- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Foster County: 0.
- 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.

- 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.

- 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.

- 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.

- 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).
- 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).

- 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.

National Weather Service narrative
Damage to 400 farm dwellings and 250 farm structures, including grain bins and farm machinery.
- Jul 21, 2014Thunderstorm Wind$2.0 million
National Weather Service narrative
Severe thunderstorm winds of 65 to 105 miles per hour tore across Foster County causing extensive damage on many farms and in towns. Damage included grain bins destroyed, a grain elevator severely damaged, roofs torn off of outbuildings, and damage to homes. Vehicle damage was also surveyed, including to a semi tractor that was struck by a grain bin. Agricultural damage was severe and extensive.
- Jan 9, 1997Blizzard, Foster$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…
- Aug 6, 2011Flash Flood$1.0 million
National Weather Service narrative
Very heavy rain washed out a culvert under the Canadian Pacific railroad tracks near Kensal at a bridge crossing the James River. The washout caused two locomotives and approximately 25 cars to derail.
- Apr 4, 1997Blizzard, Foster$1.0 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…
- Jan 15, 1997Blizzard, Foster$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…
- Jan 21, 1997Blizzard, Foster$790,000
National Weather Service narrative
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.
- Apr 1, 2009Flood$555,000
National Weather Service narrative
Rapid snowmelt caused heavy overland flooding and flooding along the James River. This resulted in flood damage to numerous county and local roads, railroad bridges, and seven homes.
- Jul 21, 2014Thunderstorm Wind$500,000
National Weather Service narrative
Structural, tree, and crop damage occurred in and around Grace City.
- Dec 26, 2023Ice Storm, Foster$500,000
National Weather Service narrative
Multiple utility poles were broken, along with multiple cross-members. Many miles of power lines throughout the county were down. At one point, 48% of utility customers were without power. Travel became nearly impossible given the icy conditions.
