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.

River crests

River gauges in Madison County, the county that contains Norfolk.

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 Madison County, the county that contains Norfolk.

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.

Every earthquake of magnitude 4 or more within 50 miles

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).

Mapped landslides

Landslides mapped in Madison County.

Mapped by NE Univ of NE Lincoln (1).

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.

1. Dec 30, 2006Winter Storm, Madison$1.5 million
   National Weather Service narrative

   Freezing rain accumulated from at least 1/2 inch to over 1 inch in some locations on trees, power lines, vehicles and other untreated objects. The weight of the ice, and a mix of light sleet that also fell briefly late Saturday night, caused widespread tree damage and also felled numerous power lines and power poles. The area most hard hit was from north through west through southwest of Norfolk where some 500 power poles were toppled and power was lost for days. Fallen trees also caused damage to cars and houses...mainly to western Madison county. The storm caused around 1.5 million dollars worth of damage to utility companies in the county.

2. Jun 14, 2010Flood$1.0 million
   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. 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 and intensified by additional rains the next few days. In Madison county many gravel roads along the Elkhorn were flooded as were Highways 81 and 275 near and west of Norfolk which were closed for a while. On 6/15 a railroad bridge just southwest of Norfolk washed away with 3 people on it that were assessing possible damage. One person was drowned, the 2 others were rescued. Another…

3. Jun 18, 1998Flood, Madison$500,000
   National Weather Service narrative

   Flooding along the Shell Creek caused significant damage to homes and businesses in the Newman Grove area.

4. May 30, 2007Flood$500,000
   National Weather Service narrative

   Rainfall of 2 to 4 inches fell across much of Madison county. The heavy rain caused Battle Creek to flood low areas around the Battle Creek area, including Highway 121 near town causing its closure. The creek also flooded the water treatment plant and prompted sandbagging around town, with up to 10,000 bags used. At least 400 homes received some sort of flood damage. The flooding also left debris in several county bridges.

5. Jun 4, 1999Flash Flood$300,000
   National Weather Service narrative

   Around 5 inches of rain fell in the Madison area causing flash flooding along Union Creek which forced some residents along the creek to be evacuated to the auditorium. The heavy rain also ripped up around a block of asphalt covering a brick street and washed out a half-mile section of railroad track near town.

6. Apr 14, 2012Flash Flood$200,000
   National Weather Service narrative

   Rainfall, unofficially up to 5 inches in parts of Norfolk, combined with large accumulations of hail and caused flash flooding in parts of Norfolk and other locations across the northern sections of the county. In Norfolk the hail and heavy rain clogged storm drainage systems flooding streets and causing flooded basements. In addition, the hail clogged the drainage system for stairway that led down to the emergency room of a local hospital. The entrance then filled with water which caused the steel door to collapse sending a flood of water into the hospital. This caused the relocation of the emergency entrance and also prompted the moving of some patients.

7. Mar 13, 2019Flood$194,000
   National Weather Service narrative

   This is for flooding along the Elkhorn River. The river gage at Norfolk, operated by the USGS, peaked at 15.5 feet at 7 am on March 14th. Minor flood stage is 12 feet. Major flood stage is 17 feet. Preliminary this was the 3rd highest crest on record. A 30 year old man was killed by flood waters when he was on top of a car at 4 am CDT on the 14th in a field east of north First Street in Norfolk. Water swept away the man and the body was never found. Water closed US Hyway 275 on the 14th and numerous streets were under water due to the flooding in Norfolk.

8. May 27, 2012Thunderstorm Wind$150,000
   National Weather Service narrative

   Thunderstorm wind gusts estimated at over 60 mph destroyed a silo and part of a cattle barn on one farmstead about 8 miles west of Madison and a center pivot system was overturned in that area. A machine shed sustained heavy damage around 9 miles west of Madison.

9. Jun 15, 2024Flash Flood$100,000
   National Weather Service narrative

   Public report of county roads submerged in water. A storm damage survey the next day confirmed several locations where the roads were still under water or partially washed out. By around 7 PM CDT, widespread street flooding was reported in Norfolk. As the storms slowly moved southeast, additional flooding was reported by a county official across central portions of the county where numerous county roads were flooded in addition to considerable lowland flooding.

10. Sep 30, 2007Lightning$100,000
    National Weather Service narrative

    A lightning strike started a house fire in Norfolk causing around $100,000 damage.

1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
