INTERACTIVE: Tracking storm events in the Tri-State

Last year's spring and summer storms were costly

The most recent winter storm season has us all looking forward to spring. That could be wishful thinking.

A WCPO analysis of spring and summer storm activity shows at least 150 events reported in Tri-State counties last year, causing an estimated $650,000 in damage.

The “events” – verified weather-related activity that may involve property damage, injuries or deaths – are compiled by the National Weather Service for NOAA (National Oceanic and Atmospheric Administration).

The analysis looks at reports filed between April and October 2013, in Adams, Brown, Butler, Clermont, Hamilton and Warren counties in Ohio; Campbell, Gallatin, Grant and Kenton counties in Kentucky, and Dearborn, Franklin and Ripley counties in Indiana.

About 72 percent of the 2013 events in the Tri-State involved thunderstorms or flooding. Those events were the costliest for residents and businesses – nine of every 10 had reported damage of at least $1,000.

Hamilton County had 35 storm events last year, highest among the counties in the analysis.

Hamilton also had the highest countywide average damage estimate – about $9,900 per event. But Campbell and Kenton counties in Kentucky, and Franklin County, Indiana had damage estimates above the overall Tri-State average of $4,333.

Eighty-six events, all thunderstorm and flood-related, were reported in July. That was the highest total of any month during the period.

The 31 days of July were particularly gloomy in Cincinnati – there was rain or thunderstorm activity on 18 of those days.

Overall, July 6 was the stormiest day during the period, with 27 rain or flood events. Cincinnati, again, felt the brunt of storm activity – measurable rain was reported 17 of the 24 hours that day.
