The National Weather Service (NWS) has issued winter storm warnings and winter weather advisories across multiple U.S. regions, with forecasts of up to 18 inches of snow in some areas.

Why It Matters

NWS winter weather advisories signal that hazardous but manageable conditions are occurring, imminent, or likely, so people should use caution. Meanwhile, winter storm warnings mean dangerous weather is imminent or occurring, and immediate action is needed to protect life and property.

The warnings coincide with one of the busiest travel seasons of the year, raising concerns about hazardous driving conditions and significant disruption.

The NWS has cautioned that poor visibility, icy roads, and strong winds may create dangerous conditions and exacerbate the risk of accidents and delays.

What People Are Saying

For those under a winter weather warning, the NWS says: "If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.

"The latest road conditions for the state you are calling from can be obtained by calling 5 1 1. Persons should consider delaying all travel. Motorists should use extreme caution if travel is absolutely necessary."

For winter weather advisories, the NWS says, "slow down and use caution while traveling", adding: "Be prepared for slippery roads. If you are going outside, watch your first few steps taken on stairs, sidewalks, and driveways. These surfaces could be icy and slippery, increasing your risk of a fall and injury."

What Happens Next

The NWS urges residents to stay alert to rapidly changing weather and road conditions, especially in high-elevation, rural, and mountainous regions where snow accumulation may be greatest.

For those who must travel, the service recommends telling someone your itinerary and carrying an emergency kit that includes a battery powered radio, booster cables, shovels, non-perishable food, water, blankets, and other survival essentials.

The NWS has also advised the public to check their official website and local media sources for the latest advisories and warnings as conditions evolve.
