What to do
Get inside a substantial building or enclosed hard-topped vehicle when thunder is heard. Check warnings for damaging winds, hail, tornadoes, or flash floods. Postpone activities where you cannot reach shelter quickly.
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.
