DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1200 AM MDT (0600 UTC), the eye of Hurricane Blanca was located near latitude 19.4 North, longitude 110.6 West. Blanca is moving toward the north-northwest near 10 mph (17 km/h), and this motion with a slight increase in forward speed is expected through late Monday. On the forecast track, the center of Blanca is expected to approach the southwestern coast of the Baja California peninsula on Sunday and move near or along the coast on Monday. Maximum sustained winds have decreased to near 115 mph (185 km/h) with higher gusts. Blanca is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional weakening is forecast through late Monday, and Blanca should become a tropical storm by Sunday night before it reaches the southwestern coast of the Baja California peninsula. Hurricane force winds extend outward up to 60 miles (95 km) from the center, and tropical storm force winds extend outward up to 175 miles (280 km). An automated station on Socorro Island recently reported sustained winds of 74 mph (118 km/h) and a wind gust of 101 mph (162 km/h). The estimated minimum central pressure is 956 mb (28.23 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the warning area on Sunday, making outside preparations difficult or dangerous. Hurricane conditions are possible in the hurricane watch area on Sunday. Tropical storm conditions are possible within the tropical storm watch area starting Sunday night. RAINFALL: Blanca is expected to produce total rain accumulations of 6 to 10 inches over much of Baja California Sur and the southern portion of the state of Baja California, with possible isolated maximum amounts of 15 inches over Baja California Sur. These rains could produce life-threatening flash floods and mudslides. SURF: Swells generated by Blanca are affecting the coast of southwestern Mexico, the Pacific coast of the Baja California peninsula, and the southern Gulf of California. These swells are likely to cause life-threatening surf and rip current conditions. For additional information, please consult products from your local weather office.
