CINCINNATI — A “microburst” with winds of 80 mph to 100 mph knocked over an egg farm barn in which two workers died last week, the National Weather Service said Tuesday.

Two construction workers who were doing masonry work in the barn in Croton, about 25 miles northeast of Columbus, were killed when the barn collapsed on them at the Ohio Fresh Eggs farm.

Andrew Snyder, a meteorologist with the weather service’s Wilmington office, said a microburst is “a very local downdraft” of winds in a thunderstorm.

“When you have rapidly sinking air in a thunderstorm that hits the ground and can’t go down any more, it spreads out very rapidly and produces very strong localized winds,” Snyder said.

The weather service found heavy damage to an area about 100 yards wide and 200 yards long at the facility, while weaker thunderstorm winds downed trees and scattered broken limbs around the area surrounding the farm, he said.

Snyder said damage left by a microburst differs from that of a tornado.

“With tornadic damage you see damage that’s kind of in a swirling wind pattern and that wasn’t the case here,” Snyder said.

Ohio Fresh Eggs and authorities have said the empty barn was one of several undergoing renovation.

The high winds Aug. 4 also toppled two other barns and damaged other structures on the farm.

Authorities have said the two men killed — Kevin Maddox, 25, and Joseph Dixon, 33 — worked for an outside contractor.

Four other people suffered minor injuries.
