The National Weather Service has issued a Wind Chill Advisory from midnight Saturday January 4 through 6:00pm Sunday January 6.  The advisory transitions to a Wind Chill Warning from 6:00pm Sunday through noon on Tuesday January 7.  Temperatures are not expected to rise about zero (0) between Sunday morning and Tuesday afternoon.  Wind chills may reach as low as -50°!!  These are life threatening temperatures.


What may be a minor inconvenience under normal temperatures can rapidly accelerate into a dangerous situation under these temperatures.  Under normal winter conditions, a ten minute walk from a car in the ditch would be inconvenient.  That same walk under the predicted extreme conditions may cause frostbite and hypothermia. 


Signs and symptoms of frostbite include the loss of feeling and color in parts of the body. For hypothermia signs and symptoms include Signs and symptoms include uncontrollable shivering, feelings of numbness, drowsiness, exhaustion, confusion, memory lapses, slow or slurred speech, slow breathing and pulse rates, failing eyesight, poor coordination and possible unconsciousness. If you are experiencing these symptoms, you should seek immediate emergency medical assistance.


If persons must be outside:

  • Ensure that someone inside knows your schedule and location.  Follow up with that person when you arrive at your destination.
  • Identify who you will contact in case of an emergency and make sure they are available to (send) help.  Your reaction time to request assistance is critical at these temperatures.
  • Have tow truck numbers programmed into your cell phone so you don’t waste valuable time trying to find a towing company to call.


Cold Weather Precautions:

  • Monitor your food intake and physical output and maintain a regular diet to help your body better handle the severe weather conditions.
  • Hydrate - Drinks with caffeine, sugar and alcohol take longer for your body to absorb and do not hydrate as well. Water is usually the best choice.
  • People should be aware of the amount and intensity of their physical activity, both indoors and out. Avoid overexertion. Cold weather puts additional strain on the body, especially the heart.
  • If you have to go outside, wear appropriate clothing that will adequately insulate you from the cold and provide protection from the wind.
  • Older adults, those in fragile health and smaller children can be more readily affected by the cold than the average adult.
  • Check on loved ones and neighbors, especially those in fragile health, preferably by telephone.  Pay particular attention to older neighbors who may be outdoors attempting to shovel snow or engaged in some other activity.
  • Never leave children or pets alone in vehicles. Temperatures in vehicles can drop rapidly.
  • Pets can be greatly affected by the cold and should not be exposed longer than they have to be.
  • Large animals need to be kept out of the wind and have a dry place to lie down. Water supplies should be checked to avoid freezing and diets should be adjusted to increase energy content by 5%.
  • Check heating units. Poorly operating or damaged heating units can release carbon monoxide gas. Test carbon monoxide detectors for proper operation and battery life.


Carbon monoxideis an odorless, colorless, tasteless gas that kills more than 500 Americans every year. Never use generators, grills, camp stoves, or other gasoline or charcoal-burning devices inside your home, basement, and garage or near a window. Also, make sure you have installed a carbon monoxide detector in your home to alert you and your family to this "silent killer."
