Hackettstown

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Storm Prediction Center severe weather database, 1950 to 2025.

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

National Hurricane Center HURDAT2, 1851 to 2025.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges in Warren County, the county that contains Hackettstown.

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

The drought index is for Warren County, the county that contains Hackettstown.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the city centre.
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Mapped landslides

Landslides mapped in Warren County.

Mapped by NJ GS (44), NASA (1).

Deadly landslides

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

   National Weather Service narrative

   The remnants of Hurricane Ivan interacting with a slowly moving cold front caused widespread very heavy rain to fall during the first half of the day on the 18th in Warren County. Storm totals average 3 to 6 inches with locally higher amounts throughout the county. The torrential rain caused widespread poor drainage, creek and river flooding. Runoff from the heavy rain also caused the worst flooding along the Delaware River since 1955. President George W. Bush declared the county a disaster area. Damage was estimated at twenty-eight million dollars.The Delaware River washed a home from Harmony Township (Warren County) downstream. The home crashed into the Easton-Phillipsburg Free…

   Several days of heavy rain throughout the Delaware River Basin culminated with major flooding along the Delaware River from the 28th through the 30th. It was the second to fourth highest crest on record for the Delaware River along Warren County. The crest was slightly lower than the April 2005 flood in Belivdere and Phillipsburg, but the second highest on record (since 1955) at Tocks Island. President George W. Bush declared Warren County a disaster area. Sporadic periods of heavy rain started on the 23rd, but the most widespread and heaviest rain fell from the night of the 27th into the morning of the 28th. Event totals in Warren County averaged three to eight inches, but storm…

   Post Tropical Storm Sandy was the costliest natural disaster by far in the state of New Jersey. Record breaking high tides and wave action combined with sustained winds as high as 60 to 70 mph with wind gusts as high as around 90 mph to batter the state. Statewide, Sandy caused an estimated 29.4 billion dollars in damage, destroyed or significantly damaged 30,000 homes and businesses, affected 42,000 additional structures and was responsible directly or indirectly for 38 deaths. A new temporary inlet formed in Mantaloking (Ocean County) where some homes were swept away. About 2.4 million households in the state lost power. It would take two weeks for power to be fully restored to…

   Hurricane Floyd battered New Jersey (especially the central and northern thirds) on September 16th and brought with it torrential and in some areas, unprecedented and record breaking rains and damaging winds. The hurricane will go down in history as the greatest natural disaster to ever effect the state of New Jersey to date. Preliminary damage estimates for the entire state were 1.1 billion dollars hitting Bergen and Somerset Counties the hardest. Manville and Bound Brook were hardest hit within Somerset County. Six persons died in the state; all drownings: two each in Somerset and Bergen Counties, one in Passaic County and one in Salem County. Hundreds were injured. The…

The worst damage occurred along the Delaware River which crested at its highest stages in most places since the summer of 1955. Widespread flooding along the Raritan was described as the worst in Manville since Tropical Storm Doria in August 1971. Damage estimates exceeded $10 million dollars including $2 million dollars at the Delaware Water Gap National Recreational Area. Only one person was seriously injured (hypothermia) in Raritan Township in Hunterdon County.

   The heavy rain caused several creeks and streams to flood in Warren County and forced the closure of eighteen major roadways. Even westbound Interstate 80 was closed in Knowlton Township because of a rockslide. There was one minor accident when this occurred. In Blairstown both the Paulins Kill and Blair Creek flooded.
