Hazards affecting land

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 forecast of 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.

Wind. Tropical storm conditions are possible within the watch area and expected within the warning area later today.

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 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.

Tornado. A tornado or two is possible tonight through tonight from the Upper Texas Coast into southern Louisiana, Mississippi, Alabama,

And the western Florida Panhandle.
