Keep Outdoor Events Lightning-Safe
Original preparedness explainer · Reviewed as a draft October 29, 2026 · General U.S. guidance
Picnics, sports and community fairs need a decision rule before thunder starts. Organizers can reduce confusion with a named weather watcher.
Choose an actual shelter building in advance, count how long it takes to reach it and communicate the stop-play rule to everyone.
The National Weather Service recommends waiting at least 30 minutes after the last thunder before resuming outdoor activity.
The safest response to nearby thunder is prompt shelter in a substantial building or enclosed hard-topped vehicle. Avoid windows, plumbing and corded electrical devices during close lightning.
