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

    National Weather Service narrative

    The continuation of snowmelt from a much above normal snowfall winter combined with a historic heavy snow/blizzard in mid-April resulted in widespread flooding across central and northeast South Dakota. Countless roads along with thousands of acres of cropland were flooded throughout April. Impacts include damaged roads, culverts, and bridges, and livestock, homes, and businesses were affected. Delayed planting resulted across all of the region as well. Cattle and calves were stressed by the cold and wet pattern, as the mud and cold caused some sickness with the livestock. Flooded roads made it difficult for many farmers or ranchers to get to their fields or livestock. There was a…

    National Weather Service narrative

    The snowfall during the season in northeast and central South Dakota exceeded normal levels, with many locations ranking among the top 10 for the snowiest seasons. Additionally, the late spring conditions were unusually cold, resulting in a persistent and exceptionally deep snowpack until early April. The depth of the snowpack ranged from 15 to 30 plus inches, containing approximately 4 to 8 inches of snow water equivalent. However, the weather pattern shifted to abnormally warm conditions in the middle of April. Starting from April 9th, temperatures rapidly rose into the 40s and 50s in areas with deep snowpack, and occasionally reached the 60s and 70s thereafter. The rapid…

    Very heavy rains of 5 to 10 inches caused the Rosehill Dam to break in the early morning hours in southeast Hand county. Flash flooding began around 1 am CDT with two campers being swept up around 130 am CDT. The two campers clung to a tree until they could be rescued around 6 am CDT. They were both injured with one camper being treated for hypothermia and other airlifted to Sioux Falls to be treated for broken ribs and head trauma. ||The dam broke at 330 am CDT with the spillway breaking at 420 am CDT. There was a 100 to 150 foot hole left by the dam break. The flash flooding continued downstream on Sand Creek causing damage to area farms, filling basements, and flooding many roads.
