<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>

<div> </div>
<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </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 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. Poor to marginal smoke dispersal conditions on Tuesday will further deteriorate Wednesday and Thursday. </div>
<div> </div>
<div> OUTLOOK (TUESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper ridge axis noses over into southeast Alaska and western Canada. This will give northerly flow aloft and keep atmospheric conditions very stable through the week. Expect marginal burning conditions most areas at
least through Friday. </div>

<div> </div>
<div style="padding-left: 36pt; ">Zone 630 and 632:</div>
<div style="padding-left: 36pt; ">Unfavorable burning situation due to very poor smoke dispersion. Delay ignitions until 11:00am. Avoid ignitions within 20 miles to the N through E of SSRAs. For units that will smolder significantly through the night avoid
burning within at least 35 miles to the N through SSE in or near drainages leading to SSRAs. Recommend against burning units that will smolder significantly overnight. Complete ignitions by 3:00pm. </div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Zone 633 - 638:</div>

burning within at least 35 miles in all directions of SSRAs. Recommend against burning units that will smolder significantly overnight. Complete ignitions by 3:00pm. </div>
