<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div> ** Stable Pattern – Poor Smoke Dispersal Conditions Continue **</div>
<div> </div>
<div style="padding-left: 36pt; ">A weak pacific weather system moving through British Columbian and northwest Washington Monday and Monday evening will be well to the east of the area tomorrow. This will allow the upper level ridge to strengthen for very
stable conditions over the region. Expect fair weather but low mixing heights, mostly south to southeasterly winds, and generally poor smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Wednesday is a transition day as the upper ridge axis shifts eastward. Expect some improvement in smoke dispersal conditions. Winds will be generally light southerly. By Thursday an upper trough will be approaching as the
upper ridge axis moves out of the northern Rockies and into the northern plains. Smoke dispersal conditions will improve considerably by Thursday. Winds aloft will be southerly and surface winds will pick up from the south. A Pacific cold front will reach
the coast late in the day and spread rain eastward into the region by Friday morning. Friday expect cloudy, showery weather most areas with good smoke dispersal conditions and a generally southerly wind early, shifting to northwesterly later in the day. </div>
<div> </div>

<div>3. BURNING INSTRUCTIONS FOR ZONES 624 AND 625 INCLUDING THE WALKER</div>
<div> RANGE PORTION OF ZONE 624</div>
<div>This instruction is valid for burning conducted on Tuesday, November 3, 2009.</div>
<div>==================================================================</div>
<div> </div>
<div>Unfavorable burning situation due to very poor smoke dispersion. Delay ignitions until 10:00am. Avoid ignitions within 20 miles to the SSE through SW of SSRAs. For units that will smolder significantly through the night avoid burning within at least
35 miles to the SSE through SW in or near drainages leading to SSRAs. Verify transport winds away from SSRAs if burning in any other direction. Recommend against burning units that will smolder significantly overnight. Complete ignitions by 3:00pm. </div>
