Avoid unnecessary travel. Move animals to sheltered areas. Have a water supply available. Most animal deaths in winter storms are from dehydration. Stay indoors during the storm.
Winter storms can last for several days.
Suppliers of propane and fuel oil may not be able to replenish depleted supplies during severe weather. Electric and gas services may be temporarily disrupted when many people demand large amounts at the same time. Lower the thermostat to 65 F during the day and 55 F at night. Close off unused rooms, and stuff towels or rags in cracks under doors. Cover windows at night.
