Cold Weather Safety Tips

Wear multiple layers. Use several layers of loose-fitting, lightweight clothing to trap body heat.

Protect your extremities. Wear a hat, face mask, and gloves to prevent heat loss and protect skin.

Stay dry. Wet clothing loses its insulation value and can lead to faster heat loss.

Limit outdoor time. If you must go outside, keep your trips short to minimize the risk of frostbite.

Check on others. Ensure elderly neighbors and pets have adequate warmth and shelter.

Know the signs. Watch for symptoms of frostbite, such as pale or numb skin, and hypothermia, which includes confusion and shivering.

The hazardous weather outlook remains in effect for northwest and western Pennsylvania through the weekend.
