DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Hurricane Gabrielle was located near latitude 35.6 North, longitude 51.5 West. Gabrielle is moving toward the east-northeast near 25 mph (41 km/h), and this motion with some additional acceleration is expected to continue for the next several days. 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 115 mph (185 km/h) with higher gusts. Gabrielle is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Steady weakening is expected during the next couple of days, but Gabrielle is still expected 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 140 miles (220 km). The estimated minimum central pressure is 959 mb (28.32 inches).

WIND: Hurricane conditions are expected in the warning area Thursday night and Friday. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near the areas of onshore winds. 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.
