What a storm shelter costs near Harmon County
Oklahoma's SoonerSafe Safe Room Rebate Program is the number that matters for a Harmon 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 outage nobody plans for
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.

This is a county-level figure, not a per-address probability. Harmon County covers about 537 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. Harmon County has about 2,315 residents.
