Extreme weather and lousy air conditions delayed a training fire set for Warm Springs Dam this week, reported Cal Fire officials.
Firefighters were due to burn 80 acres of grass on the face of the dam Monday and Wednesday nights — if conditions are favorable, officials said.
But a Spare the Air smog alert issued for Monday and Tuesday put the Monday burn on hold.
Firefighters now are set to burn on Wednesday and next Monday. The fires were expected to run from about 6-9 p.m.
Firefighters from the state and northern Sonoma County were slated to help with the fire at the Lake Sonoma dam.
