Fairfax city

Every recorded tornado

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

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.

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).

1. Sep 18, 2003Tropical Storm, Fairfax$18.0 million
   National Weather Service narrative

   On September 18, 2003, Hurricane Isabel made landfall on the North Carolina Coast. Its huge wind field was already piling water up into the southern Chesapeake Bay. By the time Isabel moved into central Virginia, it had weakened and was downgraded to a tropical storm. Isabel's eye tracked well west of the bay, but the storm's 40 to 60 mph sustained winds pushed a bulge of water northward up the bay and its tributaries producing a record storm surge. The Virginia western shore counties of the Chesapeake Bay and the tidal tributaries of the Potomac, Rappahannock and other smaller rivers, experienced a storm surge which reached 5 to 9 feet above normal tides. In many locations,…

2. Apr 23, 1999Hail$2.0 million
   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…

3. Jan 19, 1996Flood, Fairfax$2.0 million
   National Weather Service narrative

   ***River Flooding***High dewpoint temperatures melted most of the snow on the ground within 12 hours. The snow pack had a liquid equivalent between 2 to 3 inches. Snowmelt, combined with 1 to 3 inches of rain (some locations received nearly 5 inches), caused the worst regional flooding in over 10 years. River flooding began during the flood/flash flood event along the headwaters of all basins and continued downstream through the 22nd. Crests ranged from 3 to 21 feet above flood stage.High water caused millions of dollars in damage, closed roads, destroyed homes and businesses, and forced the evacuation of several towns. Four people were rescued by the National Park Service and…

4. Nov 13, 2003Strong Wind, Fairfax$1.0 million
   National Weather Service narrative

   A strong cold front moved through the region early on the 13th, leaving behind frigid temperatures and strong winds. Widespread damage due to downed trees and power lines resulted. In Northern Virginia at least two people were injured. In Loudoun county, a student in Sterling was hit by a falling tree while waiting for the school bus, and a Leesburg man was struck by a large falling tree limb. A tractor trailer truck was overturned on Highway 81 in Shenandoah county. The driver was not injured. A poultry house was completely destroyed in Harrisonburg, and a bill board was blown down at the Winchester Regional Airport. At the height of the storm about 150,000 homes and business in…

   National Weather Service narrative

   Wind gusts of 58-63 mph were measured at Ft. Belvoir. There were trees down county wide. Sixty houses were damaged due to fallen trees and eighteen of them were inhabitable. One tree fell into a retention pond at a water treatment plant that caused damage.

6. Sep 7, 1996Flood, Fairfax$500,000
   National Weather Service narrative

   The rapid runoff produced by the heavy rains from Fran caused substantial, damaging, and in some cases record river flooding across much of the northern Virginia watershed from late on the 6th until early on the 10th. Flash flooding on the 6th rapidly became river flooding late on the 6th along the headwaters of the Potomac, Shenandoah, and Rappahannock River basins, and continued throughout the basins over the weekend and into early the following week. Crests at gaging points in these basins were similar to those in January 1996 across the Lower Main Stem of the Potomac. Levels were 1 to 5 feet higher across the Upper Main Stem Potomac and Rappahannock Rivers. The Shenandoah…

7. Feb 12, 2006Heavy Snow, Fairfax$200,000
   National Weather Service narrative

   A historic snowstorm occurred between February 11-12 across the Mid-Atlantic. Storm total snowfall across much of Northern and Central Virginia ranged generally between 8-14 inches. The highest snowfall totals occurred in the Northern Virginia suburbs of Washington, DC, where reports ranged up to 15 inches. There were also isolated reports of significant drifting of snow, mainly in and near Albemarle County. Finally, there were several instances of downed powerlines and trees due to the heavy snow. This caused significant power outages in some areas. Total power outages were reported to be around 300,000 customers around the Washington/Baltimore region. Amtrak reported major…

8. Mar 31, 1997Strong Wind, Fairfax$200,000
   National Weather Service narrative

   A nor'easter, languishing off the middle Atlantic coast, produced sustained winds between 25 and 40 mph with gusts to 50 mph or higher over much of northern Virginia. The winds caused scattered damage to buildings under construction, roofs, and trees and power lines. In Fairfax Co (VAZ053), damage included a partial unroofing of the Pickwick shopping facility in Centreville. Several businesses were closed during the cleanup, with one of the businesses, a video store, condemned. In Vienna, two partially constructed town homes sustained damage. One of the homes was nearly destroyed, and the other had its top level collapse.There were several damage reports from Arlington Co…

9. Aug 27, 2011Tropical Storm, Fairfax$150,000
   National Weather Service narrative

   About 100 trees were down. Most of the damage was in Springfield, Merrifield, Kingtowne, Annandale, and McLean. Numerous roads were closed due to downed trees and power lines. About 81,000 power outages were reported.

10. Jan 14, 2006High Wind, Fairfax$150,000
    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.
