Boston, MA – Massachusetts 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 awareness efforts continue Wednesday, Oct. 28, residents are being reminded that even brief bursts of heavy snow can turn routine travel into a serious safety threat.
According to the National Weather Service NWS , snow squalls are brief but intense periods 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 Massachusetts Highways Unlike prolonged winter storms, snow squalls can arrive suddenly, creating near whiteout conditions and rapidly covering roadways.
Interstate 90, Interstate 93, Interstate 95, Interstate 91 and Interstate 495 are among the major travel corridors where sudden snowfall could create hazardous driving conditions.
Motorists traveling through Worcester, Middlesex, Essex, Hampden and Berkshire counties may face additional risks on exposed highways, elevated roadways and rural routes.
Western and central Massachusetts can be especially vulnerable to sudden snow bursts during colder months, particularly across higher elevations in the Berkshires and Worcester Hills.
What Is a Snow Squall Warning? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or expected to develop shortly.
These warnings typically 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 Massachusetts 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 severe conditions when possible. Never stop in an active travel lane during a whiteout. Residents can monitor forecasts and official warnings through the NWS Boston/Norton office and the NWS Albany office , which serves Berkshire County.
Winter weather awareness efforts continue through Saturday, Oct. 31, emphasizing how quickly snow squalls can transform Massachusetts highways into dangerous whiteout conditions.
