- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Waseca County: 6.
- 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.

- 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 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.

- 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 county boundary (or inside the county).
- 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).

Mapped by USGS MN (27).
- 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.

It crossed Elysian Lake near 427th Ave, before moving into southern Le Sueur County. ||Damage was primarily associated with uprooted trees and roof damage. The worst damage occurred to a farmstead which had a metal storage shed collapse along Elysian Lake Road. ||Based on trees uprooted and structural damage to a metal storage shed, winds were estimated around 80 mph.
- Jun 2, 2020Thunderstorm Wind$100,000

- Apr 10, 2019Winter Storm, Waseca$25,000
National Weather Service narrative
Several waves of precipitation occurred across the county with heavy snow at the start, with a mixture of sleet, rain and snow during the overnight hours before transitioning to mainly light snow, drizzle, and freezing drizzle Wednesday, and Thursday. Snowfall totals averaged 6 to 8 inches across the county. ||The other significant weather element was the combination of high winds and ice coated trees and power lines. This led to widespread downed tree limbs, and power poles.
