Outlook
Fire season in the Pacific Northwest often lasts from May until October. The National Interagency Coordination Center, in its seasonal fire assessment and outlook released in July, forecast above-normal significant fire potential in the Pacific Northwest through September. The August outlook continued this forecast, predicting that "Significant fire potential will be above average for the entire geographic area in August and September. In October, elevated risk of significant fires will shift west of the Cascades due to the likelihood of dry easterly winds in autumn. By November, significant fire risk will decrease back to normal (i.e., low) for the entire geographic area as cooler and wetter weather arrives."

All Oregon Department of Forestry districts declared the beginning of fire season by July 1. The Northwest Coordination Center upgraded the region's preparedness level (referring to the availability of firefighting resources) from PL 1 to PL 2 on July 3, PL 3 on July 23, PL 4 on August 12, and PL5—the highest level—on August 19.

Impacts
Highway closures and wildfire smoke affected businesses in the vicinity of the Smith River Complex fire, burning in northern California and southern Oregon.
