Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some increase in strength is likely during the next 36 hours, and the disturbance is forecast to become a tropical storm by Wednesday. * Formation chance through 48 hours...high...80 percent. * Formation chance through 7 days...high...80 percent. The disturbance is quite large, and satellite-derived wind data indicate that tropical-storm-force winds extend outward up to 415 miles (665 km) north of the center.

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 across northeast Mexico into South Texas, with maximum totals of 15 inches possible. This rainfall will likely produce flash and urban flooding along with new and renewed river flooding. Mudslides are also possible in areas of higher terrain across northeast Mexico. For a complete depiction of forecast rainfall and flash flooding 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 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... Sargent, TX to Sabine Pass, TX...2-4 ft Galveston Bay...2-4 ft Mouth of the Rio Grande, TX to Sargent, TX...1-3 ft Sabine Pass, TX to Vermilion/Cameron Parish Line, LA...1-3 ft The deepest water will occur along the immediate coast near and to the north 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. In Mexico, minor coastal flooding is possible north of where the center of the system crosses the coast in areas of onshore winds. WIND: Tropical storm conditions are expected within the warning area by tonight or Wednesday. TORNADOES: A couple of tornadoes may occur across parts of Deep South Texas on Wednesday. SURF: Swells generated by the disturbance will affect the coast of Texas and northeastern Mexico through Wednesday night. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
