The system is moving toward the northeast near 6 mph (9 km/h), and this general motion with an increase in forward speed is anticipated over the next couple of days. The disturbance should move offshore the Texas coast tonight, move roughly parallel to the upper Texas coast on Wednesday and move back inland in extreme eastern Texas or southwestern Louisiana late Wednesday or early Thursday. Maximum sustained winds remain near 30 mph (45 km/h) with higher gusts. The disturbance is forecast to gradually strengthen and could become a tropical storm early on Wednesday.

HAZARDS AFFECTING LAND ---------------------- Key messages for Potential Tropical Cyclone One can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC. RAINFALL: Potential Tropical Cyclone One is expected to produce rainfall totals of 5 to 10 inches, with isolated higher totals near 20 inches, through Thursday from the Mid and Upper Texas coast east-northeast into southern and central portions of Louisiana, Mississippi, and Alabama, along with western portions of Georgia and the Florida Panhandle. This could generate dangerous to life-threatening flash flooding. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone One, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at1.shtml?ero For a list of rainfall observations (and wind reports) associated this potential tropical cyclone, see the companion storm summary at WBCSCCNS1 with the WMO header ACUS44 KWBC or at the following link: www.wpc.ncep.noaa.gov/discussions/nfdscc1.html WIND: Tropical storm conditions are possible within the watch area beginning early Wednesday and within the warning area on Wednesday morning. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Port Bolivar, TX to Morgan City, LA...2-4 ft The deepest water will occur along the immediate coast near and to the east of the landfall location, where the surge will be accompanied by large and dangerous waves. 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. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at1.shtml?peakSurge. SURF: Swells generated by the Potential Tropical Cyclone are likely to cause life-threatening surf and rip current conditions along the northwestern Gulf Coast for the next couple of days. Please consult products from your local weather office. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at1.shtml?ripCurrents TORNADO: A tornado or two is possible tonight and tomorrow from the Upper Texas coast across southern Louisiana, Mississippi, Alabama and the Florida Panhandle.
