Bowman County

Every recorded tornado

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

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

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).

Mapped landslides

Mapped by ND GS (192).

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. Jan 9, 1997Blizzard, Bowman$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…

2. Jan 24, 2010Blizzard, Bowman$1.2 million
   National Weather Service narrative

   Wind gusts to near 50 mph combined with falling snow and existing loose snow cover to create widespread blizzard conditions across Bowman County. The strong winds and blizzard conditions resulted in additional downed power lines and delayed the repair of existing downed power lines. The total estimated damage from this storm (January 18th through January 25th) was over one million dollars.

3. Apr 4, 1997Blizzard, Bowman$750,000
   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…

4. Sep 7, 2009Hail$600,000
   National Weather Service narrative

   A one to two mile wide swath of large and destructive hail was reported. The largest stone was measured at three and one half inches in diameter. There was significant damage to roofs on the north and east sides of Bowman, and to structures in rural north and east Bowman County.

5. Jun 6, 2020Thunderstorm Wind$400,000
   National Weather Service narrative

   Thunderstorm winds blew part of the roof off of the West River Clinic on the southeast side of Bowman. No damage occurred to mobile homes being transported, gas station awnings, campers, or other structures in the area around the clinic. There appeared to be a significant overhang of the roof on that upwind side of the building, where the wind direction and speed caught it just in the right location, to cause the damage. All the debris from the roof blew in a north-northwest direction, with some insulation making it to the Bowman School.

6. Jun 6, 2007Flood$400,000
   National Weather Service narrative

   Total 5.6 inches of rain was reported over the duration of the rain event. Spring creek was running out of its banks. Water was running across farm roads and fields.

7. Apr 19, 2006Blizzard, Bowman$400,000
   National Weather Service narrative

   See StormData entry for Winter Storm for Bowman and Slope counties for April 18 into 19, 2006. The winter storm intensified to a full scale blizzard with zero visibility in snow and blowing snow. Wind speeds were gusting from 35 to 45 mph at the height of the storm. Snow totals had a wide range over short distances. Totals were from 6 inches at Scranton to 22 inches at Bowman and 28 inches at Marmarth. Schools were closed. Power poles were downed under the weight of the heavy wet snow and about 500 people were without power at one time or another. No travel was advised throughout the counties as the storm brought major disruption to tranportation, commerce, and electrical service.…

8. Aug 7, 2007Thunderstorm Wind$300,000

   Farms damaged 9 miles south and 4 miles east of Bowman, 7 south and 3 east of Bowman, and 2 south and 3 east of Bowman. Some damage significant and to grain bins, barns, other outbuildings. and crops.

9. Jan 4, 1997Blizzard, Bowman$250,000
   National Weather Service narrative

   The first blizzard of 1997 hit east-central North Dakota on the morning of the 4th. The blizzard was preceeded by freezing rain that lasted most of the day before switching over to snow. The snow became so heavy that the highway department pulled the plows off of the roads the evening of the 4th and all day on the 5th. It was during the evening of the 4th that the northwest winds began to blow. Winds of 25 to 35 mph were common. Some of the higher snow amounts include 14 inches of snow at Ellendale (Dickey Co) and Linton(Emmons Co), 11 inches at Hague(Emmons Co) and 18 inches of snow at Oakes(Dickey Co). The roof collapsed at the Lull plant in Oakes from the weight of the snow.…

10. Jul 20, 2025Thunderstorm Wind$250,000

    A large pole barn building was severely damaged, with the majority of the roofing material and rafters blown off, one wall completely destroyed, and another wall mostly destroyed. The main leg of a grain distribution system was completely blown over, along with the bin distribution pipes.
