Tornado Risk in Ferry County, WA
Ferry County's tornado history, by the numbers
1 tornado track have crossed Ferry County since 2008 by NOAA's count, roughly one every 76.9 years - the Minimal band on this site's scale. That is the 5th percentile nationally for tornado frequency. Within Washington alone, Ferry County ranks 28 of 39 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Ferry County in NOAA's 76-year database. Of its 1 recorded tracks, 1 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
Washington does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Ferry County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
The storm that misses Ferry County outright can still take its power out - outbreak-scale outages across Washington are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Ferry County's figure does not tell you
Ferry County's figure is county-wide, not address-specific. Ferry County covers about 2,203 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. Ferry County has about 7,543 residents.
