Broome County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Broome County: 0.
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.

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.

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

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.

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 county boundary (or inside the county).
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

Mapped by NASA (2), USGS Conterminous (1).

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.

1. Jun 27, 2006Flash Flood$200 million
   National Weather Service narrative

   Tropical moisture streaming into upstate New York ahead of a frontal system which moved westward into the eastern Great Lakes by Tuesday morning the 27th started the flash flood problems in western Broome County early Tuesday. The rain abated for a time during the day Tuesday before another batch of heavy rain fell Tuesday afternoon into Wednesday morning as the front moved back east and combined with a low pressure system moving up the eastern seaboard. This scenario spelled disaster for Broome County. Total rainfall for the three day period ending Wednesday was up to 9 inches, especially in the Conklin and Windsor areas, which were particularly hard hit. This additional heavy…

2. Sep 7, 2011Flood$170 million
   National Weather Service narrative

   A record flood occurred at the Binghamton/Washington St. bridge river gauge in Binghamton, NY. The crest was 25.71 feet at 3:00 PM on September 8, 2011. The flood waters topped the flood protection walls and levees, causing extensive flooding throughout the downtown areas of Binghamton. This surpassed the previous record of 25.0 feet set during the June 2006 flood.

3. Sep 7, 2011Flood$160 million
   National Weather Service narrative

   Record flooding occurred between September 7, and September 11, 2011 along the Susquehanna river at Vestal, NY. According to the stream gauging station at Vestal, the river crested at 35.26 feet at Noon on September 8th. This surpassed the previous record of 33.66 feet set during the June 2006 flood.

4. Jun 27, 2006Flood$50.0 million
   National Weather Service narrative

   The Vestal river gage on the Susquehanna River is located 8 miles west of the Binghamton Washington Street Gage. Vestal is on the left bank of the river and the Town of Union Communities of Johnson City, Endwell and Endicott are on the right bank of the Susquehanna River. Each community had extensive flood losses, too numerous to list. Some of the more notable losses are the many homes in areas like the Castle Gardens development which were recovering from losses due to the April 2005 flooding. The inundation of the Enjoi Golf Course forced the cancellation of the "BC Open", a PGA Tour Event. This was a further economic blow for many businesses in the region. The Vestal gage…

9. Jul 3, 2025Hail$20.0 million
   National Weather Service narrative

   There was an exceptional swath of hail damage, approximately 2.5 miles wide and 5 miles long. Many trees were completely stripped of their foliage, including an entire hillside, which bore the brunt of the storm and appeared entirely bare. Widespread hail damage was also reported to vehicles and homes within the affected area. Spotters reported golf ball sized hail. The hail accumulated in some areas making the ground white and roads slippery.

    Major flooding occurred on the Susquehanna River near Windsor, NY. The river crested at 24.21 feet on September 8, 2011 at 6:45 PM.
