  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
  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.

  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. 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.

  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.

  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 city centre.
  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. Nov 12, 2009Coastal Flood, Delaware Beaches$40.0 million
    National Weather Service narrative

    A powerful nor'easter produced wind gusts nearly as high as 60 mph, widespread moderate tidal flooding, heavy rain and severe beach erosion along the Delaware coast from November 12th through the 14th. Preliminary damage was estimated at 45 million dollars. The highest winds occurred from the morning of the 12th into the afternoon of the 13th. About 13,000 people in Delaware and Maryland lost power. The heaviest rain fell on the 11th and 12th. The combination of heavy rain and tides caused about 50 roads in Delaware to be closed, the most notable Delaware State Route 1. Parts of the roadway remain closed through the 15th as three feet of sand accumulated on it. Service on the Cape…

  2. Sep 18, 2003Tropical Storm, Inland Sussex$8.0 million
    National Weather Service narrative

    Tropical Storm Isabel caused tidal flooding up Delaware Bay, heavy rain and strong power outage producing winds. Isabel made landfall as a hurricane near Drum Inlet, North Carolina around 100 p.m. EDT on the 18th and weakened as it tracked farther inland. At one time in its life cycle, it was a powerful Category 5 hurricane when it was north of the Leewood Islands. Isabel's track took it west of Chesapeake Bay and was able to funnel water into the bay. This caused flooding along coastal areas all the way into New Castle County. Rivers and streams in New Castle County flooded from two fronts: from the heavy rain inland and also from the storm surge. The tide at Reedy Point reached…

    For the second time within a week a major winter storm, this one with blizzard conditions at times, affected the state of Delaware. Blizzard conditions occurred at times during the afternoon and early evening of the 10th. Accumulations averaged around one foot with the highest amounts in New Castle County. Ice accretions were less than one quarter of an inch. Two storm related deaths occurred. ||In the southern half of the state, precipitation started briefly as rain or sleet around 6 p.m. EST on the 9th.

    The most powerful storm to affect Delaware since the Blizzard of 1996 struck during the President's Day Weekend. Snow spread from south to north during the pre-dawn on Sunday the 16th. The heaviest snow fell during the daylight hours of the 16th. Precipitation started mixing with and changing to sleet from south to north during the evening of the 16th. In Sussex County, precipitation changed to freezing rain during the second half of the evening and even changed to plain rain toward and along the coast around midnight EST. Similar precipitation types fell overnight. Precipitation changed back to all snow before it ended during the day on the 17th in New Castle County. It remained…

  9. Aug 11, 2001Flash Flood$1.1 million
    National Weather Service narrative

    Slow moving thunderstorms with torrential rains inundated southwestern Sussex County during the late afternoon of the 11th. Doppler Radar storm total estimates reached 8.4 inches around Seaford. Aside from the far northeast and southeast part of the county, storm total estimates exceeded 3 inches in the rest of the county. The torrents led to flooding of streams and an eventual dam failure around midnight EDT on the 12th. About a dozen municipal streets were closed because of the flooding including Delaware State Route 20. About Midnight EDT, the 100 year-old dam on Hearns Pond gave way. The 60 acre pond drained out and a bulkhead along U.S. Route 13A was undercut by the flood…

  10. Feb 4, 1998Coastal Flood, Delaware Beaches$1.0 million
    National Weather Service narrative

    The strongest northeaster of the winter battered Kent and Sussex Counties with damaging winds, severe coastal flooding, extensive beach erosion, several dune breaches and heavy rain. A state of emergency was declared for all or parts of Sussex County from 7 a.m. EST on the 5th through 7 p.m. EST on the 7th. The county was declared a disaster area. Damage was estimated at about 1.7 million dollars and was the worst storm to affect the area since January 1992. Hardest hit communities included North Shore and South Bethany on the ocean side, Broadkill Beach on Delaware Bay and Long Neck in the back bay. About 3,000 persons evacuated including most of the permanent residents of Dewey…
