Outlook
Planned Actions |
Construct direct and indirect line to secure fire perimeter. Construct contingency lines in both zones. Provide structure defense in communities at risk: Paxton, Greenville, Jonesville, Crescent Mills, Taylorsville, Canyondam, Butte Meadows, Bucks Lake, Meadows Valley, Rush Creek and Greater Alamnor area. East Zone: Firing operations will continue in Division W. Continue tactical patrol in the communities impacted by fire. |
Projected Incident Activity |
Fire behavior expected to increase due to drying conditions. Fire continues to move towards controls lines burning unburned interior islands and ridges. Steep terrain, heavy fuel loading, and wind in alignment with canyons is making control difficult near div M and N break. On the East Zone expected area to grow is Division X within the Bucks Wilderness area. Firing operations in Division W will gradually increase total acreage over the next three operational shifts. |

Current Weather
Weather Concerns |
EAST ZONE: Observed: Smoke had continued to clear across even some of the deeper drainage basins across the Dixie East Zone and Evans Fire this afternoon. With the clearing of smoke and clouds temperatures have overachieved and climbed into the upper 80s and 90s. Afternoon humidity values had started to fall into the mid 20 percent range with a few spots seeing humidity in the teens. Afternoon cumulus had bubbled with even some towering cumulus noted south of ICP by the IMET. A few showers and isolated storms had developed along the State HWY 36 and were generally moving toward the northeast. Forecast: Hot conditions with general west winds gusting to around 15 mph. Afternoon humidity may fall down into the teens for a few more sites, but most locations should see RH bottom out near 20 percent. There remains a 20-25% risk for showers and isolated storms across the Dixie East Zone and Evans Fire. Gusty outflow winds along with cloud to ground lightning will be the primary hazards. Activity should diminish after around 2200 LT. Overnight low temperatures are not expected to be quite as low in the valleys and drainages, but it will likely remain mild with temperatures in the upper 50s to near 60 degrees in spots. Overnight humidity values will range as great as 40 percent...even at higher elevations in spots to above 60 percent in the drainage bottoms. WEST ZONE: Decreasing clouds overnight as monsoon moisture pushes east of the region. Evening southwest winds will ease after sunset with nighttime northeast downcanyon winds developing. Return of southwest wind flow on Sunday will keep thunderstorm threat to our east and bring a pretty seasonable weather pattern over the fire. Daytime highs mid 80s higher elevations to mid 90s lower valleys. Less smoke should allow the inversion to lift earlier for the West Zone. Mid and long range trends keep general southwest wind flow across the region with dry and seasonably warm temperatures in place. Observed Weather Conditions: Partly sunny with areas of smoke. Wind Speed/Max. Gust Southwest 8-12 mph gusts 16-22 mph Temp Mid 80s higher elevations with mid and upper 90s lowest drainages. Direction Southwest RH 17-24% Forecasted Weather for Next Operational Period Wind Speed/Max. Gust 14-18 mph Temp Upper 50s lowest drainages to lower 70s ridges Direction Northeast RH 35% ridge and 65% valleys |
