DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 900 AM MDT (1500 UTC), the center of Hurricane Blanca was located near latitude 20.5 North, longitude 111.0 West. Blanca is moving toward the north-northwest near 12 mph (19 km/h) and this general motion with a slight increase in forward speed is expected over the next couple of days. On the forecast track, the center of Blanca will approach the southwest coast of the Baja California peninsula later today, and move near or along the coast tonight and Monday. Maximum sustained winds have decreased near 90 mph (150 km/h) with higher gusts. Additional weakening is forecast during the next 48 hours, and Blanca is expected to weaken to a tropical storm tonight before it reaches the southwestern coast of the Baja California peninsula. Blanca is forecast to weaken to a tropical depression by Monday evening. Hurricane force winds extend outward up to 60 miles (95 km) from the center and tropical storm force winds extend outward up to 195 miles (315 km). The estimated minimum central pressure is 974 mb (28.77 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the southern portion of the warning area within a few hours, making outside preparations difficult or dangerous. Tropical storm conditions will then spread northward elsewhere within the warning area later today and Monday. Hurricane conditions are possible in the hurricane watch area later today and tonight. RAINFALL: Blanca is expected to produce total rain accumulations of 6 to 10 inches over much of Baja California Sur and the southern half 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 mud slides. 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.
