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

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.

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.

  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. 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. Apr 4, 1997Blizzard, Dickey$1.5 million
    National Weather Service narrative

    Warm weather the first three days of April lead much of North Dakota to believe that spring had arrived with temperatures in the 60s and 70s. Mother Nature had other plans. A very strong area of low pressure moved out of the Colorado area into the northern plains. Warm moist air ahead of the low collided with cold air coming down from Canada. The result was the worst blizzard of the season for North Dakota, bringing much of the state to a complete halt. The precipitation began to fall during the afternoon of the 4th (Friday), as rain in the east and freezing rain or sleet in the west. By Friday evening the freezing rain and sleet had changed over to all snow in the west. By…

  2. Jan 9, 1997Blizzard, Dickey$1.5 million
    National Weather Service narrative

    The second blizzard in less than 1 week brought North Dakota to a virtual standstill. This blizzard didn't bring as much snow as the first storm, but the winds gusted from the northwest as high at 40 mph and they lasted for 3 days. Snowfall amounts from this storm varied from 1-2 inches in the southwest to 2-4 inches in the central. But the strong winds combined with this snow as well as the snow from the blizzard a few days earlier created widespread whiteout conditions that lasted for 3 days. There were numerous communities that halted mail delivery and cancelled school. In Emmons Co. every road was blocked by drifts, some as high as 18 feet. In McLean Co. there was a drift at…

  3. Jul 10, 2011Thunderstorm Wind$1.3 million
    National Weather Service narrative

    A National Weather Service Storm Survey was conducted across Dickey County. Widespread mature hardwood trees were snapped or uprooted along a 45 mile long and 4 mile wide damage swath, along with thousands of acres of crop damage due to wind driven hail. Several communities along the damage path also had severe wind damage. Near Merricourt, damage was observed to a home and to several farm vehicles. In Monango, extensive tree damage was observed, including a large hardwood tree with the diameter of 22 inches. A pole barn and two grain bins were destroyed two miles south of Fullerton, along with several large trees snapped or uprooted. Around Oakes, numerous buildings sustained…

  4. Dec 25, 2023Ice Storm, Dickey$1.0 million
    National Weather Service narrative

    Around 400 utility poles were broken, along with multiple cross-members. Many miles of power lines throughout the county were down. Power service was out over most of the county at some time during the storm. Travel became nearly impossible given the icy conditions.

  5. Jun 14, 2022Thunderstorm Wind$1.0 million
    National Weather Service narrative

    Extensive damage occurred throughout the city of Ellendale and surrounding areas. In Ellendale, many hardwood trees were snapped and others were uprooted, some falling onto homes. A home had almost all the shingles and much of the sheathing torn off the roof, and the garage door was collapsed inward. Some power poles were broken in town, and several power service lines to homes were torn. South of Ellendale to the South Dakota state line, multiple power poles were snapped. At the Ellendale Cemetery, multiple hardwood and softwood trees were snapped and others were uprooted. In parts of Ellendale, ping pong ball size hail accompanied the storm.

  6. Jan 15, 1997Blizzard, Dickey$900,000
    National Weather Service narrative

    The 3rd blizzard to hit North Dakota in less than 3 weeks affected mainly the east-central and eastern part of the state. Again, like the previous blizzard, the winds was the major weather factor. Wind gusts at times were over 50 mph. This created widespread blowing and drifting snow. All major roads in the area were closed again for the 3rd time this year. In Logan Co. the machine shed that is used by the Logan Co. Historical Society to store antiques was damaged by the roof falling in. With the severity of the blowing and drifting snow, roads that were just opened from the last storm were once again blown shut. This lead to the death of a 71 yr. old Fredonia(Logan Co.) man. He…

    The last in a string of 4 blizzards to hit North Dakota struck in the morning of the 22nd. Snow amounts with this storm ranged from 2-4 inches, but northwest winds gusted to near 45 mph. Again, east-central and eastern North Dakota were hardest hit. I-29 in North Dakota and I-94 from Bismarck to Fargo were closed again. Injuries and damage amounts estimated.

  9. Jun 7, 2005Flash Flood$750,000

    A foot of water reported over many roads destroying several county and township roads. Several fences washed out.

  10. Dec 25, 2016Ice Storm, Dickey$750,000
    National Weather Service narrative

    Ice accumulation caused multiple power poles to snap throughout the county. Near one wind farm, 64 double poles supporting the feeder line were snapped in a three mile stretch. Repairs for this continued as of the end of February 2017. Communication towers were taken down, with the county repeater still remaining out of service as of the end of February. The power cooperative that serves the county lost 300 poles and multiple lines affecting 1200 meter-services throughout their coverage area which includes the southern James River Valley of North Dakota. Some secondary feed poles and wires were still in need of repair as of late February 2017.
