OHIO — The National Weather Service said Friday that storm damage in Lawrence County on April 2 has been reclassified to have been caused by an EF-1 tornado.

Officials initially thought it was a caused by a "microburst," which is a "a localized column of sinking air (downdraft) within a thunderstorm and is usually less than or equal to 2.5 miles in diameter. Microbursts can cause extensive damage at the surface, and in some instances, can be life-threatening," according to NWS. 

NWS said it made the EF-1 tornado classification after reviewing drone footage, showing that the tractor trailers in Hanging Rock were blown in a counter-clockwise direction in the campground. Additionally, the footage shows several points where convergence was seen in tree damage. 

This brings the total tornado count in Ohio for the year to 28, according to Spectrum News 1 Chief Meteorologist Eric Elwell.

The storms on April 2 spun up nine tornadoes, including the newly classified EF-1 tornado. In addition to that tornado, there were six other EF-1s, one EF-0 and one EF-2.
