Nelson County

Every recorded tornado

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

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

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.

NOAA NCEI nClimDiv county Palmer Drought Severity Index, 1895 to September 2026, issued October 6, 2026.

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 (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.

   At 4:37 AM EST this morning on I-64 at mile marker 100 (near summit of Afton Mountain/Blue Ridge; approximately 4 miles SE Waynesboro, VA), a tractor trailer lost control and overturned. A tour bus was unable to stop and impacted the truck. Several other minor accidents ensued. The culprit is likely black ice due to freezing drizzle. EM confirmed 21 transports to hospitals, with injuries ranging from minor to serious.

   Thunderstorms with heavy rainfall, gusty winds, and frequent lightning moved through the southern Shenandoah Valley during the evening of the 5th. In Augusta County, a power transformer was damaged by lightning resulting in the loss of power to 4600 residents. Another bolt started a garage fire near Dooms. In Waynesboro, a felled tree branch downed a power line. Heavy downpours flooded city streets. In Albemarle County, high winds downed trees between 10 and 15 miles from Keene. Pea sized hail was reported near Charlottesville. Heavy downpours flooded low lying areas and Route 20 was covered in water. In Nelson County, high winds downed a tree on Wilson Road. Heavy downpours…

   By 9 pm on September 18, a rain band associated with Isabel had set up over the Shenandoah Valley and showers were training southward into the Blue Ridge Mountains on the east side of Augusta County. The rain gauge located at Upper Sherando had recorded over 6 inches of rain and more was to come. County officials quickly began evacuations of homes downstream. In all 350 people in the South River area would be evacuated and 21 of those ended up being by boat. Water flowed down the Black Creek at 60 mph washing out the bridge and several hundred feet of asphalt along Route 608. Four spillways to dams flooded causing damage but none of them failed. There was $125,000 damage to the…
