DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 AM CDT (1200 UTC), the center of Hurricane Katia was located near latitude 21.1 North, longitude 95.6 West. Katia is moving toward the west-southwest near 3 mph (6 km/h) and this general motion is expected to continue until the system makes landfall within the hurricane warning area by early Saturday. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Some additional strengthening is forecast during the next day or so and Katia could be near major hurricane strength at landfall. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 60 miles (95 km). The estimated minimum central pressure is 977 mb (28.85 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: A dangerous storm surge will raise water levels by as much as 5 to 7 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 may 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 by tonight or early Saturday, with tropical storm conditions expected within the tropical storm warning areas by later today. 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.
