DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Storm Dolores was located near latitude 16.3 North, longitude 102.8 West. Dolores is moving toward the northwest near 9 mph (15 km/h). A motion toward the northwest and then north-northwest at a increasing forward speed is expected tonight through early Sunday. On the forecast track, the center of Dolores is expected to cross the coast of southwestern or west-central Mexico within the warning area Saturday afternoon. Dolores is then expected to move north-northwestward just inland of the west-central coast of Mexico through early Sunday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Additional strengthening is expected until Dolores makes landfall Saturday afternoon. Rapid weakening is forecast thereafter, and Dolores should dissipate inland by Sunday morning. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Dolores can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at www.hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Tropical storm conditions are expected to first reach the coast within the warning later tonight or on Saturday, making outside preparations difficult or dangerous. Hurricane conditions are also possible within the hurricane watch area by Saturday afternoon. Tropical storm conditions are possible within the tropical storm watch area Saturday night into Sunday morning. RAINFALL: Dolores will produce heavy rains over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, Jalisco, and Nayarit during the next few days, with rainfall totals of 6 to 10 inches expected with isolated maximum amounts of 15 inches possible. As a result, life-threatening flash flooding and mudslides may occur. STORM SURGE: A storm surge is expected to produce coastal flooding near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Dolores will affect portions of the southwestern coast of Mexico through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
