SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Baffin Bay to High Island Texas A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 AM CDT (1200 UTC), the center of Tropical Storm Bill was located near latitude 28.2 North, longitude 96.0 West. Bill is moving toward the northwest near 13 mph (20 km/h) and this general motion is expected to continue today. On the forecast track, the center of Bill is expected to make landfall in the warning area along the Texas coast later this morning and move inland over south-central Texas this afternoon and tonight. Reports from an Air Force Reserve reconnaissance aircraft indicate that maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Little additional strengthening is expected before landfall occurs in a few hours. Weakening is forecast after the center moves inland later today, and Bill is expected to weaken to a tropical depression tonight. Tropical-storm-force winds extend outward up to 150 miles (240 km) from the center. During the past hour, a WeatherFlow observing station at Matagorda Bay reported a wind gust to 45 mph (72 km/h). The estimated minimum central pressure based on reconnaissance data is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Bill is expected to produce total rain accumulations of 4 to 8 inches over eastern Texas and eastern Oklahoma and 2 to 4 inches over western Arkansas and southern Missouri, with possible isolated maximum amounts of 12 inches in eastern Texas. WIND: Tropical storm conditions are expected to reach the coast within the warning area within the next hour or two. STORM SURGE: The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters. The water could reach the following heights above ground if the peak surge occurs at the time of high tide... Upper Texas coast...2 to 4 feet Western Louisiana coast...1 to 2 feet The deepest water will occur along the immediate coast near and to the right of the landfall location. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. TORNADOES: A few tornadoes will be possible across portions of eastern Texas and far western Louisiana today and tonight.
