Steuben County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Steuben County: 1.
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 USGS Conterminous (8).

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.

   The first indications of severe flooding occurred in the southwest portion of the Steuben county at around 145 pm EST from excessive rainfall. Over two days, between 6"-8" of rain fell in a southwest to northeast band across the southern half of the county. 2 to 4 inches of rain fell from nearly stationary thunderstorms in less than 3 hours during the early afternoon. Several rounds of thunderstorms went through on the 21st and 22nd. More than 20 state, county and town roads were closed or impassible including Interstate 86. Steuben County along with the Town of Campbell and Village of Arkport declared States of Emergency and requested no unnecessary travel. Interstate 86 was…

   The most disastrous flood event in more than twenty years struck central New York from the early morning of the 19th to the evening of the 21st. Significant widespread flooding of streams, rivers, homes and businesses, streets and highways, woodlands, and farmland occurred as a result of rapid snowmelt and nearly simultaneous storm runoff. Every county in central New York experienced road closures due to washouts, mudslides, and failed, damaged, or weakened bridges. There were six known fatalities. In Delaware County, five occupants of one car were killed when their vehicle and three others were swept into the Cannonsville Reservoir. A roadway over a sluice from an upstream pond…

Rainfall amounts from the 8th into the 9th were 2.5 inches to around 5 inches in southeast Steuben County. The heavy rain was aided by tropical moisture from the remnants of hurricane Frances. Many streams and creeks were out of their banks. Several bridges were washed out or damaged beyond repair. The Freeman Bridge on County Route 85 near South Addison buckled when the foundation was disturbed. School was cancelled in a few towns. The worst hit area was along Route 417 and the Tuscarora Creek in the towns of Woodhull and Tuscarora. The road was…
