DISCUSSION AND OUTLOOK ---------------------- At 100 AM EST (0600 UTC), the eye of Hurricane Rafael was located by an Air Force Hurricane Hunter aircraft and Grand Cayman radar near latitude 20.2 North, longitude 80.9 West. Rafael is moving toward the northwest near 13 mph (20 km/h). A general northwestward motion is anticipated over the next day or so, followed by a gradual west-northwestward turn in the Gulf of Mexico. On the forecast track, Rafael is expected move over western Cuba later today, and move into the southeastern Gulf of Mexico tonight. Maximum sustained winds have increased to near 85 mph (140 km/h) with higher gusts. Rapid strengthening is forecast, and Rafael is forecast to become a Category 2 hurricane before it makes landfall in Cuba later today. Rafael could briefly weaken over Cuba but is then expected to emerge into the southeastern Gulf of Mexico as a hurricane. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km). The minimum central pressure estimated from Air Force Hurricane Hunter aircraft observations is 977 mb (28.85 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Hurricane 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 portions of the Cayman Islands for the next few hours and are also expected in western Cuba and the Isle of Youth today. Tropical storm conditions are expected in parts of west-central Cuba and the lower and middle Florida Keys today and tonight. Tropical storm conditions are possible farther east in central Cuba today. 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 https://www.nhc.noaa.gov/graphics_at3.shtml?rainqpf STORM SURGE: Storm surge could raise water levels by 1 to 3 feet above normal tide levels in the Cayman Islands tonight, 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 on Wednesday. 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 today over the Florida Keys and far southwestern Florida mainland. SURF: Swells generated by Rafael are expected to affect much of the western Caribbean during the next few days and will also spread across most of the Gulf of Mexico from east to west late this week into the early part of the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
