Tornado Risk in Somerset County, NJ

The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Somerset County in NOAA's 76-year database. Of its 5 recorded tracks, 3 were weak (EF0-1) and 2 significant (EF2-3).
Shelter and safe-room economics
New Jersey does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Somerset County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in New Jersey often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Somerset County's figure does not tell you
Somerset County's figure is county-wide, not address-specific. Somerset County covers about 302 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. Somerset County has about 357,467 residents.
