<div> </div>
<div> WEDNESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low pressure area continues to spin over the Pacific Northwest on Tuesday. Skies will be mostly cloudy with a few showers. Cooler air aloft will yield high afternoon mixing heights. Smoke dispersal conditions
will be good. Transport winds will be generally north-northwest to northwest. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level low dissipates Thursday but a broad trough remains over the region. There will still be a few showers around especially during the afternoon and early evening hours. Smoke dispersal conditions will be good
most areas. The trough remains for Friday but weakens and finally by Saturday weak ridging begins to build offshore. Showers are still possible although moisture will be very limited. High mixing heights should give good smoke dispersal conditions for the
end of the week. </div>

<div> Instructions are valid for burning conducted on Wednesday, June 16, 2010.</div>
<div> ==================================================================</div>
<div> </div>
<div style="padding-left: 36pt; ">Zone 630 and 632:</div>
<div style="padding-left: 36pt; ">Avoid ignitions within 12 miles to the WNW through NNW of SSRAs. For units that will smolder significantly through the night avoid burning within at least 20 miles to the WSW through NNW in or near drainages leading to SSRAs.
Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. </div>

<div style="padding-left: 36pt; ">Zone 633 - 638:</div>
<div style="padding-left: 36pt; ">Delay ignitions until 10:00am. Avoid ignitions within 12 miles to the W through NNW of SSRAs. For units that will smolder significantly through the night avoid burning within at least 12 miles to the SW through NNW in or
near drainages leading to SSRAs. No additional restrictions necessary. </div>
