A Tropical Storm Watch means that tropical storm conditions are possible within the watch area.

DISCUSSION AND OUTLOOK ---------------------- At 900 AM MDT (1500 UTC), the center of Hurricane Genevieve was located near latitude 23.3 North, longitude 111.4 West. Genevieve is moving toward the northwest near 12 mph (19 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 75 mph (120 km/h) with higher gusts. Further gradual weakening is expected today and through the weekend. However, Genevieve is expected to remain a hurricane through much of 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 115 miles (185 km). An automated observing site near the Cabo San Lucas Marina recently reported a wind gust to 46 mph (74 km/h). The estimated minimum central pressure is 984 mb (29.06 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will spread northward within the warning area in the southern Baja California peninsula through today and may linger into tonight. Tropical storm conditions are possible within the watch area through the early afternoon, especially over higher terrain. RAINFALL: Genevieve is expected to produce additional rainfall amounts of 2 to 4 inches across southern Baja California Sur, with isolated storm totals of 12 inches across 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.
