The number that matters more than frequency

Shelter and safe-room economics
Oklahoma's SoonerSafe Safe Room Rebate Program is the number that matters for a Grant 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.
Power after the storm, not just shelter during it
A direct hit is not required for Grant County to lose power - outbreak-wide outages across Oklahoma regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What Grant County's figure does not tell you
Grant County's figure is county-wide, not address-specific. Grant County covers about 1,001 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Grant County has about 4,123 residents.
