DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM EDT (1500 UTC), the eye of Hurricane Irma was located by a reconnaissance plane and radar near latitude 22.8 North, longitude 79.8 West. Irma is moving toward the west along the north coast of Cuba at near 9 mph (15 km/h). A northwest motion is expected to begin later today with a turn toward the north- northwest on Sunday. On the forecast track, the core of Irma will continue to move near or over the north coast of Cuba later today, and will reach the Florida Keys Sunday morning. The hurricane is expected to move along or near the southwest coast of Florida Sunday afternoon.
Maximum sustained winds are near 125 mph (205 km/h) with higher gusts. Irma is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Irma is forecast to restrengthen once it moves away from Cuba, and Irma is expected to remain a powerful hurricane as it approaches Florida.
Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). Caibarien, Cuba recently reported a wind gust to 124 mph (200 km/h).
The minimum central pressure reported by an Air Force plane was 941 mb (27.79 inches).
HAZARDS AFFECTING LAND ---------------------- STORM SURGE: The combination of a dangerous 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 is expected to reach the following HEIGHTS ABOVE GROUND if the peak surge occurs at the time of high tide...
Cape Sable to Captiva...10 to 15 ft Captiva to Ana Maria Island...6 to 10 ft Card Sound Bridge through Cape Sable, including the Florida Keys...5 to 10 ft Ana Maria Island to Clearwater Beach, including Tampa Bay...5 to 8 ft North Miami Beach to Card Sound Bridge, including Biscayne Bay...4 to 6 ft Isle of Palms, South Carolina to Fernandina Beach...4 to 6 ft Clearwater Beach to Ochlockonee River...4 to 6 ft Fernandina Beach to North Miami Beach...2 to 4 ft
The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.
The combination of a life-threatening storm surge and large breaking waves will raise water levels ABOVE NORMAL TIDE LEVELS by the following amounts within the hurricane warning area near and to the north of the center of Irma. Near the coast, the surge will be accompanied by large and destructive waves.
Ragged Island in the Bahamas...15 to 20 ft Central and Northwestern Bahamas...3 to 6 ft Northern coast of Cuba in the warning area...5 to 10 ft
WIND: Hurricane conditions are expected to continue within the hurricane warning area along the north coast of Cuba through today. Hurricane conditions are expected in portions of the northwestern Bahamas today, and in portions of the Florida peninsula and the Florida Keys tonight and Sunday.
Hurricane and tropical storm conditions are possible within the watch area on Sunday.
RAINFALL: Irma is expected to produce the following rain accumulations through Wednesday: Northern Cuba...10 to 15 inches, isolated 20 inches. Southern Cuba...5 to 10 inches, isolated 15 inches. Western Bahamas...3 to 6 inches, isolated 10 inches. The Florida Keys...10 to 20 inches, isolated 25 inches. The Florida peninsula and southeast Georgia...8 to 15 inches, isolated 20 inches. The eastern Florida Panhandle...3 to 6 inches, isolated 8 inches. Rest of eastern Georgia, western South Carolina, and western North Carolina...4 to 8 inches. Western Georgia, eastern and northern Alabama, and southern Tennessee...2 to 5 inches. In all areas this rainfall may cause life-threatening flash floods and, in some areas, mudslides.
TORNADOES: A few tornadoes are possible today and tonight over southern Florida.
SURF: Swells generated by Irma are affecting the southeastern Bahamas, the Turks and Caicos Islands and the southeast coast of the United States today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
