Tornado Risk in Musselshell County, MT
Musselshell County, MT: what NOAA's tornado record says
6 tornado tracks have crossed Musselshell County since 1986 by NOAA's count, roughly one every 12.7 years - the Minimal band on this site's scale. That is the 18th percentile nationally for tornado frequency. Within Montana alone, Musselshell County ranks 29 of 56 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Musselshell County in NOAA's 76-year database. Of its 6 recorded tracks, 5 were weak (EF0-1) and 1 significant (EF2-3).
Shelter and safe-room economics
Montana does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Musselshell 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 Musselshell County outright can still take its power out - outbreak-scale outages across Montana are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Musselshell County's figure does not tell you
Musselshell County's figure is county-wide, not address-specific. Musselshell County covers about 1,869 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. Musselshell County has about 5,452 residents.
