The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Haines Borough in NOAA's 76-year database. Of its 0 recorded tracks, 0 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
Alaska does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Haines Borough 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 Alaska 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 Haines Borough's figure does not tell you
Haines Borough's figure is county-wide, not address-specific.
