<div>ISSUED: Wednesday, June 23, 2010 7:30 AM Update Nick Yonker</div>

<div> </div>
<div style="padding-left: 36pt; ">Upper level trough is moving into the Pacific Northwest quicker than earlier anticipated. Onshore flow has begun over the northern half of the state and wind flow is rather variable over the southern half. Expect increasing
onshore flow today and will thus have to reduce burning opportunities in the Coast Range. </div>
