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 storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

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 Wayne County, the county that contains Dearborn.

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 Wayne County, the county that contains Dearborn.

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. Aug 11, 2014Flash Flood$1.1 billion
   National Weather Service narrative

   A historic rainfall event unfolded over Southeast Michigan on Monday, August 11, leading to major flooding and road closures. This event was caused by a strengthening low pressure system moving over the area, focusing the tropical moisture which came up from the south. The hardest hit areas included Metro Detroit and surrounding communities, along with Flint and the Saginaw Valley areas. Wayne, Southern Oakland and Macomb counties saw the worst of the flooding as 4 to 6 inches of rain fell over a 4 hour period. Around 75,000 homes and businesses suffered damage, with over 3000 suffering major damage. There was also damage to the roads and bridges, along with the city sewer pumps…

2. Jun 26, 2021Flash Flood$139 million
   National Weather Service narrative

   Numerous roads and highways became impassable due to flooding. Four to eight inches of rainfall was reported in and around downtown Detroit, with Grosse Pointe Park reporting the highest total of 8.19 inches. Almost 15,000 homes suffered major flood damage, with close to 6000 homes experiencing minor flood damage across the northern part of county.

3. Jul 2, 1997Tornado$90.0 million
4. May 1, 2019Flash Flood$64.0 million
   National Weather Service narrative

   Heavy rain with thunderstorms produced 2 to 4 inches of rain in about a 4 hour window across the I-94 corridor. This amount of rain in a short period caused flash flooding across parts of Wayne County, with the Dearborn Heights area being hardest hit. About 5000 homes experienced basement flooding, with 1000 homes or so suffering major flood damage. Several road closures occurred or were rendered impassable as many cars were stalled out in the high water over the roadways.

5. Mar 8, 2017High Wind, Wayne$25.0 million
   National Weather Service narrative

   A non thunderstorm event took place over the state on Wednesday, March 8, 2017, as high winds brought wind gusts in excess of 60 mph! The high winds took out power lines and trees, along with numerous reports of structural damage to buildings. There were also reports of brush fires and tractor-trailers flipped over around the area. Due to the extensive damage, many areas were without power for several days. Approximately 800,000 DTE customers and approximately 300,000 Consumers Energy customers were affected. The highest wind gust reported across Southeast Michigan was 68 mph at both Saginaw and Detroit Metro Airport.

6. Sep 11, 2000Flash Flood$20.0 million
   National Weather Service narrative

   Widespread, severe urban flooding resulted in a Presidential Disaster Declaration for Wayne County. The communities most severely affected included Allen Park, Dearborn, Dearborn Heights, Ecorse, Lincoln Park, Melvindale, Riverview, Southgate, Taylor, Van Buren Township, Wyandotte, and Wayne. Over 15,000 residences and other structures in Wayne County suffered at least some flood damage. Individual communities tallies included: 2700 homes in Allen Park, at least 500 in Lincoln Park, 2200 in Southgate, and 8000 in Wyandotte. In Allen Park, an estimated 40% of all streets flooded at some point during the event. Underpasses flooded in Dearborn and Dearborn, and street flooding was…

7. Jul 21, 1998Thunderstorm Wind$18.0 million
   National Weather Service narrative

   July 21st was one of the hottest days of the summer in southeast Michigan, as temperatures soared into the middle to upper 90s. An extremely humid airmass was also in place, with dew points in the upper 70s. The above produced an extraordinarily unstable atmosphere, with CAPE values approaching 7000 J/kg. A weak trough of low pressure moved east into western lower Michigan during the afternoon. It was on this trough that thunderstorms first developed. Thanks to the amount of instability present, these storms rapidly became severe. Winds aloft were rather strong for mid-summer, with 40 knot winds less than a mile above ground level (at 850 mb). Thus, the storms were prodigious…

8. Feb 22, 2023Ice Storm, Wayne$16.0 million
   National Weather Service narrative

   A major winter storm impacted Southeast Michigan during the daytime and evening hours of February 22, 2023. Warm/moist air originating in the Gulf of Mexico surged north toward a surface warm front, increasing coverage and intensity of precipitation over lower Michigan by mid-morning. This warmer air aloft interacted with a resident cold airmass near the surface, creating conditions favorable for snow to the north and a wintry mix for much of the metro Detroit region. The higher snow accumulations occurred across areas well north of I-69, with Midland, Bay, Tuscola, and Huron counties reporting 5 to 9 inches. Communities along and south of I-69 saw a wintry mix of snow, sleet, and…
