DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 300 AM MDT (0900 UTC), the center of Tropical Storm Blanca was located near latitude 23.8 North, longitude 111.5 West. Blanca is moving toward the north-northwest near 15 mph (24 km/h), and this general motion is expected to continue through Tuesday. On the forecast track the center of Blanca will move near or over portions of the southern and central Baja California peninsula today through Tuesday. Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Additional weakening is forecast, and Blanca is expected to weaken to a tropical depression by tonight. Blanca will likely dissipate near or over central or northern portions of the Baja California peninsula on Tuesday. Tropical storm force winds extend outward up to 150 miles (240 km) from the center. A wind gust to 40 mph (65 km/h) was recently reported at La Paz, Mexico. The estimated minimum central pressure is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue spreading northward in portions of the warning area today. Tropical storm conditions are possible within the watch area today. RAINFALL: Blanca is expected to produce total rain accumulations of 3 to 5 inches over much of Baja California Sur and the southern half of the state of Baja California, with isolated maximum amounts of 10 inches over Baja California Sur. These rains could produce life- threatening flash floods and mud slides. Rainfall associated with Blanca and its remnants could begin to affect portions of the southwestern United States on Tuesday. SURF: Swells generated by Blanca are affecting portions of the coast of southwestern Mexico, the Pacific coast of the Baja California peninsula, and the southern Gulf of California. These swells will likely cause life-threatening surf and rip currents. For additional information, please consult products from your local weather office.
