DISCUSSION AND OUTLOOK ---------------------- At 900 AM GMT (0900 UTC), the center of Post-Tropical Cyclone Gabrielle was located near latitude 39.1 North, longitude 26.1 West. The post-tropical cyclone is moving toward the east-northeast near 29 mph (46 km/h). An east-northeastward to eastward motion with a gradual decrease in forward speed is expected through Saturday, followed by a turn toward the southeast and south through early next week. On the forecast track, the center of post-tropical Gabrielle will start moving away from the Azores during the next few hours, then approach the coast of Portugal by early Sunday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Little change in strength is likely through tonight, but gradual weakening should begin on Saturday. Tropical-storm-force winds extend outward up to 160 miles (260 km) from the center. Pico Santos de Cima, in the mountains on Sao Miguel Island, recently reported sustained winds of 78 mph (125 km/h). Earlier, the observatory station in Horta on Faial Island reported a wind gust of 96 mph (154 km/h). The estimated minimum central pressure is 990 mb (29.24 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: Tropical storm conditions, with gusts to hurricane force, are occurring in the central and southeastern Azores. Hurricane-force winds are occurring in areas of elevated terrain. Strong, gusty winds will continue across these islands through the morning. Gusty winds are possible along portions of the coast of Portugal late Saturday through Sunday. 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: Gabrielle is expected to produce less than an inch, or 25 mm, of additional rainfall across the Azores today. Any flooding caused by Gabrielle across the terrain of the central Azores should subside today. SURF: Swells generated by Gabrielle will affect the Azores through the weekend and will reach the coasts of Portugal, northwestern Spain, and northern Morocco on Saturday. These swells are expected to produce life-threatening surf and rip current conditions. Please consult products issued by your local weather office.
