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

- 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.

- Apr 17, 2013Flash Flood$12.2 million
National Weather Service narrative
Torrential rainfall of 4.00 to 8.00 inches resulted in damage to nearly 2000 houses in the county. Several homes had to be evacuated in the town of London Mills. Every creek and stream in the county was flooded, which damaged a few levees and culverts. Nearly every road in the county was impassable, and numerous water rescues were made. This rainfall lead to record or near record flooding on the Spoon River from April 18th through the 24th.
- Apr 18, 2013Flood$3.6 million
National Weather Service narrative
No homes were damaged by record levels of flooding on the Illinois River. However, thousands of acres of agricultural land and nature reserves were inundated by the flood waters. Several roads along the river were also damaged. The river stage at Havana climbed to a record level of 27.78 feet on April 25th at 19:15 local time, which was nearly 14 feet above flood stage. High impact flooding continued into the month of May 2013.
- Apr 18, 2013Flood$3.0 million
National Weather Service narrative
Record flooding on the Spoon River damaged 40 houses in the towns of London Mills, Bernadotte and Seville. Multiple levees along the river broke, resulting in the inundation of thousands of acres of agricultural land, nature preserves and county roads. A levee at London Mills also broke, resulting on flash flooding in the town during the evening of April 18th through the 19th. ||At Seville, the river crested at a record level of 35.83 feet on April 20th, nearly 14 feet above flood stage, and almost 3 feet above the previous record. The river gage at London Mills became disabled because of the flooding, but manual readings indicated a crest of 26.50 feet on April 19th, the second…

National Weather Service narrative
Dozens of vehicles and numerous homes sustained significant damage from the hailstorm that impacted the city of Canton and surrounding areas.
- Apr 18, 2013Flash Flood$1.5 million
National Weather Service narrative
The levee protecting the town of London Mills from the Spoon River broke in several locations during the evening of April 18th. This exacerbated the flooding which had already occurred the night before from torrential rainfall. Twenty houses were inundated on the south side of London Mills. In addition, Illinois Route 116 and County Road 2 were under several feet of water. Evacuations had been done so there were no injuries reported.
- Jun 29, 1998Tornado$670,000
National Weather Service narrative
A tornado touched down on the west side of Farmington and travelled to the east southeast. It first severely damaged a lumberyard, ripping off the roof of a large storage facility. Then as it moved into the downtown area, several buildings sustained damage to the back walls, as well as, roof damage. Also, several projectiles were found in this area (2x4s driven into the ground). A block down the road a house lost its roof and then as the tornado moved into the east side of town, the second story of a brick building was demolished. Across the street at the high school, a large garage was destroyed which damaged several vehicles. Also, the gymnasium sustained significant roof and…
- May 11, 2002Flash Flood$500,000
National Weather Service narrative
Numerous roads were flooded including Illinois Route 95 near Smithfield. Also, a section of the intersection of Illinois Route 9 and US Route 24 was washed away due to the heavy rains. Some basements were flooded in Farmington. Due to the heavy rains, a car hydroplaned causing it to go into a ditch off Illinois Route 78 near Norris. Four people in the car sustained minor injuries.
- Apr 30, 1997Tornado$450,000
National Weather Service narrative
Two storms merged over Northern Fulton County and within a few minutes a tornado developed a quarter of a mile southwest of Fairview (Fulton County). In Fairview, 6 homes sustained extensive damage and 2 had only minor damage. Two people in Fairview sustained minor cuts and bruises, though no one needed to be taken to the hospital. At this time the tornado was F0 in intensity. After leaving Fairview, it travelled to the northeast. When the tornado reached Middle Grove (Fulton County) it was F1 in intensity and damaged 25 homes. The tornado picked up a 27 foot camper trailer and dropped it upside down 50 feet away on the north side of Route 116. Two mobile homes were destroyed, as…
- Dec 1, 2018Tornado$350,000
National Weather Service narrative
This tornado crossed from Schuyler County into far southern Fulton County about 6.9 miles southeast of Astoria at 3:55 PM CST. The tornado progressed northeastward doing extensive tree damage as it nearly paralleled Highway 100. Additional tree damage and minor roof damage occurred near the intersection of Highway 100 and US-136. The tornado then tracked nearly due northward through rural areas doing tree damage before hitting some homes along North Waterford Road, producing mainly roof and siding damage, along with snapping and uprooting many trees. The hardest hit areas from this tornado were along East County Highway 9 southeast of Lewistown, where more extensive home damage…
- Jun 1, 2010Thunderstorm Wind$225,000
National Weather Service narrative
A corridor of enhanced wind damage occurred along Highway 24 in Fulton County from southwest of Fairview to just south of Farmington. A National Weather Service Storm Survey found several machine sheds, garages, and outbuildings damaged or destroyed along this path. In addition, numerous trees and powerlines were blown down as well. The winds were likely caused by the rear-flank downdraft from a supercell thunderstorm just ahead of the main line of storms.
- 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.
