---------------------- 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 Wednesday across parts

of Deep South into southeast Texas. SURF: Swells generated by the disturbance will affect the coast of

Texas and northeastern Mexico through early Thursday. These swells are likely to cause life-threatening surf and rip current

conditions. Please consult products from your local weather office. NEXT ADVISORY
