<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Monday, October 26, 2009 2:40 PM Jim Little</div>
<div> </div>
<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">The wet Pacific cold front that brought a little rain to the region Monday will be well to the east and dissipating. The cool upper trough supporting that system will move to the northern Rockies leaving a cool northerly flow
aloft over Oregon. This will keep the atmosphere destabilized with mixing heights above 5000 feet most areas. Winds will remain brisk for favorable smoke dispersal conditions most areas. Expect scattered showers during the day, gradually dissipating by late
afternoon. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level ridge builds in the eastern Pacific and moves over the region on Wednesday. Weather will be dry, however the ridge will progress to the east and allow another Pacific warm front to approach the coast Wednesday
evening. This may produce some light rain in the region by Thursday. Friday will see showers with another Pacific front due in on Saturday. Mixing heights should remain fairly high for good smoke dispersal conditions through the outlook period. </div>
<div> </div>
<div> </div>

<div> RANGE PORTION OF ZONE 624</div>
<div> This instruction is valid for burning conducted on Tuesday, October 27, 2009.</div>
<div style="padding-left: 36pt; ">==================================================================</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Avoid ignitions within 10 miles to the NW through N of SSRAs. For units that will smolder significantly through the night avoid burning within at least 10 miles to the NW through NNE in or near drainages leading to SSRAs.
Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. No additional restrictions necessary. </div>
