------------- At 100 PM EST (1800 UTC), the center of Tropical Storm Rafael was located near latitude 18.6 North, longitude 79.1 West. Rafael is moving toward the northwest near 14 mph (23 km/h). A generally northwestward motion is anticipated over the next few days. On the forecast track, the storm is expected to move away from western Jamaica this afternoon, and be near or over the Cayman Islands this evening and tonight, and be near or over western Cuba on Wednesday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Steady to rapid intensification is expected during the next 24 to 36 hours, and Rafael is expected to become a hurricane as it passes near the Cayman Islands with further strengthening before it makes landfall in Cuba. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The minimum central pressure recently reported by an Air Force Reserve Hurricane Hunter aircraft is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Rafael can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC and on the web at hurricanes.gov/text/MIATCDAT3.shtml WIND: Hurricane conditions are expected in the Cayman Islands by this evening and are also expected in western Cuba and the Isle of Youth on Wednesday. Tropical storm conditions are expected in Jamaica for several more hours and are expected in parts of west-central Cuba and the lower and middle Florida Keys on Wednesday and Wednesday night. Tropical Storm conditions are possible farther east in central Cuba on Wednesday. RAINFALL: Heavy rainfall will impact areas of the Western Caribbean through early Thursday, particularly across Jamaica and the Cayman Islands into southern and western portions of Cuba. Rainfall totals between 3 to 6 inches are expected, with isolated higher totals up to 10 inches anticipated across areas of higher terrain, which could lead to areas of flash flooding and mudslides. Rainfall totals of 1 to 3 inches are expected for the Lower and Middle Florida Keys. For a complete depiction of forecast rainfall associated with Tropical Storm Rafael, please see the National Weather Service Storm Total Rainfall Graphic, available at POST-TROPICAL CYCLONE RAFAEL STORM SURGE: Minor coastal flooding is possible in Jamaica tonight. Storm surge could raise water levels by 1 to 3 feet above normal tide levels in the Cayman Islands on Tuesday, and could raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore winds along the southern coast of Cuba in the Hurricane Warning area, including the Isle of Youth. The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Dry Tortugas...1-3 ft Lower Florida Keys...1-2 ft TORNADOES: A few tornadoes are possible Wednesday over the Keys and southwesternmost Florida mainland. SURF: Swells generated by Rafael are expected to affect much of the western Caribbean during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
