Good hear from you and others that so far have gotten by this one. Hope all turns out well - unfortunately that can not be said for all.
Guess the winds at the moment when the picture was taken were heading away given the visibility. Hopefully (just guessing based on the one picture and angle) that it was running up to the crest and producing a firebreak of sorts on the back side back towards you
As always - in our thoughts and prayers, for everyone affected
