For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 900 AM MDT (1500 UTC), the center of Tropical Storm Lidia was located near latitude 27.9 North, longitude 114.3 West. Lidia is moving toward the northwest near 12 mph (19 km/h), and this motion is expected to continue through Sunday night. A turn toward the west-northwest is expected on Monday. On the forecast track, Lidia's center will emerge over the Pacific during the next few hours and then move away from the Baja California peninsula later today and tonight. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts, mainly over the Gulf of California to the east of the center. Additional weakening is forecast, and Lidia is expected to become a tropical depression later today and a remnant low pressure area tonight or Sunday. Tropical-storm-force winds extend outward up to 175 miles (280 km) to the east of the center. A Mexican automated station at Bahia de Los Angeles recently reported a wind gust of 48 mph (77 km/h). The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Lidia is expected to produce total rain accumulations of 4 to 8 inches across the Mexican states of Baja California Sur into Baja California and the coastal section of Sonora and northern Sinaloa, with isolated maximum amounts of 12 inches. These rains may cause life-threatening flash floods and mudslides. Some of the tropical moisture from Lidia will spread across parts of the desert Southwest through this holiday weekend for an increase in scattered showers and thunderstorms, from southern Nevada and western Arizona into southern California. WIND: Tropical storm conditions are occurring over portions of the warning area in the Mexican states of Baja California Sur, Baja California, and Sonora, especially near the coast of the Gulf of California. These conditions should persist for the next several hours. 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: Some coastal flooding is possible in areas of onshore winds along the Baja California peninsula. Near the coast, the surge will be accompanied by large waves. SURF: Swells generated by Lidia are affecting portions of the coast of western mainland Mexico and the west coast of Baja California Sur. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 1200 PM MDT. Next complete advisory at 300 PM MDT. $$ Forecaster Beven NNNN
