Paying for it, if Delaware County's history says you should
Oklahoma's SoonerSafe Safe Room Rebate Program is the number that matters for a Delaware County homeowner: 75% of an approved shelter, capped at $3,000, cutting the typical $2,890-$13,280 national range to about $722.5-$10,280 net. Lottery-based; no confirmed 2026 FEMA funding round per local reporting - check current status before assuming it is open.
The gap a shelter does not cover
Tornado outbreaks routinely knock out power across Oklahoma for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Delaware County covers about 738 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Delaware County has about 41,771 residents.
