Outlook

Planned Actions Chiwaukum Creek: continue to hold fire west of highway; and continue to identify and implement containment options in the northern and southeastern areas of the fire. Continue to provide structure protection where needed.

Kelly fire: Resources will be inserted into the fire and continue implementing direct line construction.

Duncan: Continue to develop indirect containment lines and shaded fuel breaks along roads and dozers lines.

Projected Incident Activity 12 Hours:

Fire spread during the overnight hours is expected to minimal with no perimeter growth. Heavy fuels will continue to consume in the interior, with creeping and smoldering fire behavior.

24 Hours:

Creeping and smoldering fire behavior is expected. No perimeter growth expected.

48 Hours:

Creeping and smoldering fire behavior. Some minor perimeter growth should be anticipated.

72 Hours:

Minor perimeter growth is expected. Continued consumption of interior fuels and smoldering and creeping fire behavior.

After 72 Hours:

Hot and dry conditions are expected, leading to more active fire behavior including torching, spotting.

Remarks Personnel will continue to support local initial attack as needed. National Guard troops (100) are active and engaged in fire management activities in the eastern edge of the fire area. More favorable weather has allowed resources to return to the fire area and resume implementation of fire suppression activities in most fire areas.

Current Weather

Weather Concerns The wet weather pattern has exited the fire area. Total precipitation at Hatchery ICP was 0.41″.

The primary weather concern continues to be the moderate northwesterly winds expected across the area; 15 to 25 mph with gusts to 35 mph. A significant warming and drying trend will begin Friday and continue through the upcoming weekend as high pressure builds over the Pacific Northwest. Temperatures will rebound quickly, reaching upper 80s to low 90s by Saturday, while relative humidity is expected to be in the low 20s. Hot and dry conditions are expected to persist through early next week. The potential for triple-digit valley temperatures returns by the middle of next week.
