DISCUSSION AND OUTLOOK ---------------------- At 1200 AM GMT (0000 UTC), the center of Post-Tropical Cyclone Gabrielle was located near latitude 37.6 North, longitude 30.5 West. The post-tropical cyclone is moving toward the east-northeast near 30 mph (48 km/h). An eastward to east-northeastward motion with a gradual decrease in forward speed is expected through Saturday, followed by a turn toward the southeast through early next week. On the forecast track, the center of post-tropical Gabrielle will move across the Azores this morning, then approach the coast of Portugal by early Sunday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Gabrielle is forecast to be at or near hurricane strength when it passes through the Azores. Then, weakening is expected over the weekend and into early next week. Gale-force winds extend outward up to 185 miles (295 km) from the center. Horta on Faial Island in the central Azores recently reported a wind gust to 43 mph (69 km/h). The estimated minimum central pressure is 983 mb (29.03 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, especially in gusts, are expected in the Azores this morning, with tropical storm conditions expected to spread across the islands during the next couple of hours. 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: Through this 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 the mountains. Elsewhere, Gabrielle is expected to yield 1 to 3 inches, 25 to 75 mm, of rain across the western and eastern Azores. SURF: Swells generated by Gabrielle will affect the Azores through the weekend. Swells from Gabrielle will reach the coast 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.
