Henry County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Henry County: 5.
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

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.

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 county boundary (or inside the county).
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).

   National Weather Service narrative

   NWS storm survey showed a tornado touched down 3 miles south of New Bavaria and traveled close to 4 miles lifting 3 and one half miles east southeast of New Bavaria.

3. Oct 30, 1996High Wind, Henry$75,000
   National Weather Service narrative

   A deep low pressure moving east across Ontario Canada brought winds of 60 to 70 miles per hour, with higher gusts, to Northern Ohio. Trees, limbs and power lines were downed, some across roads, and others on cars, and buildings causing considerable damage. In Cuyahoga County, at Cleveland Hopkins Airport, a stewardess was blown off the steps of a commuter plane but was not injured. At least 2 cars, a truck and a house were struck by falling trees in Bay Village and shingles were blown from roofs in Berea. In Wayne County, signs were ripped from their standards and dropped on roads and a landfill was closed in Paint Township because of flying metal and tin. At Apple Creek, the arc…

   National Weather Service narrative

   Emergency management officials reported three areas of water covered roadway on US 24 and Ohio 424 along the Maumee River. Closure of a bridge crossing over Turkey Foot Creek, southeast of Napoleon prompted the closure of County Road P.

5. Jan 12, 2005Dense Fog, Henry$50,000
   National Weather Service narrative

   Widespread dense fog developed across much of northwestern Ohio during the morning hours. Visibility was reported to be at or near zero in many locations. Numerous accidents were reported with at least 1 fatality and 1 injury indirectly resulting from the dense fog. A 38 year old man was killed near the intersection of Ohio 18 and 281 in Defiance county. A chain reaction crash occurred when a semi struck a vehicle on the side of the road, causing additional vehicles behind the semi to crash as well. The unusually dense fog was the result of very warm and moist air moving over a rapidly diminshing snowpack.

6. Aug 3, 2022Thunderstorm Wind$40,000
   National Weather Service narrative

   A trained spotter reported that several large trees and limbs were down near the intersection of Road 11 and Road S. A large tree was downed and damaged the roof of a barn.

7. Mar 13, 1997Ice Storm, Henry$40,000
   National Weather Service narrative

   Freezing rain with temperatures around 32 degrees fahrenheit caused 1/4 to 1/2 inch of ice to form on colder surfaces such as trees and power lines which were downed by the added weight. This resulted in numerous power outages. Some basements filled with water because of the lack of power to run electrical sump pumps. Many trees and branches were downed on cars. Scores of traffic accidents occurred as roadways were transformed into hockey rinks. Throughout the day on the 14th, patchy freezing rain continued, accompanied by gusty winds, resulting in a few more downed trees.

9. Jun 1, 1997Flash Flood$30,000
   National Weather Service narrative

   Heavy thunderstorm rain that began in May continued to fall on saturated ground, causing flooding of streets, streams, homes, fields and low lying areas. Many roads were closed and berms washed out forcing the closing of some schools. In Bay Township (Ottawa County), Muddy Creek overflowed its banks and flooded a trailer park. Firemen dropped their hoses into the floodwater and used it to extinguish the blaze when one of the trailers caught on fire. In Bettsville (Seneca), the local fire department sandbagged several houses to keep the waters of Wolf Creek from flooding the homes. In Twinsburg (Portage), several homes,roads and low lying areas were flooded by Tinker's Creek, which…

10. Feb 24, 2007Ice Storm, Henry$30,000
    National Weather Service narrative

    Two to four tenths of an inch of ice covered roads and power lines, creating hazardous driving conditions, widespread power outages and damage to trees. No injuries or deaths were reported in the county.

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.
