- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Wyandot County: 0.
- 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.

- 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 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).

- Jan 5, 2005Ice Storm, Wyandot$5.8 million
National Weather Service narrative
For the second time in just over two weeks, a devastating and historic winter storm affected Northern Ohio. Significant ice accumulations occurred over most of the area downing thousands of trees, causing widespread power outages and making travel nearly impossible. Low pressure over Missouri moved rapidly northeast on January 5th. This low moved across eastern Ohio early on January 6th and was responsible for producing a prolonged period of freezing rain. A mixture of rain and snow changed to freezing rain from west to east during the early morning hours of the 5th. Periods of freezing rain then continued for the remainder of the 5th and through the early morning hours of the…
- Sep 14, 2008High Wind, Wyandot$4.0 million
National Weather Service narrative
High winds associated with the remnants of Hurricane Ike began late in the afternoon of September 14th and then continued through much of the evening. Peak wind gusts were estimated to be as much as 70 mph. Damage in the county was extensive with thousands of trees and many utility poles downed. Widespread power outages occurred as well with some customers without power for as much as ten days. Home and building damage across the county was also extensive. The damage ranged from a few shingles torn off to significant structural damage caused by fallen trees landing on roofs. Numerous vehicles were damaged by fallen trees and limbs and also from flying debris. This storm hampered…
- Dec 22, 2004Winter Storm, Wyandot$2.1 million
National Weather Service narrative
A record setting winter storm affected northern Ohio on December 22nd and 23rd. The impact and damage caused by this storm has been compared to the Blizzard of January 1978. Low pressure developed over eastern Texas early on the 22nd and then moved quickly northeast. The low eventually tracked across eastern Ohio during the morning hours of the 23rd after dumping nearly two feet of snow on portions of Ohio. The snow began around daybreak on the 22nd and then intensified around midday. Heavy snow with visibilities of a quarter mile or less then persisted into the early morning hours of the 23rd. Snowfall rates much of this time ranged from one to two inches per hour. Winds…
- Jun 27, 1998Lightning$2.0 million
National Weather Service narrative
A lightning strike ignited a fire that completely destroyed two apartment buildings.
- Jun 29, 2012Thunderstorm Wind$1.3 million
National Weather Service narrative
An intense line of thunderstorms or Derecho moved across Wyandot County during the afternoon of June 29th causing extensive damage. Winds were estimated to be as much as 80 mph. The southwest corner of the county was the hardest hit. Over 50 percent of residents lost power during this event. Power was not completely restored for several days. Hundreds, if not thousands of trees were downed across the county along with many utility poles forcing the closure of dozens of roads and streets. Damage to homes and buildings was also extensive. Dozens of homes and buildings lost roofing or siding with many other homes damaged by fallen trees. Clean up costs were extensive. The clean up…
- May 21, 2004Flash Flood$750,000
National Weather Service narrative
Thunderstorms dumped up to three inches of rain on Wyandot County during the early morning hours of May 21st. This rainfall combined with ground already saturated from heavy rains the previous few days led to widespread flooding. Over a dozen roads in the county were either washed out or flooded. Many homes sustained flood damage.
- Mar 9, 2002High Wind, Wyandot$750,000
National Weather Service narrative
A strong and very fast moving cold front raced east across northern Ohio during the late afternoon and early evening hours. Damaging winds occurred along and behind this front. A 41 year old male was struck and killed by a falling tree in Lorain (Lorain County). A second fatality occurred in Cuyahoga Falls (Summit County) when a 63 year old male was struck and killed by a falling tree. Peak wind gusts include: 69 mph at Toledo Express Airport (Lucas County) at 258 pm; 55 mph at Mansfield Lahm Airport (Richland County) at 415 pm; 63 mph at Findlay Airport (Hancock County) at 423 pm; 62 mph at the Lorain County Airport at 429 pm; 62 mph at Cleveland Hopkins Airport (Cuyahoga County)…
- Jul 13, 2017Flood$650,000
National Weather Service narrative
Heavy rainfall on the morning of July 13th caused the Spring Run to over-top it���s levees around 1045 am. By 11 am State Route 103 and 23 north were shut down. By 1140 am water started to inundate downtown Carey. Major flooding into homes and businesses in Carey occurred around 5 pm when water was at it���s deepest up to 6��� deep. Sixty homes were affected, many from backups of storm drainage. Six to seven homes had water on West Ogg Street mainly from Spring Run. Dozens of businesses directly impacted, mostly with basement flooding. The water receded by 3 am Friday morning. The Tymochee Creek washed out some cross roads near ST RT 103 and RT 106. The waste…
- Aug 1, 2011Hail$500,000
National Weather Service narrative
Thunderstorms produced a swath of large hail across the Upper Sandusky area. Some of the hail was as large as baseballs. Hundreds of vehicles and dozens of homes were damaged by this hail.
- Jan 1, 2005Flood, Wyandot$500,000
National Weather Service narrative
Heavy rain and runoff from snowmelt caused widespread lowland flooding in Crawford, Seneca, Wyandot and Huron Counties the first half of January. January 2005 was among the wettest January's on record with 6.95 inches of rain measured at Bucyrus (Crawford County), 7.65 inches at Galion (Crawford County) and 6.14 inches at Norwalk (Huron County). Temperatures in the 50s the first three days of the month caused a rapid snowmelt and brought area streams and creeks to bankfull just in time for a significant winter storm on the 5th and 6th. Then, just as things began to return to normal, heavy rains fell on the area on the 11th, 12th and 13th causing conditions to once again worsen.…
