What to do
Dress in layers and keep clothing dry. Arrange a warm backup location and check on neighbors. Use only equipment intended for indoor heating, and follow its instructions.
Before the next alert
Save local emergency management contacts and share your plan with everyone in the household. Check what supplies, accessible transportation, and pet arrangements you would need if you had to leave.
