Kinnelon

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 Morris County, the county that contains Kinnelon.

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 Morris County, the county that contains Kinnelon.

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 Morris County.

Mapped by NJ GS (32), NASA (6).

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.

   Morris County was greatly effected by flooding from Irene, especially along the Passaic and Pompton Rivers. |In Dover Township, a construction worker fell off a bridge, was washed away and drowned in the Rockaway River. About 4,000 homes in the county were affected by flood waters in Pequannock, Lincoln Park, Dover, Parsippany and Denville. The flooding along the Rockaway River forced the collapse of the northbound Interstate 287 roadway shoulder in Boonton. All northbound lanes remained closed until August 30th.

   A nearly unprecedented thunderstorm with torrential downpour remained nearly stationary for about six hours from 9 a.m. EDT through 3 p.m. EDT on August 12th over the Hamburg Mountains of eastern Sussex County. Doppler Radar Storm total estimates reached around 15 inches along the Sussex/Morris County border. Two to three inches of rain fell per hour in the strongest storms and caused considerable, widespread and devastating flooding across southeastern Sussex County and western Morris County. Mud and rock slides exacerbated the damage. This was approximately a one in a thousand year event. About 2,700 homes and businesses were flooded. Eight houses were totally destroyed, about…

    Very heavy rain caused poor drainage flooding as well as minor to moderate flooding in the Passaic Basin. Some of the flooding along the Passaic River did not start until May 1st. That flood information is included below and will be repeated in May's stormdata entry. In Roxbury Township, the exit ramps in both directions off of U.S. Route 46 were flooded and closed. The heavy rain forced emergency repair lane closures on Interstate 287 in Parsippany-Troy Hills and Morristown. Mass transit was not immune. Service was suspended along a section of New Jersey Transit's Montclair-Boonton Line until May 5th as workers repaired a track washout. Buses were made available to shuttle…
