DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM AST (1500 UTC), the center of Hurricane Alex was located near latitude 31.5 North, longitude 28.4 West. Alex is moving toward the north-northeast near 20 mph (31 km/h) and a turn toward the north with an increase in forward speed is expected over the next day or two. On the forecast track, the center of Alex will move near or over portions of the Azores Friday morning. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is forecast through Friday. Hurricane force winds extend outward up to 25 miles (35 km) from the center and tropical storm force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 981 mb (28.97 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical-storm-force winds are expected to begin over portions of the Azores tonight. Hurricane conditions are expected to spread over the central Azores by early Friday. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater. RAINFALL: Alex is expected to produce total rain accumulations of 3 to 5 inches over the Azores through Friday, with possible isolated maximum amounts of 7 inches. These rains could produce life-threatening flash floods and mud slides. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of the center of Alex. Near the coast, the surge will be accompanied by large and destructive waves. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST. Next complete advisory at 500 PM AST. $$ Forecaster Pasch
