But the fire rages all night...

From my brief experience fighting fire on a neighbors farm for three days & nights non stop, the nature of fire changes considerably after sunset. Not sure why or how but it does.

A moment for Steve Rucker FFer from the Navato area who gave his all today.

RIP Steve.

Hoping the other three FFers are going to be ok.

During the day, the fire gets a lot of it's momentum from
local weather conditions, which are usually uphill, up canyon winds. At night, the air becomes cool, and usually blows downhill, or down canyon. ( usually..obviously this does not apply with Santa Ana conditions.)
That is why the fire USUALLY "lays down" at night.
