It's a fact of Winter that the weather is cold. Add to that Arctic cold during or immediately following a snowstorm and you have a recipe for "life-threatening" conditions. Cold weather and wind combine during the Winter months to "rob our bodies of heat and moisture". This condition we call wind chill which is an attempt to estimate the effects of wind and cold temperatures on the human body. The heat loss that occurs is more pronounced when the wind is faster or the temperature is lower. The longer you are exposed to conditions of extreme cold, the more likely you will fatigue and put yourself in danger of losing your life. It is important to monitor the conditions at hand during a Winter storm, but even more important to know well ahead of time what to expect once the storm has passed. It is then that the extremely cold weather usually sets into a region! If you become stuck in a Winter storm because the weather is adverse, then you need to know that the weather following it may be just as dangerous
