A snowstorm is a very heavy snowfall, sometimes accompanied by strong winds that can create blizzard-like conditions and severe wind chill.
Snowstorms can make driving dangerous. On mountains, snowstorms can increase the risk of avalanches, which can fall onto roads and ski fields.
In very large quantities, snow can isolate communities, cut communications, disrupt power supply, and cause buildings to collapse under its weight.
Prolonged low temperatures present a risk to people and livestock, especially if deep snow stays on the ground for extended periods, preventing livestock from grazing.
