Arctic Cold Blast Plunges US Temperatures

In-Depth Analysis

The polar vortex, a large area of low pressure and cold air surrounding Earth’s poles, is expanding and pushing cold air south. This phenomenon is common during winter but this year it is particularly intense, with three waves of Arctic air expected.

**How to Prepare:** - Winterize homes and water lines. - Have furnaces checked and heating oil/propane ordered. - Prepare for potential power outages with generators (used safely outdoors), battery-powered lanterns, and extra blankets. - When going outside, cover as much skin as possible to prevent frostbite. Wear layers of loose-fitting, warm clothing, hats, and mittens.

**Who This Affects Most:** - Residents of the Midwest and Northeast are most directly impacted by the plunging temperatures. - Vulnerable populations, such as the elderly and those without adequate heating, are at higher risk.
