The Diamond Creek and Norse Peak Fires in Washington were very active Tuesday.

The Diamond Creek Fire in northern Washington that has been burning for five weeks spread across the border into Canada Tuesday. A spokesperson for the fire, Connie Mehmal, said it added another 16,000 acres to bring the size up to almost 49,000 acres, but heavy smoke on the north side in Canada prevented accurate mapping. The fire is not being completely suppressed, but special emphasis is directed toward protecting structures, including the community of Mazama on the south side.

Assigned to the fire are 3 helicopters and 3 fire engines for a total of 53 personnel, Ms. Mehmal said.

The Norse Peak Fire on the north side of Highway 410 northeast of Mount Rainier National Park grew by more than 9,000 acres Tuesday and has now burned 12,904 acres. Most of the spread was on the north side, pushed by a strong wind out of the south. The fire behavior on Monday and Tuesday was described as “plume dominated” and “extreme running, group torching, and short-range spotting”.

The strategy on the Norse Peak fire is not to completely suppress it, but to herd it around as necessary to protect private property and structures.

The Chetco Bar Fire in Southwest Oregon has not been growing as quickly in recent days as it did earlier when it quadrupled in size over four days and crossed the 100,000-acre threshold. The most recent mapping puts it at almost 108,000 acres. The area is under a Red Flag Warning on through Tuesday for gusty southwest winds and low humidities which could result in increased burning intensity and rapid fire growth.

The 4,400-acre Jolly Mountain Fire in Central Washington is near a Red Flag Warning area. Fire officials’ expectations for Monday:

Southern and western flanks of the fire will become active with uphill crown runs both on the east and west sides of West Fork drainage. SE flank will continue to back downslope. Fire will become increasingly active as it spreads to the south, where it loses its downslope effect and in more exposed to general winds. Fire likely to cross Sasse Ridge to the west.

The 12,800-acre Liberty Fire has been burning northeast of Missoula, Montana since July 15 while the Rice Ridge Fire, not far away, has spread over 27,800 acres since it started two weeks later. Hot, dry weather on Monday could cause both blazes to become more active.
