Some reminders about winter weather preparedness:

  • Stay indoors if possible.
  • If you must go outside, dress appropriately:
    • Multiple layers of loose fitting clothing to promote insulation.
    • Heavy woven materials are ideal.
    • Wear a hat – 50% of your body heat escapes through you head.
    • Wear a scarf or something to cover your mouth and nose.
    • Cover as much of your skin as possible.
    • Mittens are better than gloves.
  • Remember, rarely is a trip a “MUST” trip.  Plan accordingly to avoid hazardous winter travel.
  • If travelling is absolutely unavoidable, please prepare a winter safety kit for your car. Details regarding what should be included in this kit can be found in this document.  Never leave your vehicle when stranded. It is your only sure source of protection from the elements.
