Twin Cities blizzard cancels 700+ MSP flights, grounds travel
A powerful March winter storm produced heavy, wet snow with bands dropping 2–3 inches per hour, prompting NWS winter‑storm and blizzard warnings, MnDOT no‑travel advisories, widespread closures and Gov. Tim Walz to authorize the National Guard to assist local governments. Airlines issued waivers and proactively canceled hundreds of flights at MSP — MSP’s tracker showed 333 canceled arrivals and 360 canceled departures (about 693 cancellations) as of roughly 8:10 a.m. Sunday — and travelers were warned to check with carriers as travel was expected to be very difficult or impossible.
📌 Key Facts
- Meteorologists describe the system as an amplified spring storm (an upper‑level energy packet tracking from Russia into the Upper Midwest with a surface low moving from eastern Colorado into Iowa/Wisconsin) pulling Gulf moisture north; forecasters say it could be the season's biggest snow and note a narrow, high‑end band can produce double‑digit totals, with the highest odds for 18+ inches in southeast Minnesota and southwest Wisconsin but pockets of heavy snow possible in the greater Twin Cities.
- The National Weather Service has issued winter storm warnings for the Twin Cities metro for Saturday evening into early Monday (product windows reported from late Saturday through early Monday), with blizzard warnings in much of southwestern and south‑central Minnesota; NWS warns travel could become 'very difficult or impossible' late Saturday night into Sunday.
- Intense snowfall rates of 2–3 inches per hour are possible in the heaviest bands, producing heavy wet snow (some locations could top a foot), blowing snow and white‑out conditions; increasing winds may keep blizzard conditions into Sunday night and create lingering hazardous travel into Monday.
- Minnesota transportation and safety actions include MnDOT advising no travel on highways and I‑90 in south‑central Minnesota starting 7 a.m. Sunday and no‑travel advisories across swaths of southeast and southwest Minnesota; many businesses, churches and some clinics/zoo/markets announced Sunday closures or virtual services.
- Minneapolis–St. Paul International Airport experienced mass disruptions: MSP's tracker showed about 333 canceled arrivals and 360 canceled departures (~700+ canceled flights) by roughly 8:10 a.m. Sunday; the airport had warned earlier that airlines were proactively canceling flights and, as of about 6 a.m., reported more than 450 cancellations for Sunday.
- Major carriers have issued weather waivers: Delta, Sun Country, American and United announced waivers for affected flights; Sun Country specifically allowed one‑time free rebooking for certain tickets to/from Minneapolis and several Wisconsin cities for travel scheduled Sunday if purchased before March 12.
- State emergency response: Governor Tim Walz signed an emergency executive order authorizing the Minnesota National Guard to support local governments during the storm, citing inadequate local/county resources; Steele County has already requested Guard assistance.
- Early Sunday observations and totals showed heavy band development and measurable accumulations across the metro and southern suburbs (examples: Elko New Market 8", Apple Valley 7.5", MSP 5", Chanhassen 5", Prior Lake 5", St. Paul 3.4"), with heavy bands expanding into western Wisconsin and snow expected to taper northwest to southeast Sunday afternoon/evening.
