PROSSER, Wash-- Smoke continues to fill the air in Prosser after 1,500 tons of hay burn over the weekend.
The fire started around 3:00 Saturday morning at North River Road and Wilgus Road.
Firefighters have now turned the investigation over to the Benton County Clean Air Authority after determining it's no longer a fire danger.
Clean Air representatives believe it was started accidentally but don't have any details on how.
Meanwhile they hope some wind will help get rid of the smoke.
