Inflamed by ongoing broiling temperatures, the fire danger will flicker up into the extreme range beginning Thursday in Jackson and Josephine counties.

With high temperatures expected to continue into the triple digits through Friday, the Oregon Department of Forestry is increasing the fire danger, which will increase restrictions on outside activity involving the use of chain saws, mowing and cutting dead grass, welding and other potentially fire-starting activities.

New to the list of restrictions this year is the use of tracer rounds and exploding targets. A recent fire on Anderson Butte was started by tracer rounds used in target practice, according to the ODF.

Extreme fire danger in the two counties is not unusual in August. The fire danger was bumped up to the extreme range on Aug. 26 last year.
