Start with the complete St. Louis storm shelter guide — risk, house type, shelter type, standards, cost, money, permits and installation, in that order. The guides below answer the questions St. Louis households ask before choosing a shelter: how real the risk is here, what fits a St. Louis house, and what it costs and takes to install. Each is dated and tied to public sources.
The risk here
- The May 16, 2025 St. Louis tornado — the path, the NWS surveys, the siren failure and what changed, recovery orders, and what it means for sheltering.
- St. Louis tornado history and risk — 1896 to 2025, the north County corridor hit in 1967 and 2011, and why evening and winter matter.
- Household tornado plan — sirens, NotifySTL and county alerts, weather radio, a night drill and a kit.
- Mobile home tornado safety — why to leave, what to ask your park, and shelter options.
