Winter storms can range from a few hours of moderate snow to blizzard conditions lasting several days. They vary in severity and geographic scope, but all winter storms bring dangerous low temperatures and potentially strong winds, icing, sleet or freezing rain. It is important to prepare your home, vehicle and supplies in case a winter storm leaves you stranded or without power or heat for an extended period. Preparations include winterizing your home and vehicle, having emergency supplies like food, water and warm clothing, and knowing how to stay safe, such as avoiding carbon monoxide poisoning from alternate heating sources.
