“Oftentimes the strong winds and cold temperatures associated with blizzards can produce dangerous wind chills, which can lead to hypothermia and frostbite, especially if stuck outside for extended periods,” he said.

Your first line of defense

Awareness and avoidance are your best weapons against blizzards and other bad winter weather.

If you’re taking a road trip, “begin checking weather conditions about a week in advance of your trip and make sure to check again each day as the weather forecasts become more fine-tuned,” Muccilli said …
