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

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.

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. 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.

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).

  1. Sep 1, 2006Coastal Flood, Northumberland$19.7 million
    National Weather Service narrative

    Tides of 4 to 5 feet above normal...combined with 6 to 8 foot waves caused significant damage to homes, piers, bulkheads, boats, and marinas across portions of the Virginia's Northern Neck and Eastern Shore near the Chesapeake Bay, Atlantic Ocean and adjacent tributaries. Some of the most significant damage occurred in the Lewisetta area of Northumberland county.

  2. Sep 1, 2006High Wind, Northumberland$15.0 million
    National Weather Service narrative

    The remnants of Ernesto along the Mid Atlantic coast combined with strong high pressure over New England produced very strong winds across eastern and southeast Virginia. Sustained winds in mph ranged from the lower 40s to near 60 with maximum gusts ranging from the mid 50s to as high as the mid 70s. Some higher sustained winds included 60 mph (52 knots) at York River Range Light and York River United States Coast Guard, and 56 mph (49 knots) at Wallops Island (WAL). Some higher maximum gusts included 76 mph (66 knots) at York River Range Light, and 75 mph (65 knots) at York River USCG. The high winds caused numerous downed trees and power outages, along with significant…

  3. Aug 4, 2020Tornado$626,000
    National Weather Service narrative

    A damage survey conducted by the NWS Wakefield office found a path of storm damage consistent with an EF1 tornado. The tornado moved onshore from the Chesapeake Bay in the town of Fleeton, crossing Fleeton Road where several houses experienced roof and siding damage. In addition, trees were snapped and uprooted. The tornado then crossed over the Wicomico River and then moved back onshore near Timbs Road where trees were uprooted and snapped, and a few houses experienced roof and siding damage. The tornado then moved northward to near Buzzards Point Road, destroying a canopy, before lifting.

The center of the storm crossed the county warning area along an Elizabeth City to Currituck county to Sandbridge Virginia Beach axis. The highest sustained wind speed recorded was 69 mph at Chesapeake Light (CHLV2). Other sustained wind speeds were 46 mph at Langley Air Force Base (LFI), 44 mph at Norfolk Naval Air Station (NGU), and 41 mph at Oceana Naval…

  5. Nov 12, 2009Coastal Flood, Northumberland$500,000
    National Weather Service narrative

  6. May 3, 2021Tornado$500,000
    National Weather Service narrative

    A tornado touched down along Richmond Road (Route 360) just southwest of Callao. The tornado was EF0 intensity at its beginning as it tracked northeast crossing Lakeside Drive just east of Callao. The tornado then crossed Northumberland Highway (Route 360), intensifying as it approached Chambers Lane. The tornado quickly reached EF2 intensity as it crossed Chambers Lane destroying one home and damaging several others. The destroyed home was built in the 1970s and based on builder inspector data was constructed to withstand 100 mph wind. In this same area, another home lost its garage causing severe damage to the home. In this area, winds were estimated around 120 mph at the…

  7. Apr 3, 2024Tornado$274,000
    National Weather Service narrative

    A tornado tracked from Richmond County across Ridge Road and into Northumberland County where it caused mainly EF-0 damage to Quinton Oaks Gulf course as several hardwood trees were knocked down along with a storage shed which was destroyed. Additional damage was caused to a double wide manufactured home off of Ridge Road which had large sections of its roof ripped off. The tornado then intensified as it crossed Azalea Lane and Owl Town Road where numerous hardwood trees were snapped along with two houses which had portions of their roofs lifted off. One of these houses had its garage wall blown out and the other had multiple walls collapse and cave in. The damage in this area was…

    National Weather Service narrative

    Tornado damage occurred from Burgess to Oyster Cove. The most significant damage was found in the Edwardsville area, where nearly 20 mobile homes were severely damaged or destroyed. Numerous trees were downed or suffered damage. Nine, mostly minor, injuries were reported.

  9. Oct 28, 2012Coastal Flood, Northumberland$200,000
    National Weather Service narrative

    Water levels reached 2.0 feet to 3.5 feet above normal adjacent to the Chesapeake Bay and Potomac River resulting in moderate to severe coastal flooding.

  10. Oct 28, 2021Coastal Flood, Northumberland$200,000
    National Weather Service narrative

    Strong low pressure tracked from the Middle Mississippi Valley east northeast toward the Northeast United States from Thursday, October 28th into Saturday, October 30th. This system produced very strong east southeast winds, then strong south to southwest winds through the period. This caused moderate to major (tidal) coastal flooding across portions of Northumberland county adjacent to the Potomac River. Lewisetta reached 4.78 feet MLLW at 900 pm on Friday, October 29.
