Preparations to protect life and property should be rushed to completion. 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 center of Hurricane Gabrielle was located near latitude 36.0 North, longitude 48.7 West. Gabrielle is moving toward the east-northeast near 25 mph (41 km/h). This general motion with some increase in forward speed is expected to continue for the next couple of days, followed by a slower eastward to east-southeastward motion this weekend. On the forecast track, the center of Gabrielle will approach the Azores during the day on Thursday, and move across the island chain Thursday night into Friday. Maximum sustained winds are near 110 mph (175 km/h) with higher gusts. Some weakening is expected during the next couple of days, but Gabrielle is still forecast to be a hurricane when it passes through the Azores. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 962 mb (28.41 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 expected in the Azores Thursday night and Friday, with tropical storm conditions likely by Thursday evening. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding in areas of onshore winds in the Azores. 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 over the next couple of days, and the U.S. East Coast from North Carolina northward and Atlantic Canada over the next day or so. These swells are expected to produce life-threatening surf and rip current conditions. Please consult products issued by your local weather office.
