WATCH: Smoke so heavy from Darke County fire, it appears on Doppler 7 Radar

A large structure fire engulfed the swine barn at the Darke County Fairgrounds on Oct. 25, 2018, causing the roof to collapse and causing a smoke plume large enough to be seen on radar.

Storm Center 7 meteorologists were able to isolate Greenville on Doppler 7 and show smoke appearing from the fire registering on the radar. The smoke can be seen going northwest from Greenville.
