DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 PM CDT (2100 UTC), the center of Hurricane Patricia was located near latitude 18.9 North, longitude 105.2 West. Patricia is moving toward the north-northeast near 14 mph (22 km/h) and this motion is expected to continue with some increase in forward speed tonight and Saturday. On the forecast track, the center of Patricia should make landfall during the next several hours on the coast of Mexico between Manzanillo and Cabo Corrientes. After landfall, the center of Patricia is expected to move quickly north-northeastward across western and northern Mexico. Reports from a NOAA Hurricane Hunter aircraft indicate that Patricia has weakened a little during the past few hours and that maximum sustained winds are near 190 mph (305 km/h) with higher gusts. Patricia is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Patricia is expected to remain an extremely dangerous category 5 hurricane through landfall. After landfall, Patricia is forecast to rapidly weaken over the mountains of Mexico. Hurricane force winds extend outward up to 35 miles (55 km) from the center and tropical storm force winds extend outward up to 175 miles (280 km). The minimum central pressure from the NOAA Hurricane Hunter Data is 900 mb (26.58 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions should spread across the hurricane warning area during the next few hours, with the worst conditions occurring near where the eye of Patricia makes landfall. Tropical storm conditions are spreading across portions of the warning area. Preparations to protect life and property should be rushed to completion. Hurricane conditions are possible in the hurricane watch area this afternoon and this evening. RAINFALL: Patricia is expected to produce total rainfall accumulations of 8 to 12 inches, with isolated maximum amounts of 20 inches, over the Mexican states of Nayarit, Jalisco, Colima, Michoacan, and Guerrero through Saturday. These rains could produce life-threatening flash floods and mud slides. STORM SURGE: An extremely dangerous storm surge is expected to produce significant coastal flooding near and to the right of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Patricia are already affecting portions of the southern coast of Mexico, and will spread northwestward during 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.
