CRIDERSVILLE — The National Weather Service has determined that a microburst with 85 to 90 mph straight-line winds is what came through Cridersville Wednesday afternoon. The determination came after weather service officials conducted a damage survey of the area.
A microburst is a convective downdraft with an affected outflow area of less than two and a half miles wide and peak winds lasting less than five minutes. Microbursts may induce dangerous horizontal/vertical wind shears, which can adversely affect aircraft performance and cause property damage. Straight-line winds are generally any wind that is not associated with rotation. They are used mainly to differentiate them from tornado winds.
Wednesday’s storm tore off a portion of the roofs of 30 houses, with 13 homes suffering minor roof damage and broken windows. There were about 30 houses with shingles or siding torn off and about 40 trees had significant damage. The storm also ripped the roofs off of a church and Reichelderfer and Graham Lumber. The storm caused four injuries.
