DISCUSSION AND OUTLOOK ---------------------- At 800 PM AST (0000 UTC), the center of Hurricane Leslie was located near latitude 34.4 North, longitude 22.4 West. Leslie is moving toward the east-northeast near 35 mph (56 km/h). A fast motion toward the east-northeast is expected to continue through Saturday, followed by a slower east-northeastward motion Saturday night and Sunday. On the forecast track, the center of Leslie will pass north of Madeira Island tonight and early Saturday, approach the southwestern portion of the Iberian Peninsula on Saturday, and move inland over portions of the Iberian Peninsula late Saturday and Sunday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Leslie is expected to transition into a hurricane-force post-tropical cyclone on Saturday. Weakening is forecast after Leslie moves inland over the Iberian Peninsula, and the post- tropical cyclone is expected to dissipate by Monday. Hurricane-force winds extend outward up to 70 miles (110 km), mainly to the south of the center. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. The estimated minimum central pressure is 972 mb (28.70 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected on Madeira Island early Saturday. Post-tropical Leslie will bring winds to near hurricane-force to portions of Portugal late Saturday, and tropical-storm-force winds to portions of western Spain late Saturday and Saturday night. Please see products from your local meteorological service for more information on this hazard. RAINFALL: Leslie is expected to produce total rain amounts of 1 to 3 inches (25 to 75 mm) with localized amounts up to 4 inches (100 mm) across Portugal and portions of Spain through Sunday night. This rainfall may lead to some instances of flash flooding. SURF: Swells generated by Leslie will likely affect portions of the Azores, Madeira Island, and the Canary Islands through Saturday and will 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.
