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

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.

    National Weather Service narrative

    The tornado began on Bethel Church Road and ended at the Washington County line near where U.S. Highway 51 crosses the county line. Five barns were destroyed directly by wind. Other damage was due mostly to trees falling on buildings. At least four residences were moderately damaged. A machinery storage building and sheds were demolished. An airplane hangar was destroyed.

    National Weather Service narrative

    A house along Beaucoup Creek near the Pinckneyville-Du Quoin Airport flooded. Water in the basement rose to within three inches of the floor joists. Four feet of water filled an adjacent barn. The mortar was washed out of the foundation blocks. The family used a boat to access the house. Numerous basements were flooded around the county, including more than 100 in Du Quoin alone. Sump pumps and shop vacs were sold out at many stores. Several roads were closed in Du Quoin. An intersection was closed by flooding in Du Quoin.

  10. Apr 28, 1996Flash Flood$220,000
    National Weather Service narrative

    Very heavy rainfall of 4 to 7 inches in less than 24 hours caused major flash flooding. Schools were closed in DuQuoin due to flooded roads and school buildings. Sandbags were placed around the Pinckneyville water filtration plant to stave off a rising creek. Perry County was eventually declared a federal disaster area.
