A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere along the west-central coast of Mexico and southern portions of Baja California Sur should monitor the progress of Nora. Additional watches and warnings will likely be required for portions of these areas later tonight and on Friday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Storm Nora was located near latitude 13.7 North, longitude 102.2 West. Nora is moving toward the west-northwest near 11 mph (18 km/h). A motion toward the northwest and north-northwest is expected to begin later tonight and continue through Sunday. On the forecast track, the center of Nora will approach the southwestern coast of Mexico Friday and Friday night and be very near the coast Saturday and Saturday night. Nora will then approach the southern portion of Baja California Sur on Sunday. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Strengthening is forecast during the next few days, and Nora is expected to become a hurricane on Saturday. Nora is a large tropical storm. Tropical-storm-force winds extend outward up to 205 miles (330 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 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 possible within the hurricane watch area Saturday, with tropical storm conditions beginning on Friday. Tropical storm conditions are expected within the tropical storm warning area beginning later tonight or on Friday. RAINFALL: Nora is expected to produce heavy rains over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, and Jalisco. Rainfall totals of 8 to 12 inches are forecast through this weekend with isolated maximum amounts of 20 inches possible. As a result, life-threatening flash flooding and mudslides may occur. SURF: Swells generated by Nora are affecting the southern coast of Mexico and will spread northward to the southwestern coast of Mexico through the end of the week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
