DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 900 PM MDT (0300 UTC), the center of Tropical Storm Blanca was located near latitude 22.3 North, longitude 111.2 West. Blanca is moving toward the north-northwest near 10 mph (17 km/h), and this general motion is expected to continue during the next day or two. On the forecast track, the center of Blanca will approach the southwestern coast of the Baja California peninsula overnight, and move near or over the peninsula Monday through Tuesday. Maximum sustained winds have decreased to near 65 mph (100 km/h), with higher gusts. Additional weakening is forecast, and Blanca is expected to become to a tropical depression by Monday afternoon or evening. Blanca will likely dissipate near or over northern portions of the Baja California peninsula by late Tuesday. Tropical storm force winds extend outward up to 150 miles (240 km) from the center. The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are occurring over far southern portions of the Baja California peninsula and should spread northward within the warning area tonight and Monday. Tropical storm conditions are possible within the watch area on Monday. 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 may begin to affect portions of the southwestern United States on Tuesday. 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 will likely cause life-threatening surf and rip currents. For additional information, please consult products from your local weather office.
