Ways to prepare and stay safe now

  • During
    Stay indoors during the storm.
    Prolonged exposure to cold can cause hypothermia.
    Walk and drive carefully on icy sidewalks and roads.
    Many injuries and accidents are caused by slippery conditions.
    Before driving, let someone know your destination, route, and expected time of arrival.
    If your car gets stuck, it’ll be easier to find you.
    If you lose feeling and color in your nose, ears, hands, or feet, cover the exposed area, avoid rubbing your skin, and seek medical help immediately.
    You may have frostbite.
    When shoveling snow, take breaks and lift lighter loads.
    Working too hard can lead to heart attacks.
    Stay dry.
    Wet clothes make you lose body heat, increasing your risk of hypothermia.
