Updated data indicates insured losses from storms in late June and early July totaled $845 million in Ohio. That's nearly double the Ohio Insurance Institute's initial estimate of at least $433 million. That didn't include $29 million in damage to infrastructure and cleanup costs reported by more than three dozen affected Ohio counties. The institute says the storms between June 29 and July 2 still rank third among the costliest Ohio catastrophes in modern history in terms of insured losses. The Hurricane Ike windstorm in September 2008 tops the list with insured losses of more than $1.2 billion, and the Xenia tornado outbreak in 1974 ranks second. The updated estimate is based on information from Property Claim Services, which collects data about disasters for insurers.
