  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
  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 city 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.

  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.

  3. Nov 14, 1996Ice Storm, Nobles$2.5 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.

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. Aug 3, 2004Thunderstorm Wind$1.0 million
    National Weather Service narrative

    Thunderstorm winds blew parts of the roofs off a junior high school building and an apartment building, and overturned a semi truck. The winds caused widespread tree damage, including several large trees uprooted or blown down. Tree debris blocked several roads, and made the golf course at the country club unusable. Power lines were blown down and other lines were knocked down by falling tree debris, causing power outages. Tree debris also damaged several vehicles and buildings. At least one garage was destroyed by the winds. Several signs, including large billboards, were blown down. The winds damaged crops, especially corn, but the amount of crop damage could not be determined.

  5. Aug 3, 2004Thunderstorm Wind$1.0 million
    National Weather Service narrative

  6. Apr 10, 2019Ice Storm, Nobles$877,000
    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. Several hundred power poles were snapped by the weight of the ice accumulation and stress of the high winds, with more than 75 miles of power line down. Many roads were closed, including U.S. Highway 59, due to power structures across roadways. Damage costs are rough estimates due to utility costs.
