Severe storms are likely to hit Ohio on Wednesday.
"The conditions are right for a pretty significant severe weather event," said Seth Binau, a meteorologist at the National Weather Service office in Wilmington.
The biggest threat appears to be damaging straight line winds. There is also a chance for an isolated tornado, mainly north of U.S. 30.
"Northwest Ohio into northern Indiana there might be a better threat of tornadoes up there. I do think the bigger threat, however, is the damaging straight line winds," he said.
Binau says the storms could come in waves with a batch in the afternoon and a more organized storm complex moving through in the late evening hours. It's that evening storm system that brings the biggest concerns. Some forecasters say there is a potential for a derecho to form. The storms move quickly and bring very high winds. It was a derecho that knocked out power to more than a million Ohioans last June.
Binau doesn't expect this storm system to evolve like last year's derecho, but that doesn't mean you should let your guard down.
"We shouldn't get caught up in the vernacular of how we term these things," said Binau. "What we should be concentrating on is that there is going to be severe weather and people have to have the plans and the actions in their minds so that when severe weather strikes they know what to do."
Flash flooding is also a big threat from these storms. There is a lot of moisture in the atmosphere and Binau says low lying areas and areas that don't drain well should be on the look out for high water.
The National Weather Service has placed all of Ohio under a slight risk for severe weather and central and western Ohio under a moderate risk.
