| Significant Events | Moderate fire behavior with flanking, torching, and short crown runs. Somewhat lower humidity and southwest winds combined with higher temperatures will result in moderate fire behavior. |
Outlook
| Planned Actions | Maintain efforts to hold, improve, and mop-up direct line construction from Poplar Flats to Slate Lake. Continue mop-up along War Creek fire line as fire continues to threaten line through roll outs and updrainage spread. Monitor fire activity along Abernathy Ridge, North Creek, Twisp River, South Creek, and Reynolds Creek drainages. |
| Projected Incident Activity | 12 hours: The Haines Index of 5 Thursday afternoon has led to increased control issues along Abernathy Ridge near Slate Lake. Fire behavior through the evening hours is expected to remain active tonight with areas of burning continuing adjacent to control lines. 24 hours: Somewhat milder temperatures are expected on Friday with gust up to 15 MPH late in the afternoon creating areas of moderate fire behavior at the higher elevations. A Haines Index of 4 is predicted. 48 hours: Saturday will see a slight decrease in temperature and a rise in relative humidity. Expect moderate fire behavior but isolated torching may still occur. A wind shift will occur late Friday in to Saturday. Winds will increase in the afternoon with gusts 15-20 mph. 72 hours: Milder temperature persist with higher relative humidity resulting in continuing moderate fire behavior and slope driven fire spread. Anticipated after 72 hours: The warm weather pattern from the weekend persists along with a gradual increase in fire behavior. |
