<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Monday, November 30, 2009 2:30 PM Jim Little</div>
<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">** Generally unfavorable smoke dispersal conditions through the week **</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">An upper level ridge in the eastern Pacific and Gulf of Alaska will dominate weather this week. At the surface flow will go offshore as a strong surface high pressure area drops out of Canada and heads towards the northern
Rockies. With subsiding air aloft mixing heights will be suppressed. Expect very light winds, especially in SW Oregon where the National Weather Service has issued an Air Stagnation Advisory at least through Friday. Poor smoke dispersal conditions on Tuesday
will further deteriorate Wednesday and Thursday. </div>
<div> </div>
<div> </div>
<div>OUTLOOK (TUESDAY-FRIDAY)</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper ridge axis noses over into southeast Alaska and western Canada. This will give light northerly flow aloft and keep atmospheric conditions very stable through the week. Expect unfavorable burning conditions most
areas at least through Friday. </div>
