St. Paul, MN – Minnesota drivers can encounter dangerous highway conditions when fast moving snow squalls suddenly reduce visibility to near zero, creating slippery pavement and increasing the risk of multivehicle crashes. As winter weather preparedness messaging continues Wednesday, Oct. 28, residents are being reminded that brief bursts of heavy snow can turn routine travel into a serious safety threat.
According to the National Weather Service NWS , snow squalls are short lived, intense bursts of snowfall accompanied by gusty winds and rapidly deteriorating visibility. These conditions can develop within minutes, leaving motorists little time to respond.
How Snow Squalls Threaten Minnesota Highways Unlike prolonged winter storms, snow squalls can arrive suddenly, creating near whiteout conditions and quickly covering roadways.
Interstate 94, Interstate 35, Interstate 90, Interstate 494 and Interstate 694 are among Minnesota's major travel corridors where sudden snowfall could create hazardous driving conditions.
Motorists traveling through Hennepin, Ramsey, Dakota, Olmsted, Stearns and St. Louis counties may face additional risks on exposed highways, bridges and heavily traveled commuter routes.
Western and southern Minnesota are particularly vulnerable to blowing snow across open farmland, while northeastern communities near Lake Superior can experience localized lake effect snowfall during favorable winter weather patterns.
What Is a Snow Squall Warning? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
These warnings generally last 30 to 60 minutes and may activate Wireless Emergency Alerts on compatible mobile phones.
A warning signals an immediate threat to motorists, particularly those traveling at highway speeds where sudden visibility loss can contribute to chain reaction crashes.
What Minnesota Drivers Should Do When a Snow Squall Warning is issued, the safest option is to delay travel until conditions improve .
Motorists already traveling should:
Reduce speed gradually and increase following distance. Turn on headlights to improve visibility. Avoid sudden braking or abrupt lane changes. Exit the highway safely before entering dangerous conditions when possible. Never stop in an active travel lane during a whiteout. Residents can monitor forecasts and official warnings through the NWS Twin Cities office , NWS Duluth office , NWS Grand Forks office and NWS La Crosse office , which serve different portions of Minnesota.
Winter weather preparedness messaging continues through Saturday, Oct. 31, as part of this editorial series , emphasizing how quickly snow squalls can transform Minnesota highways into dangerous whiteout conditions
