Hampshire County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Hampshire 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 WV GS (157), 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

   Incredible rainfall associated with the remants of Hurricane Fran caused considerable and in some cases record flooding along rivers and tributaries in the Potomac basin. A thin band of 11 to 14 inches of rain falling along higher ridges ran off into the Upper South Fork of the South Branch Potomac River and the Lost River sub-basin. These rain amounts led to record river flooding along the South Fork, Lost River, and Trout Run sub-basins.River flooding began simultaneously with the flash flooding in the Potomac Highlands. The flooding continued for nearly 48 hours before levels receded below flood stage. Crests were 1 to 5 feet above those of the January 1996 flood across the…

   A tornado descended on the 5100 block of Back Creek Road. Here, there was roof and siding damage to the house and outbuildings. On this farm property and to the east through unpopulated forest, thousands of trees were downed (80 to 90 percent at one point just east of property), many of which were hardwoods 1-2 feet thick snapped at the trunk.

   A powerful storm tracked across southern Hampshire County on July 12th, 2022, producing a 23-mile long by 9-mile wide swath of extensive tree and property damage. The vast majority of this damage was associated with a macroburst as a bowing storm and associated rear-inflow jet tracked across the county. Winds within this 9-mile wide swath were estimated to be between 60 and 105 MPH.||The storm progressed out of the North River Valley and crossed another range of mountains before progressing into the Cacapon River Valley. Here, numerous trees were snapped and uprooted in Yellow Spring, Capon Lake, and Capon Springs.

   A brief tornado caused damage at a farm on Arnold Farm Lane. Several snapped trees were noted in a tree-line a couple hundred yards to the west of the farm. An open-faced barn was destroyed; as this occurred, the roof of the barn was projected into the top of a silo, severely damaging the silo. A portion of a roof on another barn was dislodged, and the roof on the farmhouse was peeled up (but not removed).

   National Weather Service narrative

   On September 18, 2003, Hurricane Isabel made landfall on the North Carolina Coast. It moved northwest across Virginia and by 5 am on September 19, the center was over the heart of the eastern panhandle of West Virginia. Fortunately the storm had greatly weakened by this point. The heaviest rains appear to have been on the left side of the center track of the storm with the greater wind damage was to the right side. While sustained winds were no longer strong enough to do damage, the storm was still producing wind gusts in the 50 to 60 mph range. Previous rains had softened the soil and trees still had a full sail of leaves. Numerous trees uprooted onto power lines, roads, cars and…

   A residence on Buck Run had damage that was deemed to be tornadic. Downed trees fell across each other in a few spots on this property, and a video recorded on the property showed a circulation that passed through coinciding with the maximum winds.

    National Weather Service narrative

    The combination of an upper-level disturbance, increasing atmospheric shear, and ample instability set the stage for a major severe weather episode across portions of eastern West Virginia during the late afternoon and evening. The episode was highlighted by supercell thunderstorms which produced two multi-county tornadoes and several instances of large hail. For many residents of the Potomac highlands, the storms were a watershed event; the locals believed that tornadoes "like those in the midwest and Great Plains" could never strike.The first twister, originally associated with a supercell which had produced a long (11-13 mile track) tornado in Somerset Co, Pennsylvania,…
