Massive winter storm grips much of the U.S., driving outages, dangerous travel and widespread cancellations

A massive winter storm sweeping across the United States is delivering a volatile mix of heavy snow, sleet, and freezing rain—conditions that can quickly shift from manageable to dangerous, especially where ice accretes on roads and power lines. Forecasters said impacts would continue through Monday, with the most serious ice threat focused from the Lower Mississippi Valley into parts of the Southeast, while wintry precipitation and accumulating snow extend into the Ohio Valley and parts of the Northeast.

Utilities reported widespread outages as the storm moved across multiple regions. In some states, the number of customers without power climbed into the tens of thousands, and in several places—particularly across portions of the South—ice and falling limbs were expected to make repairs difficult until precipitation tapered and crews could safely access damaged areas. Officials repeatedly urged drivers to stay off roads where freezing rain can turn pavement into a sheet of black ice, and where crashes can block plows and emergency responders.

Air travel disruptions were extensive. Airlines canceled thousands of flights and reported many more delays as aircraft de-icing, crew availability, and airport ground operations slowed. The cascading impact of a multi-day storm often spreads beyond the areas receiving the heaviest precipitation because planes and crews are positioned across the national network; when a hub or key corridor is disrupted, knock-on delays can propagate to routes far from the storm’s core.

Federal and state responses ramped up as conditions worsened. Emergency declarations were approved in multiple states, and federal agencies positioned resources to help with response and recovery. As the storm advances, officials emphasized that the biggest hazards can vary by region—ranging from heavy snow that reduces visibility and blocks roads, to ice that brings down power lines, to bitter cold that increases the risk of hypothermia for anyone stranded without heat.

For residents, the practical guidance remained consistent: monitor local alerts, avoid unnecessary travel, charge devices, stock essential supplies, and have a plan for heat and shelter if power fails. The storm’s broad footprint also raised concerns for vulnerable populations, including older adults and people without stable housing, as cold exposure can become life-threatening quickly—especially overnight or when wind intensifies.

• Check local winter storm and ice warnings before driving; conditions can vary block by block.
• If you must travel, keep blankets, water, and a phone charger in the vehicle in case of delays or closures.
• Avoid downed wires and report outages; assume any fallen line is energized.
