DISCUSSION AND OUTLOOK ---------------------- At 500 AM PDT (1200 UTC), the center of Tropical Storm Sergio was located near latitude 17.7 North, longitude 124.1 West. Sergio is moving toward the east-northeast near 12 mph (19 km/h). An east- northeastward to northeastward motion with a further increase in forward speed is expected during the next few days. On the forecast track, the center of Sergio will approach the Pacific coast of Baja California Sur early Friday. Maximum sustained winds remain near 70 mph (110 km/h) with higher gusts. Gradual weakening is forecast during the next several days. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 991 mb (29.27 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Through Sunday, heavy rainfall with Sergio is expected to lead to storm total accumulations of 3 to 5 inches with local amounts to 10 inches in northern Baja California Sur and Sonora in Mexico and well as the Southern Plains and the Ozarks of the United States. This rainfall could lead to life-threatening flash flooding and mudslides within mountainous terrain. SURF: Swells generated by Sergio will begin to affect much of the 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 800 AM PDT. $$ Forecaster Avila
