  • Drought09/01/1999

    Morrow

    $5M damage

    What happened

    Drought conditions continued across most of northern Ohio during September. Widespread heavy rain occurred on the 29th but did little to help crop conditions. For the month, only 1.63 inches of rain fell in Mansfield making it the 9th driest September on record. Of the 1.63 inches, 1.14 inches fell on the 29th. Even with an inch of rain on the 29th, both Toledo and Cleveland finished with below two inches of rain for the month. Losses from reduced crop yields are estimated at $200 million for northern Ohio alone.

  • Ice Storm01/05/2005

    Morrow

    $4.8M damage

    What happened

    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 6th. Temperatures eventually warmed enough during the late morning hours of the 6th to change the freezing rain back to rain. The hardest hit locations were west of Interstate 71 along the U.S. Route 30 corridor. Ice accumulations of greater than three quarters of an inch were reported from Hancock County eastward across Wyandot, Crawford, Richland and Ashland Counties. Northern sections of Wyandot and Marion Counties along with the southern halves of Seneca and Huron County were also hard hit....

  • Winter Storm12/22/2004

    Morrow

    $3.8M damage

    What happened

    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 increased significantly during the evening hours of the 22nd as northerly winds developed on the backside of the low. Gusts to 30 mph caused significant blowing and drifting and near blizzard conditions from Marion County northeastward into Erie and Huron Counties. Drifts several feet deep were reported. Temperatures warmed slightly during the early morning hours of the 23rd as the low moved into southeast Ohio. This caused the snow to first mix with, and then change completely to freezing rain....

  • High Wind61 kt wind09/14/2008

    Morrow

    $3.3M damage

    What happened

    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. Wind gusts were estimated to be nearly 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 travel as downed trees and power lines forced the closure of many roads. Substantial clean up costs were incurred by local governments. Many of the schools in the county were forced to close on Monday the 15th because of the power outages. Significant crop losses occurred as well. Corn yields were reduced between 3 and 5 percent in many areas with lesser losses to the soybean crop.

  • Winter Storm01/02/1999

    Morrow

    2 injured, $15K damage

    What happened

    Snow changed to freezing rain and sleet, with a brief change to rain as temperatures rose slightly above freezing, and then back to snow. Temperatures dropped quickly into the teens causing the wet snow and ice to refreeze and creating significant ice on the ground, roads and sidewalks. Snow accumulations generally averaged six to eight inches with as much as 10 inches in northwest Ohio. Travel was restricted when some counties declared level two or three emergencies, including Wood, Lucas, Seneca and Hancock. Air temperatures eventually fell to near zero and the icy conditions and cold temperatures, with wind chills of around 30 degrees below zero, continued throughout the first week of January, closing schools and causing many minor car crashes and fender benders. Dozens of people were injured from falls on the ice. Many sidewalks and secondary streets remained uncleared for days due to the combination of very cold temperatures and thick ice. Salt was in such demand that most stores ran out and had difficulty restocking.

  • Thunderstorm Wind70 kt wind06/29/2012

    Climax, Morrow County

    $2M damage

    What happened

    An intense line of thunderstorms or Derecho moved across Marion County during the afternoon of June 29th causing extensive damage. Winds were estimated to be as much as 80 mph. Over 75 percent of residents lost power during this event. Power was not completely restored for almost a week. 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. Hundreds of homes and buildings lost roofing or siding with many other homes damaged by fallen trees. Clean up costs were extensive. The clean up was hampered by an ongoing heat wave with afternoon temperatures in the upper 90s. Significant crop losses are also expected. Damage from this storm was comparable to the remnants of Hurricane Ike in September 2008. Damage to public property alone was over $700 thousand.
