| Episode Narrative | A Derecho developed over northern Indiana during the early afternoon hours of June 29th. This line of storms intensified as it moved across Central Ohio later in the afternoon. Extensive damage was reported in Hancock, Wyandot, Marion, Morrow and Knox Counties. Lesser amounts of damage were reported just to the north of these counties. The damage from this Derecho is comparable to the damage from the remnants of Hurricane Ike in 2008. Hundreds of thousands of people lost power for as long as a week. Power was not fully restored in Hancock County till July 6th. Thousands of trees and hundreds of utility poles were downed by this line of storms. Hundreds of homes and buildings were damaged by winds estimated to be more than 80 mph. A 84 mph wind gust was measured in Findlay. Automated sensors at area airports failed to record peak gusts because of power outages. Dozens of roads and street had to be closed because of fallen trees and power lines. Significant crop losses are also expected. Clean up costs were significant from this storm. Clean up efforts were hampered by an ongoing heat wave with afternoon temperatures as warm as 100 degrees. |
