Here's a good report detailing the cause of this wreckage of trees...
The Strange Case of the Quinault Blow Down: The Ultimate Solution
Let's review the facts
1. A large tree fall occurred on the north side of Lake Quinault around 1:30 AM on January 27th. Many of the trees were old-growth, or at least, very large.
2. The tree fall area was quite limited in size: perhaps a half-mile on a side and extending from the lake toward the crest of about 2500 ft.
3. Several of the trees snapped off and this can only be explained by very strong winds (certainly at least 60-70 mph).
4. The trees fell to the south and thus the winds must have been from the north.
5. None of the limited surface observation locations in the area reported any winds even close to those needed to topple the trees. For example, a site just across the Lake only reported light winds during the tree fall.
5. The strong winds could NOT have been the result of microburst associated with a thunderstorm or strong convection. Weather radar showed no such feature and the lightning detection network had no strikes in the region.
6. An occluded front was approaching the coast at the time of big winds and tree fall.
