Onida, the town this property stands in, in 102 storm reports between 1993 and 2025: 63 hail, 31 thunderstorm wind, 5 tornado, 3 flash flood.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
A supercell thunderstorm produced an F1 intensity tornado northeast of Onida. The tornado traveled for 5 miles in Sully county and had a path width of up to 600 yards. The tornado caused significant damage to a farmstead 6 miles east and 4 miles north of Onida. The ground in a harvested sunflower field was heavily scoured. Many large hay bales were scattered about. The tornado finally lifted in an open field 10 miles east northeast to Onida.
Winds measured over 110 mph caused a lot of damage in and around Onida. Two small planes were flipped and destroyed at the airport with a hanger also destroyed. Also, a 40 by 40 foot garage was destroyed with many trees downed.
Winds of 90 mph sheared off tens of power poles west of Onida leaving many people without power. The high winds also damaged pole buildings and granaries and overturned several campers at a lake.
A tornado touched down briefly on a farm southeast of Onida. Over half of the roof of a 40 by 45 foot building was torn off and deposited in a tree belt 200 yards to the north. The south wall of this building was caved in and the north wall was pulled out and the overhead door was ripped off. A grain auger was also damaged when it was blown up against a granary. A semi trailer was blown over. About 400 acres of ripe wheat were also flattened and some sunflowers suffered damage as a result of the tornado. Path length and width were estimated.
