US: Adverse winter weather forecast across central and south-central regions through at least early Nov. 9

Adverse winter weather is forecast across parts of the central and south-central US through at least early Nov. 9. Several rounds of moderate-to-heavy snowfall are expected over parts of the central and southern Rockies and adjacent High Plains over the coming days. Snowfall accumulations of over 60 cm (24 inches) are expected across higher elevations through early Nov. 9, with widespread accumulations of over 15 cm (6 inches) likely in lower elevations. Hazardous travel conditions are likely due to reduced visibility caused by blowing snow.

As of early Nov. 6, the National Weather Service (NWS) has issued winter storm warnings across parts of central, northern, and western New Mexico and central, eastern, and southern Colorado. Winter storm watches are in place for parts of southern New Mexico, the far northwestern Texas Panhandle, the far western Oklahoma Panhandle, and southeastern Colorado. Winter weather advisories are in place across much of the rest of the affected area. Officials could update and extend the coverage of the weather alerts over the coming days.

Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.

The winter weather will likely cause ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities will probably 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.
