District of Columbia

Every recorded tornado

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

High tide flooding

1. High tide flooding days are days on which a NOAA tide gauge recorded water at or above NOAA's minor flood threshold, set from the gauge's tide range, counted by meteorological year (May to April). These are the counts in NOAA's annual high tide flooding reports; they are not National Weather Service flood stages. Years with less than 80 percent of data are left out.

NOAA CO-OPS high tide flooding counts, through April 2026, retrieved October 30, 2026.

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 NASA (2).

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.

1. Sep 18, 2003Tropical Storm, District Of Columbia$125 million
   National Weather Service narrative

   Hurricane Isabel shut down Washington, DC on Thursday September 18 and Friday September 19. The city had days of preparation and many people including non-emergency government personnel were told to stay home. Tropical storm force winds spread north into the area by 4 pm. Because air temperatures were cool (in the 60s) and the peak of the storm occurred near midnight, the real hurricane force winds were a few hundred feet up. Wind sensors on building tops recorded 70 to 85 mph hour winds. At the surface, winds were about half of that, but occasional strong gusts would mix down from above and damage trees and power lines. Winds began to subside falling below tropical storm by 4 am…

2. Jul 29, 2023Thunderstorm Wind$20.0 million
   National Weather Service narrative

   A wind gust of 73 knots (84 MPH) was measured by a mesonet at the George Washington University Mount Vernon Campus (1855W). Thousands of trees, branches, wires and poles blew down in Palisades, Wesley Heights, Cathedral Heights, Woodley Park, Observatory Circle, Foxhall Village, Adams Morgan, Cleveland Park, and DuPont Circle, including dozens onto cars, homes and businesses. Several apartment buildings lost their roof, including along Wisconsin Avenue Northwest; other homes particularly in the Wesley Heights neighborhood suffered roof and siding damage from the wind. A large tree blew down onto an SUV on Foxhall Road Northwest, injuring two occupants. The National Zoo was closed…

3. Jan 20, 1996Flood, District Of Columbia$10.0 million
   National Weather Service narrative

   *** Potomac River Flooding ***High dew point temperatures melted the entire snow pack within 12 hours, with liquid equivalents averaging 1 to 2 inches. Snowmelt combined with 1 to 3 inches of rain caused the worst regional flooding in over 10 years. No tidal variations were noted once the stage surpassed 10 feet. The river crested at 13.88 feet (Wisconsin Avenue in lower Georgetown) on the 21st, dropping below flood stage (7 feet) by the 23rd.River flooding in the city was limited to Georgetown, Foggy Bottom, and the Haines Point/Washington Marina area. High water forced the closure of some waterfront property for several days, damaged homes and businesses, and brought heavy…

4. Jun 25, 2006Flash Flood$10.0 million
   National Weather Service narrative

   A weak cold front settled over the forecast area from June 23 until June 27. Waves of low pressure rode northeast along the front. Flow in the atmosphere was parallel to the boundary, producing several rounds of training echoes. As a result, double digit rainfall totals affected parts of the region through the five days. There were also several rounds of severe weather with damaging winds and large hail during the period.A slow-moving line of thunderstorms fired along a tropical moisture plume and dumped between 4 and 7 inches of rain in Washington DC, causing extensive urban flooding on June 25 and June 26. Washington National Airport recorded more than 10 inches of rain, with…

5. Aug 11, 2001Flash Flood$6.0 million
