Richfield

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.

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.

The drought index is for Washington County, the county that contains Richfield.

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. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the city centre.
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 31, 1998Thunderstorm Wind$8.6 million
   National Weather Service narrative

   During the early morning hours of Sunday, May 31st, southcentral and southeast Wisconsin experienced an unprecedented, widespread downburst wind event known as a "derecho." Incredibly powerful, hurricane-force straight-line winds, with peak gusts of 100 to 128 mph tore through 12 counties in this part of the state, while another 8 counties had peak gusts of 60 to 80 mph. Residents noted that the strongest winds only lasted a minute or two, but gusty winds hung on for 15 to 30 minutes. Meteorologically, a solid squall line developed in southern Minnesota and gathered strength as it raced east with a translational speed of 50 to 60 mph across southcentral and southeast Wisconsin.…

2. Jun 8, 2008Flash Flood$5.1 million
   National Weather Service narrative

   Heavy rains resulted in flash flooding over much of Washington County. Water depths on road surfaces reached 3 feet or more and there were gravel washouts. Some farm fields would remain flooded into early July. The breakdown in residential home losses were: 560 affectd with minimal damage, 60 with minor damage, and 12 with major damage (total of about $2.4 million). Business losses were: 45 with minor damage, and 5 with major damage (total of about $1.125 million). Crops losses were estimated at 3.5 million. Public sector damage was about $0.6 million. Several roads and bridges sustained damage.

3. Jun 18, 2006Tornado$4.0 million
   National Weather Service narrative

   This tornado segment is a continuation of the Dodge County segment southeast of Rubicon. This second segment entered Washington County at a location 2.0 miles west of Hartford (about 0.6 mile south of where STH 60 goes east into Dodge Co.) and headed east-southeast through the southern part of the city of Hartford. The tornado strengthened to a high end F1 as it passed through the city. Around 147 residences sustained at least some damage ranging from tree damage to severe structural damage. Ten businesses also sustained structural damage. Lincoln Elementary School's roof was completely destroyed. Estimated damage amounts totaled about 4 million dollars. One person was directly…

4. Jun 1, 2004Flood, Washington$3.0 million
   National Weather Service narrative

   Scattered to widespread heavy rains across south-central and southeast Wisconsin during the period of June 9-12, 2004 kept many rivers and streams at or above flood stage for a good part, or most of the month. Monthly rainfall totals generally ranged from 4 to 7 inches across south-central and southeast Wisconsin, with some scattered spots in Sauk, Columbia, Dodge, Walworth, Racine, and Kenosha Counties picking up 7 to 9.5 inches, or 50 to 100% above normal. In some cases, stretches of some rivers actually went above flood stage in May, 2004. Refer to flood and flash flood events in May, 2004, for additional information. During June, 2004, the high water levels kept much of the…

5. Jun 21, 1997Flash Flood$2.7 million
   National Weather Service narrative

   Flash flooding occurred primarily in southern Washington county as a result of heavy rainfall amounts in excess of 6 inches over a 30 hour period ending about 1200CST. This flash flooding was greater than a "100 year rainfall" based on rainfall frequency maps. No one was injured or killed by the flood waters, thanks to superb rescue efforts by local law enforcement officials and firefighters. Besides public sector damage in county/city parks, there was private and business damages. The hardest hit area was the city of Germantown. There were other reports of flooding damage scattered across the southern part of the county. (On July 7th, Washington county was officially declared a…

6. Aug 10, 2025Flash Flood$2.4 million
   National Weather Service narrative

   Flash flooding of streets, creeks, rivers, and low lying neighborhoods in West Bend and other communities over northern Washington County. Some vehicles were stranded in relatively deep, still water. The neighborhoods near the Silverbrook Creek Parkway experienced the worst of the flash flooding in West Bend, as several homes suffered foundation damage, while most had basement flooding. Some sewer backups occurred in West Bend. Approximately 316 properties reported flood damage.

7. Aug 10, 2025Flash Flood$2.4 million
   National Weather Service narrative

   Flash flooding of streets, creeks, rivers, and low lying neighborhoods in Germantown and surrounding areas. More specifically, the flash flooding of the Menomonee River and its tributaries flooded and closed portions of many roads. This included portions of County Line Road, a lane of I-41, Freistadt Road, Lilac Lane, Maple Road, Rockfield Road, and Wausaukee Road. There was a small number of stranded vehicles in relatively deep, still water, as well as some basement flooding in Germantown.

8. Aug 22, 2013Lightning$2.1 million
   National Weather Service narrative

   A dump truck hauling granite was struck by lightning in the southbound lane of highway 41 north of Sherman Road in the Town of Polk. Some of the granite was propelled from the truck. In addition, a 18 inch deep and 3 foot long hole was found in the roadway from the lightning strike. Two vehicles behind the truck suffered wheel and tire damage due to the asphalt debris lying on the highway. No one was injured.

9. Aug 7, 2012Hail$2.0 million
   National Weather Service narrative

   A trained spotter reported large hail, between 1 1/4 inch and 1 1/2 inch in diameter that fell in Kewaskum. The 5-8 minute hail storm was the worst to hit Kewaskum in many years. Roughly 200 vehicles suffered damage from the hail, as well as many homes, condos, apartments and outdoor equipment. Hail damage to vehicles was about $250,000, and about $1.75 M to buildings and equipment. This information was supplied by local auto-body shops and insurance companies and is a broad estimate.

10. Apr 13, 2006Hail$2.0 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),…
