DISCUSSION AND OUTLOOK ---------------------- At 900 AM GMT (0900 UTC), the center of Hurricane Gabrielle was located near latitude 36.5 North, longitude 38.8 West. Gabrielle is moving toward the east near 32 mph (52 km/h). A fast eastward to east-northeastward motion is expected during 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 today and move across the island chain tonight into early Friday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Gabrielle is forecast to be at hurricane strength when it passes through the Azores. After that, it is expected to weaken as it becomes an extratropical low. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). The estimated minimum central pressure is 979 mb (28.91 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 tonight into early Friday, with tropical storm conditions likely by this evening. Significant hurricane-force wind gusts are likely across portions of the Azores even after the center passes. 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 tonight through Friday morning, Gabrielle could produce up to 3 to 5 inches, 75 to 125 mm, of storm total rainfall across the central Azores. This rainfall could produce flash flooding within their mountains. Elsewhere, Gabrielle is expected to yield 1 to 3 inches or 25 to 75 mm of rain across the western and 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. Swells from Gabrielle will begin reaching the Azores later today. These swells are expected to produce life-threatening surf and rip current conditions.
