- 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.

National Weather Service narrative
The City of North Ridgeville sustained significant and widespread damage from a flash flood on the evening of May 12th. An estimated 300 homes and 1,000 businesses sustained damage from the flood waters. Heavy rain, measured at 6��� in two locations in town, fell within two hours. The intensity and magnitude of the rain has a return frequency of every 500 years. The storm drains were overwhelmed leading to backwater into area basements. The sewage plant on the French Creek sustained $20,000 in damages. The Mill Creek flooded condos on Mill Creek Boulevard resulting in 15 people rescued from the second floor or their homes. The Mill Creek shopping plaza was inundated from…
- Sep 14, 2008High Wind, Lorain$15.0 million
National Weather Service narrative
High winds associated with the remnants of Hurricane Ike began during the early evening hours of September 14th and continued through late evening. A peak wind gust of 71 mph was measured by an automated sensor at the Lorain County Airport near Elyria at 6:04 PM EDT. Damage in the county was extensive with thousands of trees and many utility poles downed. A twelve year old boy riding his bike in Lorain was killed around 6:30 PM EDT. The boy was struck by a falling tree limb and sustained fatal head injuries. In Lorain, a 37 year old female was hospitalized with injuries sustained when her moving vehicle was struck by a falling tree limb. Widespread power outages occurred in the…
- May 21, 2004Flash Flood$12.4 million
National Weather Service narrative
Thunderstorms dumped torrential rains on Lorain County during the early morning hours of May 21st resulting in the worst flooding seen in the county since 1969. The southern portion of the county and especially the Wellington, Oberlin and Lagrange areas were very hard hit. Heavy rain between 2 and 5 a.m. caused the west branch of the Black River and it's tributaries to leave their banks. Rainfall rates were in excess of two inches per hour during the peak of the storm. Just over five inches of rain was measured at the water treatment plant in Lagrange with numerous three inch reports received from both the Wellington and Oberlin areas. Bucket surveys from the area indicate that as…
- Jan 5, 2005Ice Storm, Lorain$4.8 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…
- Dec 22, 2004Winter Storm, Lorain$4.7 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…
- Oct 29, 2012High Wind, Lorain$4.5 million
National Weather Service narrative
Winds in Lorain County gusted to over 60 mph for a few hours. A peak gust of 63 mph was measured by an automated sensor at the Lorain County Airport. Hundreds of trees were downed in the county with most of the damage near the Lake Erie shoreline. Up to 30,000 electric customers lost power. There were reports of trees on houses and vehicles. Many homes also lost sections of roofing and siding. A lot of streets had to be closed because of downed trees and power lines.
- Jun 22, 2006Flood$4.5 million
National Weather Service narrative
Runoff from heavy thunderstorm rains earlier in the night caused streams and rivers in Lorain County to rapidly rise. By mid-morning evacuations were conducted along the East Branch of the Black River in both Lagrange and Carlisle Townships. A total of ten homes were evacuated. In Lagrange Township, four people had to be rescued by boat from their Vermont Road home. Evacuations were conducted later in the morning in Elyria as the Black River flooded the Greenview Drive area. Water rose to the second floors of 13 homes in this neighborhood. At least one person had to be rescued by boat from the roof of his home. The Black River later crested at 16.9 feet, well above the flood stage…
- Jun 23, 2015Flash Flood$4.0 million
National Weather Service narrative
A series of thunderstorms rolled in off Lake Erie during the early morning hours of June 23. Between 5 am and 6 am three separate storms hit northeast Lorain and northwest Cuyahoga Counties with heavy rain and strong winds. The radar estimates rainfall amounts of around 2.5 to 3 inches in a little less than two hours. The rainfall rates spiked to over 5 inches per hour during the height of the storm dropping 2.5 inches in 30 minutes. This intense rainfall overwhelmed storm drainage systems resulting in widespread basement flooding which started before widespread power outages. Some homes on Lake Road had up to five feet of water in their basements. Bay Village received between 2.8…
- Aug 23, 2023Flash Flood$3.0 million
National Weather Service narrative
Widespread flash flooding across northern Lorain County due to heavy rainfall. Widespread basement and isolated first floor flooding reported in Lorain, Elyria, Amherst, Avon Lake, Avon, and North Ridgeville. Widespread flooded roadways reported. Post event damage assessments reported hundreds of homes and businesses flooded. Radar estimated rainfall of 3 to 4 inches falling in a three hour period, which matched several measured rain gauge reports from the area.
- Nov 10, 2002Thunderstorm Wind$2.4 million
National Weather Service narrative
Thunderstorm winds well in excess of 60 mph caused extensive damage in the City of Lorain and Sheffield Lake. A school in Sheffield Lake lost a large section of roof and suffered extensive water damage. 46 homes in the area were damaged by the strong winds, flying debris and fallen trees. Of this total, eight homes were beyond repair and classified as being destroyed. Several homes in Lorain and surrounding areas were also damaged by fallen trees. Hundreds of trees were downed in the county.
