NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.

Between 1950 and 2026, NCEI recorded 397 storm events in Passaic County, New Jersey, led by floods and flash floods.

That is 213.4 events per 100 square miles, below the New Jersey figure of 358.7, and 7.7 per 10,000 residents against 28.5 statewide.

8 events fall in the 12 months to 30 Jun 2026. NCEI attributes 8 deaths and 18 injuries to events in the county, with property damage estimated at $25M.

Recorded events in Passaic County by decade and hazard group. HailTornadoFloodWindLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 263 events in the 20 years to 2025 against 126 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
