The situation
Your weather monitoring app sends a push alert: TORNADO WARNING for your county. 15-minute estimated impact window. You're standing in the middle of a park with 5,000 people, food trucks, a main stage with live band, inflatable attractions for kids, and two permanent buildings within 500 yards — a recreation center with interior windowless corridors and locker rooms (capacity 2,000) and a brick community hall with a basement level (capacity 1,500).
First moves and what each one costs
- Cut the music immediately, use the PA to announce tornado warning and direct people into the rec center's interior rooms and the community hall basement — away from windows, never to the parking lot — in a calm, authoritative tone — People are startled but the authority in the announcement gets them moving. Some panic but staff are directing traffic. Both buildings start filling within 3 minutes.
- Radio all staff to begin quietly guiding people toward buildings without making a public announcement, to avoid panic — Staff start guiding nearby people, but 5,000 people can't be quietly moved. Most don't know what's happening. Families are scattered across a large area. You're losing critical minutes.
- Monitor the weather radar for 5 more minutes to confirm the threat before disrupting the event — 5 minutes pass. The sky turns green. Now you have 10 minutes and people are noticing the weather themselves. Some start running to their cars — the most dangerous place to be in a tornado.
Preparation notes for this situation
- Always have a weather monitoring plan and designated weather watcher
- Never shelter people in parking garages, tents, or any large open-span building — use small interior rooms on the lowest floor, away from windows
- Know your venue's severe weather shelter capacity BEFORE the event
- Practice shelter announcements — clear, calm, specific instructions move people faster than urgency alone
- Have a relationship with local emergency management before your event
