California Fire News & Weather

[ghost7]

Forecasted wind gusts, temperatures and humidity for 8PM PT tonight. Pretty much the same as yesterday with significant 60 mph gusts around Palm Springs and through the I10 corridor.

The onshore is still flowing in, but increasing temperatures with the forecasted heat wave may cause the ‘burn off’ of atmospheric moisture to occur earlier in the day and continue on into the evening with reduced overnight rH recoveries and increased transpiration of fuels, contributing to somewhat more active fire behavior for the night shifts.

Bay Area and Central Valley

Southern California

A trade-off may occur if the Pacific wind current turns or calms down, reducing eastern slope winds, but also reducing humidities and the marine layer.

If you look at the coastal alert cams, you can see a sort of interesting phenomena, where the sky overhead is blue and breezy, but the low altitude moisture content just stops and piles up dark condensation right along the water line and on the hills, where just a couple hundred feet of altitude sorts the condensation.

A couple screen caps from the SF peninsula; its windy, but the layer just stops, piles up and drifts back and forth:

This is a view of fire in Calaveras County:

Surely, part of the local Rx. You could see them dragging along the dirt road (maybe recently dozer’d), how the black neatly wraps the scrub, and T-90 passed right over it without a drop.

But for a forecast of sustained winds of 25+ mph over a 3 hour period, some of the rest of the criteria for Red Flag warnings may be present. I ponder whether any fuels curing will be triggered, that fuel moistures will take a hard dip come Friday. This is about as close as you get.

Odd there is no Red Flag for Santa Barbara area…it sounds like the Sundowners could be critical.

Saturday 2PM Humidity

Humidity to 20%. Ventusky uses 10% ruler marks and I think the criteria is 15%.

Saturday 3PM and 7PM Wind Speeds and they will sustain, more or less, through at least 1 three-hour interval.

Not sure about the fuels. The grass is certainly ready to go, and I’m sure a power line down in a drainage full of scrub will light it up. Edge case?

Riverine Attack?

Firefighters were focused on the fire’s southern edge near Pyramid Lake, a popular boating destination that has been closed as a precaution since Sunday.

Officials said firefighters were being ferried across the water and where then climbing into steep terrain to prevent flames from reaching the lake’s northern side.

One commercial property has been destroyed, and one injury has been reported.

Best firing op I ever did was from a boat with a pistol.

There was a wild video on social media of Fish and Game running a terra torch from a swamp fan boat south of the American River. Probably looks like more fun than it is. Maybe.
