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

  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.

  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. 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

    Training thunderstorms dropped an estimated 4 1/2 to 6 inches of rain onto previously saturated soil, producing widespread flooding. Mud and rock slides were common along federal highway 220, and other large rocks were found on local route 678. Evacuations were ordered in Mustoe, where local route 607 washed out. The evacuations were prompted by 2 inches of rain in a 2 hour period which brought streams and creeks rapidly out of their banks.Nearly all basements received some degree of flooding in Mustoe, and numerous others were flooded in Monterey.

    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.

    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.

  8. Mar 28, 1996Ice Storm, Highland$30,000
    National Weather Service narrative

    A strong surface high pressure area over New England pushed a shallow layer of subfreezing air into the Shenandoah Valley early on the 28th. An inverted trough of low pressure west of the Appalachians promoted overrunning of warm moist air, which eventually produced light to moderate precipitation. The precipitation fell as rain higher than 2000 feet and below 500 feet above mean sea level; between 500 and 2000 feet, where temperatures were as low as 28°F, the precipitation froze on contact.Numerous trees and power lines were knocked down at these elevations in the western Shenandoah Valley, mainly during the late evening of the 28th and early morning of the 29th. Problems began,…

    National Weather Service narrative

    Gusty winds in excess of 40 mph, combined with soft soil from previous rainfall, caused scattered tree damage across much of the Virginia Piedmont and a small area of the coastal plain. At elevations above 2000 feet, sustained tropical-storm force winds with gusts as high as 79 mph pummelled the landscape, especially the east-facing slopes of Shenandoah National Forest and the George Washington National Forest. Thousands of mainly light wood trees (pines and maples) were snapped or uprooted. Along Skyline Drive alone, over 500 trees had to be cleared from the roadway before it could be reopened. Numerous trails had trees down; some trails remained closed more than one month after…
