Tornado Risk in Weber County, UT
Weber County, UT: what NOAA's tornado record says
8 tornado tracks have crossed Weber County since 1968 by NOAA's count, roughly one every 9.5 years - the Low band on this site's scale. That is the 25th percentile nationally for tornado frequency. Among 29 Utah counties in this dataset, Weber County ranks 6 for how often a tornado touches down.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Weber County in NOAA's 76-year database. Of its 8 recorded tracks, 6 were weak (EF0-1) and 1 significant (EF2-3).
Shelter and safe-room economics
Utah does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Weber County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Tornado outbreaks routinely knock out power across Utah 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.
What Weber County's figure does not tell you
Weber County's figure is county-wide, not address-specific. Weber County covers about 611 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. Weber County has about 276,118 residents.
