DISCUSSION AND OUTLOOK ---------------------- At 1200 AM MDT (0600 UTC), the center of Hurricane Willa was located near latitude 20.6 North, longitude 107.3 West. Willa is moving toward the north near 9 mph (15 km/h). A turn toward the north- northeast is expected later this morning, followed by a faster motion toward the northeast by this evening. On the forecast track, the center of Willa will move near or over Las Islas Marias later this morning and afternoon and make landfall within the hurricane warning area along the west-central coast of mainland Mexico later afternoon or this evening. Maximum sustained winds have decreased to near 140 mph (225 km/h) with higher gusts. Willa is an extremely dangerous category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. While gradual weakening is forecast today, Willa is expected to be a dangerous major hurricane when it reaches the coast of Mexico. Rapid weakening is expected after landfall tonight and Wednesday. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The estimated minimum central pressure is 942 mb (27.82 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: An extremely dangerous storm surge is likely along portions of the coast of southwestern Mexico in southern Sinaloa and Nayarit, especially near and to the south of where the center of Willa makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Willa is expected to produce storm total rainfall accumulations of 6 to 12 inches, with local amounts to 18 inches, across portions of western Jalisco, western Nayarit, southern Sinaloa, and far southern Durango in Mexico. This rainfall will cause life-threatening flash flooding and landslides. Farther inland, Willa is expected to produce rainfall amount of 2 to 4 inches across the rest of Durango and portions of Zacateca, southeast Chihuahua, and Coahuila, with local amounts to 6 inches possible. This rainfall could cause life-threatening flash flooding. WIND: Hurricane conditions are expected within the hurricane warning area beginning this afternoon, with tropical storm conditions expected later this morning. Tropical storm conditions are expected within the tropical storm warning areas this morning and continuing into this afternoon. SURF: Large swells generated by Willa will continue to affect portions of the coast of southwestern and west-central Mexico during the next few days. Swells should begin to affect portions of the coast of the southern Baja California peninsula later today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 300 AM MDT. $$ Forecaster Stewart
