The <a href="https://247newslive.com/tag/national-weather-service/”>National Weather Service issued winter weather warnings early this week for several states. Some areas of the Western United States are bracing themselves for heavy snowfall. We’ll break these systems down into their key features and possible impacts.
What it means: Winter weather impacts
Winter weather can be very challenging. Temperatures below freezing can pose a serious threat to vulnerable groups, such as infants, elderly people, or those who are homeless. Hypothermia can result from these conditions. Winter storms may also disrupt your daily routine by causing power failures due to accumulation of heavy snow and ice on the power lines. The hazardous road conditions caused by snow and ice may also increase accidents and cause travel delays.
