A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the eye of Hurricane Gabrielle was located near latitude 33.9 North, longitude 58.3 West. Gabrielle is moving toward the east-northeast near 20 mph (31 km/h). A faster east-northeastward motion is expected through Thursday. On the forecast track, the center of Gabrielle will continue to move away from Bermuda today, but begin approaching the Azores on Thursday. Maximum sustained winds remain near 140 mph (220 km/h) with higher gusts. Gabrielle is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Gradual weakening is expected during the next couple of days. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The estimated minimum central pressure is 948 mb (28.00 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Gabrielle can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. WIND: Hurricane conditions are possible within the watch area by Thursday night. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near the areas of onshore winds where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: From Thursday into Friday morning, Gabrielle may bring 3 to 5 inches or 75 to 125 mm of rainfall across the central and western Azores. During the same time outer bands from Gabrielle may also result in 1 to 2 inches or 25 to 50 mm of rain across the eastern Azores. SURF: Swells generated by Gabrielle will continue to affect Bermuda, the U.S. East Coast from North Carolina northward, and Atlantic Canada over the next few days. These swells are expected to produce life-threatening surf and rip current conditions. Please consult products issued by your local weather office.
