What to do
Go indoors at the first sound of thunder. Avoid open shelters and stay away from plumbing and corded equipment indoors during the storm. Wait at least 30 minutes after the last thunder before resuming outdoor activities.
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.
