Blizzards and DHS Shutdown Continue to Snarl U.S. Air Travel With Thousands of Cancellations
A sprawling, erratic storm system — producing blizzard‑force snow in the Upper Midwest, high winds and tornado threats in the mid‑Atlantic, large wildfires in Nebraska, heavy rain in Hawaii and an early Western heat wave — has snarled U.S. air travel, triggering thousands of cancellations and delays (more than 4,800 cancellations and 12,800 delays reported Monday and 1,000+ cancellations with ~4,200 delays Tuesday), with major disruption at Minneapolis–Saint Paul, Chicago O’Hare, Atlanta and New York area airports. Compounding the chaos, a partial Department of Homeland Security shutdown that began Feb. 14 has left TSA employees working without pay, prompting over 300 resignations, sharply higher call‑out rates and missed paychecks, and officials warn of increasingly long security lines and further travel disruptions.
📌 Key Facts
- A broad, erratic storm system produced blizzard conditions and heavy snow across the Midwest and Great Lakes — about 11.5 million people were under blizzard warnings and 4.3 million under winter-storm warnings — with some locations receiving more than a foot to over 2 feet of snow.
- Air travel was severely disrupted: Sunday saw 600+ cancellations at Minneapolis–Saint Paul and about 850 at Chicago’s airports (plus additional cancellations through Detroit); by Monday more than 4,800 flights were canceled and delays topped 12,800 nationwide; on Tuesday there were more than 1,000 cancellations and roughly 4,200 delays, with Atlanta among the worst‑affected hubs.
- An ongoing partial Department of Homeland Security shutdown (begun Feb. 14) has left TSA employees working without pay and contributed to staffing shortages — more than 300 TSA staffers have quit, call‑out rates have more than doubled, and some officers are skipping shifts or taking second jobs, compounding weather‑driven travel disruptions.
- TSA unions warned travelers to expect increasingly long security lines; passengers described arriving hours early or sleeping in airports as agents missed paychecks and called out, and union officials held news conferences urging preparedness.
- The storm was part of a nationwide cluster of extremes: AccuWeather estimated more than 200 million people faced some form of dangerous weather (heat, wildfire, floods, freeze), and an early‑season heat wave baked the West — Phoenix was forecast for multiple consecutive 100°F days and Southern California saw near‑record highs.
- Severe wildfires in Nebraska burned vast areas — three large grassland fires burned more than 1,140 square miles in total, including the Morrill County fire that alone exceeded 700 square miles — prompting National Guard deployments.
- A separate Pacific storm caused severe flooding in Hawaii, with parts of Maui receiving more than 20–23 inches of rain, tens of thousands of customers without power, widespread road closures, landslides, rescues, shelter openings and infrastructure damage.
- High winds and the storm complex left large power outages (Poweroutage.com data showed more than 500,000 homes and businesses without power early Tuesday in multiple states) and contributed to deadly impacts, including a New York City apartment fire that killed four people, including a child.
