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. It is defined very differently in Miami, FL, than in Fairbanks, AK. 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, 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. If you, or someone you know, have been a victim of a winter storm, please share your story so we can prevent others from becoming a victim. When you write, please note that NWS has permission to use your story and, if possible, let us know the town and state you were in and the year the event took place.
