DISCUSSION AND OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Hurricane Orlene was located near latitude 22.9 North, longitude 105.7 West. Orlene is moving toward the north-northeast near 10 mph (17 km/h), and this general motion should continue over the next day or so. On the forecast track, the center of Orlene will move farther inland over southwestern Mexico today and tonight. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Rapid weakening is expected during the next 12 to 24 hours as Orlene moves inland. Orlene is forecast to weaken to a tropical storm by this afternoon, and dissipate tonight or early Tuesday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 983 mb (29.03 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane and tropical storm conditions are expected in the warning areas along the coast of mainland Mexico through this afternoon. RAINFALL: Orlene is expected to produce the following rainfall across portions of Southwest Mexico through Tuesday: Northern Nayarit and southern Sinaloa: 3 to 6 inches with local amounts of 10 inches. Southwest Durango: 1 to 3 inches with local amounts of 5 inches. These rainfall amounts should lead to flash flooding, as well as possible landslides in areas of rugged terrain. STORM SURGE: A dangerous storm surge is likely to cause coastal flooding along the coast of mainland Mexico in the warning area in regions of onshore winds through early this afternoon. SURF: Large swells generated by Orlene will affect the southwestern coast of Mexico, southern portions of the Baja California peninsula and the Gulf of California over the next day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
