The fire has made some good runs to the SE with brief periods of NW winds - having all that hot flank has given it plenty of opportunities to squirt out where alignment was good. Think we’ll see some more of this action with any NW winds - SE fingers becoming new heads that end up pushing back to NE with prevailing SW flow.
The SE side is kind of the neglected one, but IMHO has a lot of potential for major spread. I was just talking to 1980s Eldorado IHC Supt Barry Callenberger, though, and he said north winds aren’t as much an issue here til quite a bit later in season. Anyone want to chime in on autumn winds here?
It has already pretty much outflanked Caples Burn, has a lot amount of open country out to the south and east.
Regarding spread toward Tahoe, I am most worried about the alignment the fire will come into once it gets past Twin Bridges. If it becomes established around Camp Sacramento, it will have the whole basin of Sierra-at-Tahoe above it where upcanyon winds, terrain, and fuels align.
Still a lot of terrain between there and Echo Summit that is sheltered from upcanyon winds, with sparse fuels. With smoke laying in heavy after each day’s major run, followed by a couple hours activity each afternoon on following day, it seems like this slow motion train wreck could really drag out for a long time.
