Get inside the nearest sturdy building immediately, away from windows
Go to the lowest floor and an interior room or hallwaya bathroom, closet, or stairwell is ideal

Abandon your car if no sturdy building is reachable — lie flat in a low ditch or depression and cover your head if no shelter availableonly if truly no building or shelter is within reach
Avoid large open-span buildings like big-box stores, gyms, or auditoriumsthe roof structure is more likely to fail
Cover your head and neck with your arms, a coat, or a blanket wherever you shelter
Keep kids or others with you close and calmphysically stay together in the shelter spot

Get out of your car and move to higher ground immediately if water is rising around the vehicle
Avoid walking through moving wateras little as 6 inches can knock an adult off their feet
Stay off low bridges, dips, and underpasses until the warning ends
Head for higher floors if you're in a building in a flood-prone area — don't go to the basement

While You Wait It Out

Keep a battery or crank weather radio, or your phone with alerts onso you know when the warning is cancelled or extended
Stay put until the warning expires or local officials give an all-cleardon't leave shelter just because the sky looks calmer
Text rather than call people to let them know you're safetexts get through more reliably when networks are jammed
Check your phone's battery and consider a backup power bank in your bag or carfor exactly this kind of situation
Watch for downed power lines, broken glass, or debris before you move your car or walk back outside
Report a downed power line to the utility company and keep everyone away from ittreat every line as live

Before You Get Back on the Road

Check current road conditions and closures before drivinga route that was fine 20 minutes ago may now be flooded or blocked
Watch for a second wave of stormsmany severe weather events come in a line or cluster, not a single cell
Recheck the warning status for your route's whole path, not just where you are now if driving through multiple counties or towns
