The resident reported "the wind came from a really weird direction", which would indicate meso circulations embedded in the larger flow...or williwaws.Damage also included roofs, buildings along the foot of the western slopes of Mount Eyak, and damage to Cannery Row, in Cordova's Waterfront Historical District (serious roof damage, siding and interior damage).  A mobile home was a total loss.

In the Portage area, during the height of the blow, a "40-foot-by-60-foot pole barn rented by Porage resident Steve Mendive was demolished.

Damage from Girdwood to Portage to Hope was estimated at least $100,000 to barns, cabins, buildings, vehicles and trees.  Wind was blowing so hard that it "forced water through the chinks in the Millers' log home".  The wind also ripped away all of Big Game Alaska's signs.
