Fire
Blanket Creek Fire – Some growth is expected along the eastern and southern
sides over the next couple days.
Spruce Lake Fire –
Minimal fire spread is expected as it finds scattered pockets of fuels. It is in mop up and patrol status.
There are about 10 small fires in the complex. Given the lower humidities, higher winds
and better mixing, fire activity should increase.
Smoke
The winds will continue to be generally from the
northeast in the overnight hours, becoming northwest during the day. This pattern looks to hold through the
weekend. The inversion may lift higher
today, mixing more smoke out of the valleys.
The numerous small fires in the area are leading to a general haze.
Smoke can be expected to move towards the southeast
in the afternoon. In the evening the
smoke will drain down the valleys such as: the Wood River toward Chiloquin
and Klamath Falls and the Upper Rogue towards Prospect and Shady Cove.
Tourists at Crater Lake National Park will be able
to view and smell smoke. Visitors should check for road closures and other
announcements ahead of time. Visitors
