DISCUSSION AND OUTLOOK ---------------------- At 600 AM MDT (1200 UTC), the center of Hurricane Genevieve was located near latitude 23.0 North, longitude 111.0 West. Genevieve is moving toward the northwest near 8 mph (13 km/h), and this motion is expected to continue through Saturday. On the forecast track, the center of Genevieve is expected to pass just to the southwest and west of the southern portion of the Baja California peninsula today, and move away from the peninsula on Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Further gradual weakening is expected today and through the weekend. However, Genevieve is forecast to remain a hurricane through today while it passes just to the southwest and west of the southern Baja California peninsula. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). An automated observing site near the Cabo San Lucas Marina recently reported a wind gust to 72 mph (116 km/h). The estimated minimum central pressure is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions will continue for the next few hours in the warning area. Tropical storm conditions will spread northward within the warning area in the southern Baja California peninsula through today. Tropical storm conditions are possible within the watch area later this morning, especially over higher terrain. RAINFALL: Genevieve is expected to produce rainfall amounts of 4 to 8 inches with isolated totals of 12 inches across portions of far southern Baja California Sur. This rainfall may lead to life-threatening flash flooding and mudslides. SURF: Large swells produced by Genevieve are affecting portions of the west-central coast of Mexico and are spreading northward along the coast of the Baja California peninsula. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
