For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 PM CDT (0000 UTC), the center of Hurricane Katia was located near latitude 20.9 North, longitude 96.8 West. Katia is moving toward the west-southwest near 7 mph (11 km/h) and this motion is expected to continue through Saturday. The center of Katia will make landfall in Mexico late tonight or early Saturday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Little change in strength is expected prior to landfall, followed by rapid weakening thereafter. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The estimated minimum central pressure is 972 mb (28.71 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: A dangerous storm surge will raise water levels by as much as 5 to 8 feet above normal tide levels near and to the north of where Katia makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Katia is expected to produce total rain accumulations of 10 to 15 inches over northern Veracruz, eastern Hidalgo, and Puebla. Katia is also expected to produce total rain accumulations of 2 to 5 inches over southern Tamaulipas, eastern San Luis Potosi, western Hidalgo, eastern Queretaro, and southern Veracruz through Saturday evening. Isolated maximum amounts of 25 inches are possible in northern Veracruz, eastern Hidalgo, Puebla, and San Luis Potosi. This rainfall will likely cause life-threatening flash floods and mudslides, especially in areas of mountainous terrain. WIND: Hurricane conditions are expected within portions of the hurricane warning area tonight or early Saturday, with tropical storm conditions expected to continue within the tropical storm warning areas. SURF: Swells generated by Katia will continue to affect portions of the coast of southeastern Mexico during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
