Winter storms, snow, windchill, frost, ice and extreme cold are a coast-to-coast threat to the United States and its territories. Even Hawaii gets snow on its Big Island and frost is a major threat to crops in Southern states. Major cities as far south as Atlanta and Dallas have been paralyzed by snow and ice. Extreme cold is a relative term. In Miami it is defined very differently than in Fairbanks. This page is designed to teach you how to stay safe in a winter storm or in abnormally cold weather for your area. If you know what to do before, during, and after a winter event, you can increase your chances of survival. On this site, you will find information on winter alerts, science and hazards, as well as snow coverage maps, and information describing the different types of winter storms as well as how to deal with extreme cold. You'll also find a broad array of educational materials.
