During extreme winter events, standard response plans may no longer be valid. These events can have significant consequences for society. In many countries, there are roads in areas with extreme conditions such as mountain passes requiring convoys, roads in open areas exposed to snow drift and roads vulnerable to avalanches. However, extreme weather conditions can also happen anywhere; examples include heavy snowfall, freezing rain, extreme cold, fast changing weather conditions, fast increasing temperature and melting snow, which can cause landslides, or flooding. Heavy snowfall events might shut down traffic if winter services reacts not adequate. Methods and practices on how to handle heavy snowfalls are shown in this session.
