Thunderstorm FAQs
Find answers to the most common questions about thunderstorm safety, finding shelter, protecting your electronics, and how close lightning needs to be before it's a real danger — because a little know-how goes a long way when the sky starts to rumble.
Common Questions
How do I prepare for a thunderstorm?
Secure outdoor objects that could blow away (furniture, umbrellas, trash cans), close windows, unplug sensitive electronics, and move indoors when you hear thunder. Maintain a NOAA weather radio with alert capability to receive severe thunderstorm warnings.
Where is the safest place during a thunderstorm?
A substantial building with plumbing and electrical wiring — which help direct lightning to ground — or a fully enclosed metal vehicle. Avoid using plumbing fixtures or plugged-in electronics while sheltering indoors. Avoid small sheds, open shelters, tents, and metal or water contact. Move inside at first thunder; stay inside for 30 minutes after the last rumble.
How close does lightning need to be to be dangerous?
If you can hear thunder, lightning is close enough to strike you. Lightning regularly strikes 10+ miles from a storm cell. Count seconds between flash and thunder: every 5 seconds = 1 mile. Under 30 seconds means you are in the danger zone.
Should I unplug electronics during a thunderstorm?
Yes for expensive or unprotected electronics. Surge protectors help but do not fully protect against direct lightning strikes. Unplug TVs, computers, and appliances during severe storms. Whole-house surge protection is a permanent solution for $200 to $500.
