15 minute time lapse shows it really getting legs after the outflow winds from that thunder cell hit.

AA SAID 300

That’s a good time capture. AA also grounded all aircraft just prior. A good situational awareness trainer for sure.

I was wondering why 3 acres sounded so weird. Thanks for your good ears @firedog1!

#21

There is approximately 3 acres across Chiles Pope Valley Rd but the main fire on Hennessey Ridge is well in excess of that.

The fire isn’t in Napa Valley, it’s more eastern napa county. So the fire will not have the same delta influence that a fire in the valley would.

Per the Berryessa Cam it looks like the fire has reached the west shore of the lake. Can anyone verify if that is the case?

#27

Yes, it reached the west shore several hours ago.

Going to venture a guess that the mapping is going to increase the acreage significantly. There is a whole lot more acres than 10K between Hennessey Ridge Road and the West shore of Lake Berryessa and out to Pleasants Valley Rd.
