The snow squall guide: Preparation and caution on winter roadsWhat are snow squalls?

Snow squalls are brief but intense winter weather events often linked to strong cold fronts. They can cause sudden white-out conditions and icy roads within minutes, even if there’s no major winter storm happening. While they usually last less than an hour and might only result in minor snow accumulation, they pose significant risks to drivers due to reduced visibility, gusty winds, and rapidly falling temperatures. These conditions have historically led to deadly traffic accidents.

What is the difference between a snow squall and a snowstorm?

The difference between a snow squall and a snowstorm is the duration of the event. Snow squalls are usually very short-lived (on the order of 30-60 minutes) and extremely intense. A snowstorm could last for several hours or even days.

Actions to take

In response to a snow squall warning, individuals should follow the guidelines provided by the weather service, which encompass the following key actions:

Avoid or delay travel: If a snow Squall warning is issued for your area, avoid or delay motor travel until the squall passes through your location. There truly is no safe place on the highway during a snow squall.

Reduce speed and increase visibility: If you find yourself already on the road during a snow squall, prioritize safety by reducing your speed. Turn on both your headlights and hazard lights to enhance visibility for yourself and other drivers.
