Firefighters are continuing to work on five lightning-caused fires on and near the Fremont-Winema National Forest in Southwest Oregon.

The first four fires were less than five acres combined, the U.S. Forest said in a news release. The fifth, the Dairy Fire, was discovered Saturday about one mile east of the Gearhart Wilderness. There are no evacuations and the campgrounds are not at risk.

The Dairy Fire is in an area where prescribed fires were planned for the fall. Conditions in the area – temperature, humidity, fuel moisture, winds and smoke – are consistent with those for prescribed burns, so firefighters are allowing the fire to expand to treat the area. They expect the maximum size of the fire will be 110 acres.
