What's the difference between a winter storm watch and a warning?
Heavy snowfall and extreme cold can immobilize an entire region. Even areas that normally experience mild winters can be hit with a major snowstorm or extreme cold. Winter storms can result in flooding, storm surge, closed highways, blocked roads, downed power lines and hypothermia.
General information on extreme cold hazards and winter storms is available at the following web pages:
- FEMA's Winter Storms and Extreme Cold web page
- FEMA's Winter Storm Preparedness Tips
- The Centers for Disease Control and Prevention's (CDC) Winter Weather web page
- The Department of Health and Human Services' (HHS) Extreme Cold and Winter Storm web page
