DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Leslie was located near latitude 32.3 North, longitude 29.8 West. Leslie is moving toward the east-northeast near 29 mph (46 km/h). A continued east- northeastward motion with an increase in forward speed is expected through Friday. Leslie is then forecast to slow down and turn toward the east or east-southeast by Saturday. On the forecast track, Leslie will pass near Madeira Island by late Saturday. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Weakening is forecast during the next 72 hours, and Leslie could transition into a post-tropical low by Sunday or Sunday night. Hurricane-force winds extend outward up to 75 miles (120 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 969 mb (28.62 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected on Madeira Island beginning early Saturday. RAINFALL: Leslie is expected to produce total rain accumulations of 1 to 4 inches across Madeira Island through Sunday. This could lead to flash flooding and mudslides in mountainous terrain. SURF: Swells generated by Leslie will likely affect portions of the Azores, Madeira Island and the Canary Islands through Saturday and could reach the Atlantic coasts of Spain, Portugal, and Morocco over the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
