Twinsburg

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.

Storm Prediction Center severe weather database, 1950 to 2025.

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

National Hurricane Center HURDAT2, 1851 to 2025.

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 Summit County, the county that contains Twinsburg.

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 Summit County, the county that contains Twinsburg.

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 Summit County.

Mapped by NASA (2).

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.

   Thunderstorms dumped very heavy rains on Summit County causing catastrophic flooding in parts of the county. Rainfall rates exceeded two inches per hour at times during the evening hours. Many streams and creeks left their banks causing widespread flooding. Spotters measured 7.20 inches of rain at Richfield and a gage at Hudson High School record 3 inches of rain between 7:45 and 8:15 p.m. with a storm total of 7.5 inches. Five inches of rain was measured in Stow. Two men drown at approximately 8:50 p.m. in an underground parking garage at an condominium complex located along Atterbury Boulevard in Hudson. Witnesses indicated that the underground garage filled with water in just a…

   High winds associated with the remnants of Hurricane Ike began during the early evening hours of September 14th and continued through late evening. Peak wind gusts were estimated to be around 60 mph with the strongest winds occurring between 6 and 8 pm. A peak measured gust of 55 mph was recorded by an automated sensor at the Akron-Canton Airport at 6:53 PM EDT. Damage in the county was extensive with thousands of trees and many utility poles downed. Widespread power outages occurred with some customers without power for several days. Homes and buildings were damaged throughout the county. The damage ranged from a few shingles torn off to significant structural damage caused by…

4. Jul 10, 2013Flash Flood$15.0 million
   National Weather Service narrative

   Torrential rainfall on July 10th ended the streek of 13 days of measurable rain in the Barberton-Norton region, and ending it with the highest rainfall amounts measuring during that time. Almost seven inches of rain fell in the two weeks prior, and on the 10th rainfall amounts in the basin measured between 2 to 3 inches which fell in the hour between 230 and 330 PM. This extreme rainfall rate fell over already saturated ground and swollen stream and creeks, resulting in rapid runoff and flooding. Heavy rainfall of this magnitude overwhelmed the existing stormwater systems with extensive street flooding throughout Barberton. In many areas of Barberton the flooded streets drained…

5. May 12, 2014Flash Flood$11.0 million
   National Weather Service narrative

   Measured rainfall of 4 to 4.5 fell over Cuyahoga Falls on the evening of May 12th between 930 and 1130 pm. Doppler Radar Dual Pol estimated rainfall rates were in excess of 4 per hour around 945 pm. There was significant urban flooding as storm drains were overwhelmed by the excessively high rates. The return frequency for a rainfall event of this magnitude and duration is estimated around a 500 year event. Two adults needed to be rescued from a flooded basement on Dwight Street.

9. Nov 5, 2017Thunderstorm Wind$7.5 million
