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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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.

  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).

    National Weather Service narrative

    A line of thunderstorms developed in West Virginia during the early afternoon and moved rapidly southeast across Northern Virginia. These storms produced very large hail in a 10 mile wide strip from Winchester in Frederick County to Woodbridge in Prince William County from 3:30 PM EDT to 5:00 PM EDT. Winds over 55 MPH also downed trees and power lines in Frederick and Clarke County between 3:30 PM EDT and 4:15 PM EDT. Frederick County spotters reported between 1 3/4 to 3 1/2 inch diameter hail. The rubber membrane roof of the War Memorial Building in Winchester was punctured by hail the size of golf balls, allowing heavy rain to fall inside the structure and cause significant…

    National Weather Service narrative

    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…

  4. Jan 14, 2006High Wind, Frederick$100,000
    National Weather Service narrative

    Very strong winds developed on the 14th due to a strengthening low pressure system off the Mid Atlantic Coast and a fast moving cold front that passed through the region early in the day. Widespread damages and power outages occurred, with newspaper reports indicating tens of thousands without power for an extended period of time.

  5. Jul 17, 2021Thunderstorm Wind$100,000

  8. Jan 7, 1996Blizzard, Frederick$35,000
    National Weather Service narrative

    An historic winter storm, known as the "Blizzard of '96", crippled all of northern Virginia during the first full weekend of January. In general, snow totals ranged from 20 inches on the coastal plain (VAZ052>53; 055>057) to over 3 feet at the higher elevations of the central and northern Shenandoah Valley. To complicate matters, winds gusting in excess of 35 mph produced drifts of 4 to 7 feet, except over 10 feet in the mountains. The storm produced the largest statewide storm totals since the "Megalopolitan Storm" of February 11th, 1983. Numerous 24-hour accumulation records were shattered at airports from southwest Virginia through New England; Washington/Dulles airport (IAD;…

  9. Jun 22, 2022Thunderstorm Wind$30,000
    National Weather Service narrative

    A couple dozen trees and wires blew down across the City of Winchester.

  10. Jun 29, 2012Thunderstorm Wind$25,000
    National Weather Service narrative

    A strong upper-level disturbance passed through the region in a northwest flow aloft. Extremely hot and humid conditions caused high amounts of instability. The upper-level disturbance triggered a line of thunderstorms that moved through the area. Due to the high instability, thunderstorms caused widespread wind damage.

  1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
