The storm stretched as far west as New Mexico and intensified as heavy snow, freezing rain, and dangerously cold temperatures moved into the eastern two-thirds of the nation. By late Sunday morning (10:47 am EST), outage tracking site PowerOutage.us reported more than 850,000 homes and businesses without power, including nearly 290,000 in Tennessee and more than 100,000 each in Mississippi, Texas, and Louisiana. Kentucky, Georgia, Virginia, and Alabama were also heavily affected.
Air travel faced severe disruption. According to FlightAware, more than 10,200 US flights scheduled for Sunday were canceled, following over 4,000 cancellations on Saturday. Washington, DC’s Ronald Reagan National Airport confirmed that all flights there were canceled for the day.
Major airlines scrambled to respond. Delta Air Lines said it planned to operate a reduced schedule depending on real-time weather conditions, including frozen precipitation and worsening storms later in the day. The carrier had already adjusted flights on Saturday, canceling additional routes in Atlanta, Boston, and New York City, while relocating cold-weather specialists to help with de-icing and ground operations at southern airports.
The National Weather Service warned that heavy snow would continue from the Ohio Valley to the Northeast, with parts of New England expecting up to 18 inches. Meanwhile, much of the Southeast and sections of the Mid-Atlantic were forecast to see rain and freezing rain. Behind the storm, forecasters predicted bitterly cold temperatures and dangerous wind chills from the southern plains through the Northeast, increasing the risk of prolonged travel hazards and infrastructure strain.
Federal and State Emergencies Declared
Calling the storm system “historic,” President Donald Trump approved federal emergency disaster declarations for multiple states, including South Carolina, Virginia, Tennessee, Georgia, North Carolina, Maryland, Arkansas, Kentucky, Louisiana, Mississippi, Indiana, and West Virginia.
In a social media post, Trump said authorities would continue coordinating with states in the storm’s path and urged residents to “stay safe” and “stay warm.”
According to the Department of Homeland Security (DHS), 17 states and the District of Columbia declared weather-related emergencies. DHS Secretary Kristi Noem warned Americans to prepare for extreme cold conditions.
“It’s going to be very, very cold,” Noem said at a Saturday news conference. “We encourage everyone to stock up on fuel and food. We will get through this together.”
Power Grid Under Pressure
Federal energy officials took emergency steps to stabilize the power grid. The Department of Energy (DOE) authorized the Electric Reliability Council of Texas (ERCOT) to use backup power generation at major facilities, including data centers, to help prevent blackouts.
A similar emergency order was later issued for PJM Interconnection, the grid operator serving parts of the Mid-Atlantic, allowing it to run certain power resources regardless of normal environmental or regulatory limits.
Grid operators nationwide increased precautions to avoid rolling blackouts as demand for heating surged. Dominion Energy, whose Virginia service area includes the world’s largest concentration of data centers, warned that if ice forecasts held true, the storm could become one of the most significant winter events in the company’s history.
