Fast Snow Squalls May Rapidly Disrupt I-95 Travel in Mid-Atlantic
In the Mid-Atlantic region, snow squalls pose serious risks for drivers, especially on I-95 and other major highways. These weather events are characterized by brief yet intense bursts of snowfall that can rapidly deteriorate road conditions.
What Are Snow Squalls?
Snow squalls are defined as narrow bands of heavy snow that often occur alongside gusty winds. According to the National Weather Service, visibility can plummet to nearly zero in a matter of minutes. Most of these snow events last between 15 to 60 minutes but can make travel extremely hazardous.
How Do Snow Squalls Form?
- Snow squalls typically develop along strong winter cold fronts that move southeast from the Ohio Valley.
- As cold air moves in behind these fronts, it can cause sudden bursts of heavy snow and strong winds.
- The rapid drop in temperature can freeze previously wet roads, turning them icy and treacherous.
Driving Hazards Associated with Snow Squalls
The greatest danger during a snow squall is the abrupt change in driving conditions. Drivers may encounter clear skies or light snow and then suddenly find themselves in a whiteout scenario. This has led to multiple vehicle accidents on significant routes like I-95, I-81, I-83, I-66, and I-270, especially during peak commuting hours.
Snow Squall Warnings
The National Weather Service issues Snow Squall Warnings when these hazardous conditions arise. These alerts advise drivers to:
- Slow down immediately
- Turn on headlights
- Increase following distance
- Avoid sudden braking
Regions Most Affected
Snow squalls are frequently seen in interior parts of Pennsylvania, Maryland, Virginia, West Virginia, and northern Delaware. However, urban areas and coastal highways can also experience these dangerous conditions during significant cold fronts.
For commuters and early workers in the Mid-Atlantic, the impact of snow squalls can be significant, emphasizing the need for caution during winter weather events.
