Texas & Regulations
Is it safe to shelter in a shed during a lightning storm?
No. The National Weather Service lists small sheds among the structures that do not protect you from lightning. Its safe options are a substantial, fully enclosed building with electrical wiring and plumbing, or a hard-topped metal vehicle with the windows up.
A storage shed is fine for keeping gear dry, but it is not a place to wait out a thunderstorm. If you hear thunder, head for the house or a vehicle, and stay there until at least 30 minutes after the last thunder you hear.
Why it matters
Texas gets plenty of thunderstorms, and NWS records show Texas has had the second-highest total of lightning deaths of any state (226 from 1959 to 2017, behind Florida). Adjusted for population, Texas ranks much lower, but the habit of ducking into the nearest shed while mowing, fencing or working on a ranch is a real risk.
The reason is simple: a shed with no plumbing or wiring gives lightning no safe path to the ground, and the walls do little to protect you. NWS also advises that even inside a safe building you should stay away from corded electronics, plumbing, windows and doors during a storm. If you wire a workshop, plan for surge protection on the electrical service, and ask your local electrical inspector what applies where you live.
Real examples
Mowing at the back of the property
A storm builds while you are far from the house. Walk or drive to the house or a closed vehicle at the first thunder rather than stepping into the equipment shed.
Working on a ranch or lot
A hard-topped truck or car with the windows rolled up is a better refuge than a loafing shed, barn lean-to or carport.
A wired workshop or studio
A fully enclosed, finished building with electrical wiring and plumbing fits the NWS idea of a substantial building, but you should still avoid touching plumbing and corded devices during the storm.
Common mistakes
- Assuming a metal or grounded shed is safeNWS guidance lists sheds among unsafe shelters, and a metal skin does not change that. Do not count on the building to protect you.
- Going back out too soonNWS advises waiting at least 30 minutes after the last thunder you hear before leaving a safe shelter.
- Using the shed doorway as a lookoutStanding in an open door or near the walls of a small building keeps you exposed. Get to proper shelter early instead of watching the storm.
