For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 600 PM MDT (0000 UTC), the center of Tropical Storm Lidia was located near latitude 26.0 North, longitude 112.2 West. Lidia is moving toward the northwest near 12 mph (19 km/h), and this general motion is expected to continue for the next 48 hours. On the forecast track, the center of Lidia will move near or along the west coast of the Baja California peninsula through Saturday, and then move west of the peninsula over the Pacific Ocean by Sunday morning. Maximum sustained winds have decreased to near 50 mph (80 km/h) with higher gusts. Weakening is forecast during the next couple of days while Lidia interacts with the mountainous terrain of the Baja California peninsula and moves over cold Pacific waters. Lidia is expected to become a remnant low by Sunday. Tropical-storm-force winds extend outward up to 195 miles (315 km) mainly to the east of the center. The estimated minimum central pressure is 992 mb (29.30 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Lidia is expected to produce total rain accumulations of 6 to 12 inches across the Mexican states of Baja California Sur into Baja California, Sinaloa and the coastal section of Sonora, with isolated maximum amounts of 20 inches. These rains may cause life-threatening flash floods and mudslides. Some of the tropical moisture from Lidia may reach parts of the desert Southwest this holiday weekend, including southern California, southern Nevada and southwestern Arizona. WIND: Tropical storm conditions are occurring in the warning area over the southern and central portions of Baja California Sur and over portions of the Mexican mainland at this time. These conditions should spread northward across the warning areas of the Baja California peninsula and mainland Mexico through Saturday. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater. STORM SURGE: A dangerous storm surge is expected to produce coastal flooding in areas of onshore winds on the southern portion of Baja California Sur. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Lidia are affecting portions of the coast of southwestern and western Mexico and southern portions of Baja California Sur, and could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 900 PM MDT. $$ Forecaster Beven NNNN
