A majority of the heat and fire activity is located in the area between the Alder Creek fire and the Christensen fire. Fire managers can confirm that the two fires have connected between Turtle Rock and Bryant Creek. The fire will remain most active in the area between the two, and it is expected that they will full connect. Crews continue to implement suppression repair and monitor the large fuels smoldering in the interior of the fire. Resources are also assisting with operations on the Christensen fire.


The team will continue to monitor fire activity on the Sandlake fire and updates will be posted as more information becomes available.


A Red Flag Warning has been issued over the fire area today for high winds, low relative

humidity and warm temperatures. The high-pressure ridge building over the area will flatten out on Sunday allowing for increasing westerly winds with gust in higher terrain potentially up to 25 mph. Conditions will be very dry with poor overnight relative humidity recoveries each day. These conditions will cause the fires to become more activate and fire growth is expected.

traffic with the holiday weekend and hunting season.
