As winter approaches, understanding cold weather alerts from the National Weather Service is crucial for staying safe and informed. These alerts are designed to notify the public about impending hazardous cold conditions, allowing individuals and communities to take necessary precautions. One of the key factors considered in cold weather alerts is wind chill. Wind chill is a measure of how cold the air feels on your skin when combined with the wind. It can make the air feel significantly colder than the actual temperature, leading to a higher risk of hypothermia and frostbite.
