Smoke
Warm and dry weather conditions continue today. The south section of the August Complex fire will see an early movement of smoke to the east and southeast driven primarily by terrain factors (i.e., slope and valley influences). Later in the day, with a more southwesterly wind, smoke should extend to the east-northeast, then shift back to a more terrain-influenced direction (south–southeast) in the late afternoon and into the evening. The north section of the fire will be influenced by southwesterly winds carrying smoke to the northeast throughout the day. In both sections, smoke should lift by late morning, then begin to settle toward late afternoon–early evening. Expect smoke to affect communities northeast, east, and southeast of the fire for most of the day.
