  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.

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.

  2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

  1. May 27, 2019Tornado$15.0 million
    National Weather Service narrative

    The tornado appeared to have first touched down west of Celina, near the intersection of Township Line Road and Bunker Hill Road, where about half of a barn's metal roof was removed and strewn in a narrow path to the east-northeast. At least two other barns also lost nearly half of their metal roofing in the vicinity of Bunker Hill Road. Numerous trees in this area, with trunk diameters of 18 to 24 inches, were also snapped and blown down in various directions. This type of damage was consistent with wind speeds of up to 90 mph and associated with an EF1 tornado. ||The next damage occurred to homes and adjacent outbuildings along Mud Pike Road, immediately southeast of the…

  2. Nov 5, 2017Tornado$11.0 million
    National Weather Service narrative

    This tornado developed in Delaware County, Indiana, near the town of Eaton and then moved across Blackford and Jay Counties in Indiana before crossing into Mercer County, Ohio at 1418EST near the intersection of St. Anthony Road and County Road 235 (see Storm data for Indiana, Central and Northeast, for more information on the beginning portion of this tornado in Indiana). The tornado traveled northeast in Mercer County for just more than 8 miles before terminating in a wooded area north of Carmel Church Road and west of Now Road. A few pieces of light debris were carried slightly further to the northeast, but the tornado is not believed to have been on the ground east of Now…

  3. Nov 5, 2017Tornado$5.0 million
    National Weather Service narrative

    Law enforcement initially observed a funnel cloud near the intersection of Main Street and Schunk Road in Celina. Just to the northeast of this report is where it appears the tornado first touched down, where multiple tree limbs were knocked down between Main Street and W Bank Road.||It is believed that the tornado then skirted Grand Lake St. Marys, producing minor tree and structural damage near the corner of Lake Shore Drive and Elmgrove Avenue. The tornado then likely moved back over a small portion of Grand Lake St. Marys before knocking down a fence and a few small trees at the back parking lot of a Wendy's restaurant on E Market Street. A one story home on Vine Street also…

  4. Sep 14, 2008High Wind, Mercer$4.9 million
    National Weather Service narrative

    Strong winds of 40 to 50 miles per hour were sustained for several hours. Gusts over 60 mph were common. Widespread damage occurred across the region, from trees being blown down on powerlines, to significant crop losses and structural damage.
