Vulnerability and Impacts <br />Life Safety and Health: Winter weather poses a significant threat to health and life safety, and the entire <br />population in Kittitas County is vulnerable to winter weather events. A large number of deaths that occur <br />due to winter weather is not directly related to the weather itself. For example, people die in traffic <br />accidents due to ice on the roads, heart attacks while shoveling snow, and hypothermia from prolonged <br />exposure to cold. Injuries related to ice and snow occur in automobiles (70%), people that are caught out <br />in the storm (25%), and the majority are males over 40 years old.265F <br />266 Additionally, winter weather can <br />create slippery and icy conditions increasing the risk of slips, falls, resulting in fractures and head trauma. <br />Hazardous driving conditions caused by snowfall and icy roads increase the risk of vehicle accidents, <br />which can lead to injuries and fatalities. Heavy ice and snow accumulation can weigh down trees, and <br />communication and power lines which can result in extensive power outages. Subsequently, power <br />outages lead to a loss of heat in residences and places of business.266F <br />267 If heat is not available for an <br />extended period of time during a winter weather event, individuals can expose themselves to extremely <br />cold temperatures even when indoors. <br /> <br />Hypothermia and frostbite are both dangerous conditions that can happen when a person is exposed to <br />extremely cold temperatures. Hypothermia is when the body begins to lose heat faster than it is produced <br />which leads to lower body temperatures. Those at a higher risk for hypothermia include, but are not <br />limited to, older adults with inadequate food, clothing, or heating, babies sleeping in cold bedrooms, and <br /> <br />266 NOAA, National Severe Storms Laboratory.
