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 Hennepin County, the county that contains Maple Grove.

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 Hennepin County, the county that contains Maple Grove.

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.

Mapped landslides

Landslides mapped in Hennepin County.

Mapped by USGS MN (474), NASA (3).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

   National Weather Service narrative

   A large storm swept across most of northern Hennepin County, accompanied by large hail and a brief tornado. An NWS damage survey, spotter reports, video, and radar imagery indicate the storm had a very strong rear flank downdraft which was reported to have been sustained as long as 10 minutes in some locations. The wind and hail were responsible for virtually all damage (see separate reports for the hail), and a tornado was on the ground only briefly in Brooklyn Park (see separate tornado entry for Hennepin County). Tens of thousands of trees were downed, including some snapped a few feet off the ground. Many roads were blocked. Some neighborhoods were without power for more than…

It gained F2 status briefly as it moved through a residential neighborhood in Rogers, where it took the life of a 10 year old girl in a home. A home weather station 2/3 mile southeast of the tornado at this point measured 65 mph inflow winds. The tornado crossed Interstate 94 and entered another neighborhood, where F1 damage was produced. One house with significant damage had a home weather station in the back yard. Once the data were retrieved, its peak…
