...REMARKS...
We are running helicopter operations tomorrow to do final volcano
monitoring equipment updates for winter on the North Side of Mount
St. Helens. Wind fog clouds are most important. The primary LZ is
here https://maps.app.goo.gl/hKJoCAXtQuvdWxSm8 we will be traveling
to Spirit Lake: https://maps.app.goo.gl/Gy6siQ1YqhW4qvnQ6 and inside
the crater: https://maps.app.goo.gl/3s4XUgUNQsETq29e8
We typically watch the weather on aps and Windy.com. But we were told
we could request an spot forecast for 1) the most accurate
information and 2) as a practice opportunity for us at the Cascades
Volcano Observatory to see how to do the process in advance of an
emergency event.
