SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Manzanillo to Altata Mexico A Hurricane Watch is in effect for... * North of Altata to Topolobampo Mexico A Tropical Storm Warning is in effect for... * South of Manzanillo to Lazaro Cardenas Mexico A Tropical Storm Watch is in effect for... * Cabo San Lucas to La Paz Mexico A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the coasts of Sinaloa, Sonora, and Baja California Sur should monitor the progress of Nora. Additional watches and warnings may be required for portions of these areas tonight or on Sunday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Hurricane Nora was located near latitude 19.7 North, longitude 105.4 West. Nora is moving toward the north near 14 mph (22 km/h). A turn toward the north-northwest is expected tonight and on Sunday, followed by a slower northwestward motion Sunday night through Tuesday. On the forecast track, the center of Nora will move near or over western Jalisco during the next few hours, and then move over the Gulf of California near or along the coasts of Nayarit and Sinaloa tonight through Tuesday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is forecast during the next few days if Nora's center remains over the waters of the Gulf of California. However, weakening would likely occur if the center moves inland. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 160 miles (260 km). A sustained wind of 77 mph (124 km/h) was recently reported at Chamela-Cuixmala, Jalisco. The estimated minimum central pressure is 977 mb (28.85 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nora can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Hurricane conditions are occurring within the southern portion of the hurricane warning area and are likely to spread northward within hurricane warning area through Monday. Hurricane conditions are also possible within the hurricane watch area late Monday. Tropical storm conditions will continue over the tropical storm warning area through tonight. Tropical storm conditions are possible within the tropical storm watch area in Baja California Sur on Monday. RAINFALL: Nora is expected to produce rainfall totals of 8 to 12 inches with maximum amounts of 20 inches this weekend into early next week along the west coast of Mexico from the Mexican states of Guerrero northward to southern Sonora, including Baja California Sur. This rainfall will produce life-threatening flash flooding and mudslides. Toward the middle and latter part of next week, moisture associated with Nora may bring heavy rainfall to portions of the southwestern U.S. and central Rockies. STORM SURGE: Storm surge is expected to produce significant coastal flooding in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Nora are affecting the southern and southwestern coast of Mexico and will spread northward to the coast of Baja California Sur and into the Gulf of California into early next week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 700 PM CDT. Next complete advisory at 1000 PM CDT. $$ Forecaster Berg
