DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 100 AM CDT (0600 UTC), the center of Hurricane Katia was located near latitude 21.6 North, longitude 94.7 West. Katia is drifting toward the east-southeast near 2 mph (4 km/h). Little overall motion is anticipated through late today, but then the hurricane is forecast to turn southwestward and approach the coast within the watch area late Friday or early Saturday. Maximum sustained winds remain near 80 mph (130 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours and Katia could be near major hurricane strength at landfall. Katia is a small tropical cyclone. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm- force winds extend outward up to 45 miles (75 km). The estimated minimum central pressure is 989 mb (29.21 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 along the immediate coast within portions of the hurricane watch area. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Katia is expected to produce total rain accumulations of 5 to 10 inches over northern Veracruz, and 2 to 5 inches over far southern Tamaulipas, northeast Puebla, and southern Veracruz through Saturday morning. Isolated maximum amounts of 15 inches are possible in northern Veracruz. This rainfall may cause life-threatening flash floods and mudslides, especially in areas of mountainous terrain. WIND: Hurricane conditions are possible within the watch area by late Friday, with tropical storm conditions possible early Friday. SURF: Swells generated by Katia are expected to affect portions of the coast of southeastern Mexico today. These swells are likely to cause life-threatening surf and rip current conditions.
