  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Saline County: 8.
  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. Mar 18, 2008Flood$16.8 million
    National Weather Service narrative

    Over 16 million dollars in damage occurred to homes and businesses in Harrisburg due to disastrous flooding. Five homes and one business were considered destroyed. At least 30 homes and 44 businesses had water over the first floor. All three of the supermarkets in the city were closed due to flooding. Eighteen homes and three businesses reported water in the basement, though many others likely did not report basement flooding. About 300 residents of the city were evacuated, many to a Red Cross shelter. Emergency personnel evacuated at least one family from flooded areas outside the city. Many streets were closed in Harrisburg. U.S. Highway 45 was closed for days. Significant…

  2. May 8, 2009Thunderstorm Wind$4.5 million
    National Weather Service narrative

    Widespread wind damage occurred across the county. The pockets of greatest damage were in northern parts of the county including Galatia and Raleigh, as well as southwestern parts around Carrier Mills. Harrisburg itself escaped the worst of the damage, and power outages there only affected several hundred customers. Winds were estimated near 90 mph in the Harco area. Extensive power outages lasted three to six days in the hardest hit areas, including Galatia. The power losses rendered pumping stations that supply water inoperable. Many structures were damaged. Every street in Galatia had trees down across streets, houses, vehicles, or outbuildings. Two homes in Galatia received…

  3. Apr 28, 2002Tornado$3.5 million
    National Weather Service narrative

    The tornado struck Galatia directly, damaging about 55 structures and destroying several. Peak winds were estimated between 120 and 130 MPH. The roof of a car wash was blown off, and then the walls collapsed on a police cruiser that was sheltered there. A coal mine sustained a quarter million dollars in damage. Two persons were injured in an overturned trailer. Two brick homes lost their roofs and some walls.

  4. Feb 29, 2012Tornado$2.0 million
    National Weather Service narrative

    The tornado touched down about a mile north of Carrier Mills, then moved east-northeast through Harrisburg. The violent tornado produced a swath of devastation in south and southeast parts of Harrisburg. In Harrisburg, over 200 homes and about 25 businesses were heavily damaged or destroyed. The damage was in residential neighborhoods in the far south and southeast sections of Harrisburg. The commercial strip along U.S. Highway 45 in the south part of the city was directly impacted. A strip mall on the east side of U.S. Route 45 was destroyed. The tornado struck the Harrisburg medical center and surrounding residences on the southeast side of town. At least ten homes or other…

  5. Apr 28, 1996Flash Flood$1.5 million
    National Weather Service narrative

    Widespread rainfall amounts from 4 to 7 inches in 24 hours caused extensive flooding. A pickup truck stalled in high water in rural Saline County. By the time the owner returned to it, it was submerged under 6 feet of water. Extensive flooding of farm fields forced farmers to delay spring planting indefinitely. The Harrisburg water treatment plant reported 5.75 inches in 24 hours. A number of roads and highways were closed. Schools were closed. Saline County was declared a federal disaster area. About 1.3 million dollars damage occurred to private property.

  6. May 10, 1996Flash Flood$1.5 million
    National Weather Service narrative

    Many roads became impassable. One bridge was moved about a foot. The flooding from this event combined with the late April flooding caused very heavy damage. Saline County was declared a federal disaster area. Rainfall totals from late April into early May were near a foot in many areas. The damage total is for the series of floods.

  7. May 8, 2024Flash Flood$800,000
    National Weather Service narrative

    Significant flash flooding occurred in Eldorado. Ferrell Hospital sustained floodwater damage with 55,000 sq ft of the hospital affected, requiring transfer of patients to other facilities. Flooding on roads leading to the hospital hindered emergency crews. Several streets around the city flooded, and water intruded into the Eldorado High School entrance. Torrential rainfall rates produced radar estimated 1.5-2 inches of rain in Eldorado, with most of the rain occurring between 1515-1615CST. Flash flooding transitioned to a flood event through the evening.

  8. Apr 3, 2018Tornado$500,000
    National Weather Service narrative

    The tornado entered Saline County from Williamson County. In Saline County, three homes were destroyed. The peak intensity occurred between the Williamson County line and Galatia, where a single-wide mobile home was completely demolished. A well-built house was completely unroofed, and portions of the exterior walls collapsed. Peak winds were estimated near 125 mph at this location. Over a dozen other homes were damaged, with at least partial loss of shingles and siding. A couple dozen barns and pole barns were destroyed or heavily damaged. Hundreds of trees were snapped or uprooted.

  9. Sep 14, 2008High Wind, Saline$500,000
    National Weather Service narrative

    Frequent wind gusts from 60 to nearly 70 mph caused considerable damage in southern Illinois. The low pressure center that was the remnant of Hurricane Ike raced northeast at 40 to 50 mph across Missouri and Illinois. The center passed between Carbondale and St. Louis on its way toward the northeastern states. The rapid speed of the low pressure system contributed to this high wind event.||Considerable tree damage occurred. Trees were uprooted, and very large limbs were broken. Some trees fell on homes, outbuildings, and vehicles. Fewer than a dozen homes in each county were damaged by falling trees. Others fell on commercial and public buildings. Numerous trees or limbs fell on…

  10. Feb 11, 2008Winter Storm, Saline$500,000
    National Weather Service narrative

    Low pressure developed over the southern Plains, spreading widespread heavy precipitation across southern Illinois. At the same time, high pressure over the upper Ohio Valley produced a cold easterly wind flow. The result was a crippling ice storm. Around one inch of ice caused extensive damage across far southern Illinois, along and south of a line from Carbondale and Marion to Harrisburg and Carmi. Many of those same areas received three to six inches of sleet and snow. The most destructive icing occurred in an east to west band across Union, Johnson, Massac, and Pope Counties. The state designated most counties in southern Illinois as a disaster area. Numerous trees and power…
