US: Adverse winter weather forecast over southern regions through at least Nov. 26
Adverse winter weather forecast across parts of the southern US through at least Nov. 26. Hazardous travel conditions likely.
Event
Adverse winter weather is forecast across parts of the southern US through at least Nov. 26. Cold air drawn in on the back of an upper low moving across the southern plains is forecast to bring snowfall to parts of central and eastern New Mexico, western Texas, and far southern Colorado. Snowfall accumulations of around 10-20 cm (4-8 inches) are possible in parts of the affected area through Nov. 25, with higher accumulations possible over higher ground. Heavy snow accompanied by strong winds will likely lead to hazardous driving conditions due to icy roads and reduced visibility.
Government Advisories
As of early Nov. 24, the National Weather Service (NWS) has issued winter storm warnings over parts of far northern, central, eastern, and southeastern New Mexico, western Texas, and far southern Colorado. A blizzard warning has been issued over parts of the Guadalupe and Delaware Mountains including the city of Pine Springs in western Texas. Winter storm watches have been issued for parts of southern New Mexico and western Texas and winter weather advisories for parts of southern Colorado and central New Mexico. Officials could update and possibly extend the coverage of weather alerts over the coming days.
Hazardous Conditions
Snow accumulations are likely across the affected area, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation are less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Blizzard conditions are possible. Sporadic power outages could occur throughout the affected area.
Transport
The winter weather will likely cause ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of highways if driving conditions become too hazardous. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.
Advice
Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. If routing shipments by truck through the affected area, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
