Every recorded tornado

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.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

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.

River crests

River gauges in Dane County, the county that contains Oregon.

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

The drought index is for Dane County, the county that contains Oregon.

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

   A strong and destructive tornado spun up at 1715CST about 2.8 miles southeast of the geographic center of Fitchburg (or 2.0 miles north of center of Oregon), about 400 yards southwest of the intersection of CTH MM and Schnieder Rd. It continued east-southeast to the southern edge of Lake Kegonsa and tore through residential neighborhoods about 1/3 to 1/2 mile north of CTH B (Civil Towns of Dunn and Pleasant Springs, and far-northern Stoughton). It moved over the crossing of CTH A with Interstate 90/39, and stayed close to CTH A to its exit point at 1905CST where CTH A crosses into Jefferson County, about 2.8 miles south-southwest of Rockdale. One person was crushed to death in…

   Black Earth Creek crested at 9.73 feet at Black Earth around 2:00 AM on 8/21/18, and at 16.6 feet at Mazomanie around 7:00 AM. The Sugar River and many other creeks and low lying areas continued to flood. The historic flooding resulted in hundreds of citizens rescued, evacuated, or stranded, especially along the highway 14 corridor which parallels Black Earth Creek and then continues into Middleton and Madison. Homes and businesses in Cross Plains, Black Earth, Mazomanie, Middleton, and the west side of Madison were most impacted. Overall, Dane County had 380 homes with affected damage, 857 homes with minor damage, 302 homes with major damage, and 5 homes destroyed. 27 businesses…

   A Tornado severely damaged the Country View Elementary school, which will have to be rebuilt. At least 30 homes sustained major damage, 19 of which were rendered uninhabitable. Many trees down. Estimated winds up to 140 mph.

4. Jun 12, 2008Flash Flood$13.5 million
   National Weather Service narrative

   Heavy rains resulted in flash flooding as water reached depths of 3 feet or more and several cars stalled. This was the last of 6 flash floods in Dane County on 3 different days. The first one occurred on June 7th, the next two on June 8th, and the last three on June 12th. In all six cases, damage to homes, businesses, and crops was noted. It was nearly impossible to break down the damages by flash flood event. Therefore, the collective breakdown is provided in this last June 12th flash flood StormData entry for Dane County.||Some farm fields remained flooded into early July. The breakdown for residential home losses were: 2020 minimally affected, 248 with minor damage, 109 with…

5. Jul 27, 2006Flash Flood$10.0 million
   National Weather Service narrative

   A 1-in-a-100-year flash flood occurred from the west side of Madison to around the Capitol Square after 3 to 5 inches of rain fell within a 90 minute timeframe. There were no reports of injuries or deaths. The heavy rain resulted from slow-moving and back-building thunderstorms that essentially remained nearly stationary over the city of Madison. The hilly terrain and a typical urban setting of a lot of concrete and asphalt enable the runoff water to quickly overwhelm the storm sewers and concentrate water in low-lying areas of the city. Water depths reach to the top of small vehicles - 4 to 5 feet deep in spots. Many roads became impassable due to the flood waters, and many…

7. Aug 18, 2007Flash Flood$6.8 million
   National Weather Service narrative

   Although general flooding affected all of Dane County, significant flash flooding affected the community areas of Mt. Horeb, Oregon, Sun Prairie, and Dane. At least 798 homes in Dane County sustained water damage to basement contents and/or basement walls, with damage totals of about $3.96 million. Thirteen homes had major water damage and two were destroyed, while 783 had minor damage. At least 10 businesses reported minor water damage totaling about $380,000. Crop losses were an estimated $5 million. Livestock losses were about $200,000, and farm building losses were about $500,000. Additionally, road damages were about $538,000, water control facility damage was about $320,000,…

8. Jun 1, 2000Flash Flood$6.0 million
   National Weather Service narrative

   One would be hard pressed to find another day like June 1, 2000 in terms of depth and range of severe, convective weather events across south-central and southeast Wisconsin. Tornadoes, widespread and localized flash flooding, funnel clouds, damaging hurricane-force, straight-line winds associated with a wicked squall-line, large hail stones, urban/small flooding, lightning strikes, and significant mainstem river flooding were reported. As in the preceding weeks, a quasi-stationary front over northern Illinois served as a boundary for warm, moist, unstable air to be pulled north over the cooler air over Wisconsin. Leftover flooding (from the evening of May 31, 2000) and isolated…

9. Apr 13, 2006Hail$5.5 million
   National Weather Service narrative

   Wild weather occurred over parts of south-central and southeast Wisconsin on April 13, 2005. Wisconsin's most-costly hailstorm pummeled a large swath from around Mineral Point (Iowa Co.) to north of Milwaukee (Milwaukee Co.), while hurricane-force thunderstorm winds raked parts of Fond du Lac and Sheboygan Counties. Here's what happened: scattered supercells developed in eastern Iowa during the late afternoon hours of April 13th and pushed east-northeastward through southern Wisconsin and northern Illinois during the evening. Three main hailstorms affected southern Wisconsin. The first hailstorm left a swath of hail and hail damage from southern Iowa County (around 1945CST),…

    Hail size ranged from 1.25 to 3.00 inches in diameter.
