Greene County

Every recorded tornado

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

National Hurricane Center HURDAT2, 1851 to 2025.

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 (3), NASA (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.

   National Weather Service narrative

   An intense area of low pressure which was located over the Mid-Atlantic region on Friday morning January 19th produced unseasonably warm temperatures, high dewpoints and strong winds. This resulted in rapid melting of one to three feet of snow. In addition to the rapid snowmelt one to three inches of rain fell as the system moved northeast along the coast. This resulted in widespread flooding across Greene County. Federal Disaster Assistance was made available by presidential declaration. Small streams flooded across the entire county which resulted in many roads being washed out. Extensive flooding also occurred along the Hudson River and Schoharie Creek. In Athens, Coxsackie and…

   National Weather Service narrative

   The remnants of Hurricane Floyd moved up the eastern seaboard on September 16 and during the early hours on September 17. The storm brought both high winds and exceptionally heavy rainfall to eastern New York, which included a large swath of 3 to 6 inch amounts. A frontal zone helped concentrate the heaviest rain just to the west of the Hudson Valley in the eastern Catskills and Helderbergs . Locally higher amounts of rainfall, exceeding a foot, fell in these areas. Specific rainfall amounts included 6.12 inches at Albany International Airport, the highest ever officially recorded from any given storm! Even higher amounts of rainfall included 8.15 inches in Delmar and 9 inches at…

4. Jul 21, 2003Tornado$1.0 million
   National Weather Service narrative

   A large upper air trough dug across the western Great Lakes on Monday, July 21. At the surface, a deep low pressure area moved across the eastern Great Lakes, driving a warm front across eastern New York and adjacent New England. The air became very unstable in the warm air mass behind the front. The combination of the unstable air and strong wind shear aloft, produced the most significant severe outbreak of the season across the region, and the largest tornado outbreak since May 31, 1998. The first line of thunderstorms worked across the region during the afternoon hours. These produced spotty wind damage, mainly downed trees and wires across portions of Albany, Greene,…

5. Mar 31, 1997Winter Storm, Western Greene$1.0 million
   National Weather Service narrative

   On March 31 and April 1, a classic late season nor'easter tracked from the Chesapeake Bay area northeast to central coastal New Jersey then slowly out to sea. This system produced rain across much of eastern New York during the morning hours of March 31. The rain changed to heavy wet snow by early afternoon. Heavy snow fell over eastern New York from the Mohawk Valley southward. Snowfall amounts were highly elevation dependent. Snowfall exceeded 2 feet in many mountain locations. Some specific snowfall totals included: 15 inches at the Albany Airport, 26 inches at Berne in Albany County, 9 inches at Rotterdam in Schenectady County, 11 inches at Poestenkill in Rensselaer County, 10…
