- Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
- 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.

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.

- 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).

- 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.

A survey team from the National Weather Service office in Valley concluded that a tornado occurred from about 4 miles west of Uehling to just east of Highway 77 in Uehling. The maximum path width was around 1500 feet. The tornado was rated an EF-1 on the Enhanced Fujita Scale with maximum winds around 90 mph. According to Emergency Management Officials, 10 homes sustained minor damage due to falling tree limbs. Homes and buildings lost a considerable number of shingles. Immediately west of Uehling, there was damage to bleachers and fencing at a ballpark, numerous large tree limbs were blown down, and a few trees were uprooted or snapped at the base of the tree trunk. There were…

A NWS survey team determined a tornado tracked through the eastern and northern sections of Fremont before lifting a little north northeast of town. The tornado touched down near the intersection of old Highway 275 and Morningside Road and progressed north generally east of Lincoln Street. The tornado uprooted or snapped numerous trees, damaged a few homes and severely damaged a garage along its path. One vehicle was flipped over while other vehicles and homes sustained damage from fallen trees. The YMCA sustained major roof damage. A few power poles were snapped near and north of 23rd Street and center pivot was damaged on the north side of town before the tornado lifted. The…

National Weather Service narrative
Rainfall of at least 3 to 5 inches fell over much of the upper Elkhorn River basin in the week ending 7am 6/12, including 1 to 2 inch 24 hour amounts ending 7am the 12th. This caused record or near record flooding along the Elkhorn River from around Clearwater and Neligh downstream to the Elkhorn's confluence with the Platte River. The flooding was prolonged by additional rains the week after 6/12. In Dodge county many gravel roads along the Elkhorn were flooded as was Highway 91 near Nickerson which suffered damage. Highway 275 near Scribner was closed for around week, at first because a temporary dike is used there when the river gets above 18 feet and then because water started…

Several rounds of thunderstorms training over Fremont resulted in flash flooding across the city during the early morning hours of the 21st. The first report of flooding in the city came into the office at 3:47 in the morning. Just before 5 in the morning, fast-flowing water was observed over East 11th Street. Flooded roadways continued to be reported through the morning hours between Fremont and south into Saunders and northwest Douglas Counties.
