Not a lot of growth on the fire except on eastern flank near La Porte Road, which has steady, but not spectacular growth. The finger that blew out under southwest winds south of Bucks Lake on 9/14 continues to spread slowly through short-range spotting, and this area was the reason they evacuated Meadow Valley yesterday. Even though it is a long ways from the community, they were playing it safe with the forecast wind event, and said due to a lack of resources they might have to abandon perimeter control on this part of the fire if it kept overwhelming them with spotting. This info per Jake Cagle’s very detailed operational briefings on the PNF Facebook Page, which should be the standard PIO product on every large fire, IMHO.
Here are IR maps with red line showing fire perimeter from 9pm last night, 9/17/2020. The yellow line is where the fire was on 9/17/2020 at 3am, and the white line was captured on 9/14/2020 at 12:30 am. The satellite image in the background was from 2pm on 9/16/2020.
