Dover, DE – Imagine heading north on Interstate 95 toward Wilmington for Thanksgiving when a sudden wall of blowing snow sweeps across the highway. Within seconds, vehicles ahead become difficult to see, brake lights fade into the whiteout and a familiar holiday drive turns dangerous. It's the kind of fast moving winter weather Delaware motorists should recognize as Thanksgiving approaches Thursday, Nov. 26.
According to the National Weather Service NWS , these intense bursts of snowfall, officially known as snow squalls and sometimes described as "micro blizzards," can produce gusty winds, near zero visibility and rapidly deteriorating road conditions.
Unlike prolonged winter storms, snow squalls can develop quickly, leaving drivers little time to react.
Delaware Highways Where Sudden Whiteouts Are a Concern Interstate 95 through Wilmington and Newark is a major Thanksgiving travel corridor where sudden winter weather can create hazardous driving conditions.
Delaware Route 1, connecting northern Delaware with Dover and the beaches, and U.S. Route 13 through New Castle, Kent and Sussex counties also face winter driving risks.
U.S. Route 301 near Middletown and Interstate 495 around Wilmington are additional routes where heavy snow and reduced visibility could affect motorists.
Although significant snowfall is less frequent in southern Delaware than in some neighboring inland regions, sudden snow showers and gusty winds can still create hazardous conditions when temperatures support snow accumulation.
What Happens When a Snow Squall Warning Is Issued? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
Warnings typically last 30 to 60 minutes and may trigger Wireless Emergency Alerts on compatible mobile phones.
Sudden whiteouts at highway speeds can increase the risk of multivehicle crashes, particularly when drivers brake abruptly or follow too closely.
What Thanksgiving Travelers Should Do If a Snow Squall Warning is issued, the safest option is to delay travel until conditions improve .
Drivers already traveling should gradually reduce speed, increase following distance, activate low beam headlights and avoid sudden braking.
If visibility deteriorates, safely exit the highway when possible rather than stopping in an active travel lane.
Before departing, motorists should check DelDOT for highway conditions and NWS Mount Holly for official forecasts and warnings covering Delaware.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike Delaware during the holiday. Recognizing how quickly dangerous winter conditions can develop could help motorists make safer travel decisions as Thanksgiving approaches.
