  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Orange County: 0.
  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.

  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.

  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).

Around 70 homes and a few businesses received major damage in Washington, Crawford and Orange counties. Two mobile homes were destroyed in Orange county. Evacuations were made in Milltown, Henryville, English, Paoli and Fredericksburg. The Blue River crested at 27.1 feet at Fredericksburg (20.0 flood stage) at 1800 est on April 29. It crested at 28.9 feet (16.0 flood stage) at Milltown at 0500 est on April 30.

  4. Dec 22, 2004Heavy Snow, Orange$200,000
    National Weather Service narrative

    A winter storm brought heavy snow to south central Indiana. Storm total amounts of 20 to 30 inches were reported over the area. High winds developed later in the day on the 23rd, creating drifts of snow up to four or five feet. Most roadways were dangerous or impassable, and sections of Interstate 64 were closed for a time due to accidents. The roofs on several business warehouses and storage buildings collapsed due to the weight of the snow in Jasper (Dubois County) and Paoli (Orange County). At least 11 turkey houses in Dubois County collapsed due to the snow. Hundreds of birds were killed or injured (this agricultural loss is reflected in the crop damage figure quoted above).…

  5. May 25, 2011Tornado$150,000
    National Weather Service narrative

    This tornado touched down along Highway 37 south of Orleans, uprooting and snapping several trees. It expanded to its maximum width and strength one mile into its path, where it heavily damaged two brick homes and one wooden frame home, as well downing power lines and poles. In this area it also did extensive damage to several outbuildings, completely destroying one barn and overturning a tractor within. The tornado continued to the northeast, damaging another outbuilding a mile to the northeast and uprooting and snapping numerous trees before finally lifting in an open field 3/4 mile southwest of the community of Leipsic.

  6. Nov 14, 2011Tornado$100,000
    National Weather Service narrative

    A tornado first touched down on the north side of the Paoli school complex three quarters of a mile west of the downtown square. It destroyed a 100 year old barn and heavily damaged the roofs of two other outbuildings. It then removed a large section of roofing from the Paoli police department on West Main Street before snapping several trees along Lick Creek. Based on a damage survey, this tornado was classified as an EF-1 with peak winds from 95 to 100 mph between its initial touchdown and the Paoli town square. While moving across the town square, this tornado ripped the metal roofs off of two businesses. Three chimneys on the Orange County Courthouse collapsed. Moving east of…

  8. Mar 1, 2017Thunderstorm Wind$75,000
    National Weather Service narrative

    A NWS Storm Survey team found that thunderstorm winds destroyed an outbuilding approximately 1/2 mile northwest of Leipsic. The damaging winds continued into the community, scattering debris from the outbuilding and damaging several homes in town. The winds winds tore part of the roof off one home, fanning debris to the east. The estimated time of the event was 1 minute.

  9. Mar 1, 2017Tornado$75,000
    National Weather Service narrative

    This is an extension of the Lawrence County EF-2 tornado that briefly crossed into Orange County before lifting. The tornado produced EF-1 level damage in Orange County, destroying two mobile homes. One mobile home rolled over onto a new vehicle where three occupants were unhurt. The car ended up inside the living room of the mobile home. The other mobile home took a direct hit, taking the roof off and blowing the walls out of half of the home. An occupant of the home was blown into the field with home debris, while leaving living room furniture in place. The resident received only minor injuries.
