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

  1. Apr 9, 2013Winter Storm, Jackson$15.0 million
    National Weather Service narrative

    An extended period of precipitation began with freezing rain quickly producing heavy ice accumulations, ranging up to a half inch. The precipitation then changed to sleet and then snow, with sleet and snow accumulations reaching 5 to 10 inches. Many branches, limbs, whole trees, and power lines were downed by the weight of ice and accompanying wind. Both urban areas and rural electric cooperatives suffered major power line damage, with the rural cooperatives alone reporting 6 million dollars in damages. Trees and tree debris blocked many roads, and damaged several vehicles and homes. Major power outages were reported, affecting thousands of people. The winter precipitation made…

  2. Apr 10, 2019Ice Storm, Jackson$2.8 million
    National Weather Service narrative

    Ice accumulated to one-half to three quarters of an inch. As winds increased during the night of April 10 into early April 11 with gusts reaching 45 to 50 mph at times, power poles and transmission lines bore the brunt of the worst conditions. Over 1000 power poles were damaged and several hundred miles of transmission lines downed by the weight of the ice accumulation and stress of the high winds. Many roads were closed, including U.S. Highway 71, State Highway 86, and Interstate 90 due to power structures across roadways. Damage costs are rough estimates due to utility costs.

  3. Nov 14, 1996Ice Storm, Jackson$1.5 million
    National Weather Service narrative

    An ice storm consisting of several periods of freezing rain caused widespread damage to power lines and poles, and to trees. Power lines snapped, cable wires were ripped down, and tree debris littered and blocked some roads. Thousands lost power, some for 5 days. Travel was curtailed by icy surfaces and there were numerous accidents, although no serious injuries were reported. The ice storm was described as the worst in 40 years in the Worthington area. Many small farm structures were damaged. A 600 foot radio tower in Worthington was toppled. Schools and business were forced to close. Damage continued after the ice storm ended, including some damage occurring when ice melted…

  4. Jul 1, 2018Flood$750,000
    National Weather Service narrative

    Rainfall of 3 to 5 inches (locally 5 to 10 inches upstream) during the first three days of July exacerbated flooding through the Des Moines River basin. A state of emergency was declared in the City of Windom with water breaching Island Park, the golf course, and several homes. Several county, state and local roadways flooded for up to a week, including highway 62 and numerous city streets. Significant amounts of crop and pasture land near the Des Moines River were severely impacted by major flooding as river levels climbed to the second highest crest on record at 4.4 feet above flood stage at Windom (gage site WDOM5) on July 7.

  5. Aug 7, 2000Tornado$400,000
    National Weather Service narrative

    A tornado damaged several buildings, including businesses and homes, a grain elevator, and trees as it touched down along highway 86 in Lakefield.

  6. Apr 1, 2019Flood$388,000
    National Weather Service narrative

    Runoff from occasional precipitation in late March and April maintained significant flooding of agricultural and pasture lands near the Des Moines River. The Des Moines River at Windom (gage site WDOM5) crested at 1.99 feet above flood stage on April 1. Minor flooding continued at the end of the month.

  7. Jun 21, 2024Flood$355,000
    National Weather Service narrative

    Rainfall amounts across Jackson County from June 20-22 ranged from 4 to 6 inches. Farther north and upstream, 6 to 9 inches of rain fell across portions of southwest Minnesota. This rainfall resulted in widespread overland flooding and major flooding along the West Fork Des Moines River. ||At peak flooding, the city of Heron Lake became surrounded by flood water, resulting in an evacuation notice for 16 homes. Flood water impacted approximately 120 homes in Heron Lake, one of which was declared destroyed. Municipal crews worked 24/7 to keep water from shutting down the sewer system. ||In the city of Jackson, a temporary levee was breached on June 22, allowing flood water from the…

  8. Mar 13, 2019Flood$352,000
    National Weather Service narrative

    All county and township roads were closed to through traffic on March 14. Extensive flood damage was done in many areas. The property damage costs include estimates for public property losses.

  9. Jan 17, 1996Ice Storm, Jackson$200,000
    National Weather Service narrative

    Freezing rain caused severe icing which resulted in damage to trees and power lines. The damage was increased by strong winds which developed as the freezing rain changed to snow. Damage from a building fire near Mountain Lake was aggravated by the inability of firefighters to respond quickly due to the icy roads. Icing of furnace regulators also occurred resulting in furnace shutdowns.

  10. Jul 2, 2000Hail$100,000
    National Weather Service narrative

    Large hail destroyed or damaged 15,000 acres of corn and soybean crops. The hail also broke windows, dented vehicles, and damaged siding.

  1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
