"Don't be fooled by disingenuous "straw man" binaries" is a little long for a bumper sticker, but I do think it's a pretty solid approach to science (and...life).

When homes are densely packed in alignment with the direction of strong fire-season winds, it is nearly almost impossible to cut enough brush to make the homes defensible. Fire burns from house to house, no longer a 'brush fire'.
A neighborhood in the path of #PallisadesFire. 1/4

[Matt Roberts @WxMattt]

Never a good sign when the wx stations start to spike and go offline. Good indication that fire has made it deep into the WUI in N #Altadena. Also matches up with cores of high reflectivity on radar. #EatonFire

[Matt Roberts @WxMattt]

@DonShift3 @camarillopolice Yea looks like a worst case scenario developing here. Would not be surprised if it runs clear down to Spanish Hills 😬

[Matt Roberts @WxMattt]

The Camarillo Heights have dodged a lot of bullets during Santa Ana events over the years. Really terrible WUI for the #MountainFire to move into.

[VCFD PIO @VCFD_PIO]

#MountainFire UPDATE:
The fire has crossed Highway 118 and is now impacting the Camarillo Heights area. Evacuation orders are in effect, and we urge residents to follow these orders for their safety. Several individuals have been injured and transported to local hospitals. Numerous structures are currently threatened.

Due to extreme wind conditions, fixed-wing aircraft are unable to assist in firefighting efforts. Ground crews, helicopters and mutual aid resources are actively working to protect lives and property.

🔥📷 Two of our local Incident Meteorologists sent us these pictures of the fire plumes on the Lava, Boulder, Goat, and Bulldog fires. I think they speak for themselves. Stay safe if you're near any of these fires, updates are likely coming rapidly! #idwx

[Matt Roberts @WxMattt]

Also of note, the #LavaFire plume has entirely ingested the #BoulderFire plume to the southeast.

[Matt Roberts @WxMattt]

Very #DixieFire-esque plume cresting the ridge line and drawing in the upslope flow from the valley below.

[Neil Lareau @nplareau]

Quick look at the structure of the #LavaFire's #pyroCb plume. Very deep, but strongly bent-over in the wind.

[Sophia Bliss @SophiaBlissWx]

(1/3) Very visible pyrocumulus cloud this afternoon. Fires can burn so hot that the rising hot air can create its own weather.

This looks to be from one of the fires in the west central mountains that’s burning very aggressively. The smoke is even visible on radar imagery.

[Matt Roberts @WxMattt]

And so goes the season...#LavaFire absolutely ripping this morning SW of Cascade. Likely burning several thousand acres today #IDFire #IDwx

[Matt Roberts @WxMattt]

Hotspots from the Wiley Flat and Rail Ridge fires are clearly visible, with the Shoe Fly fire intermittently obscured by the other two pyro-anvils

[Matt Roberts @WxMattt]

Okay #FireWx folks what new name do we come up with this year? Three headed #pyroCb convective complex continues tonight in central Oregon due to Shoe Fly, Rail Ridge, and Wiley Flat fires. Pyro-MCS??

[Chip Redmond @wx_chip]

That is a lot of smoke. Fire season is still here.

[Neil Lareau @nplareau]

Another day of active fire growth in #Idaho linked to the increasing southerly flow preceding a trough moving into Oregon and Northern California. Some "filthy" looking #pyroCu.

[Matt Roberts @WxMattt]

@nplareau Our prefrontal pyroCu today. The cooldown can’t come soon enough!

[NWS Boise @NWSBoise]

Tonight's satellite imagery is a sobering one. Dozens of hot spots (red) from the larger wildfires are being detected from GOES-18 this evening. Many of these fires are from recent lightning. #IDwx #ORwx #WAwx #CAwx

[Matt Roberts @WxMattt]

@cartermurphy218 @wrighthydromet @Weather_West Just whats on the public API from automated stations. I'd bet the NPS has something more comprehensive somewhere.

[Matt Roberts @WxMattt]

@cartermurphy218 @wrighthydromet @Weather_West There have been only 6 years since '01 (as far as data goes back) where Tuolumne did *not* drop below 31F in July. Most years it happens a few times.

[Daniel Swain @Weather_West]

Like last summer, a vast sea of #wildfire #smoke from numerous large conflagrations in western Canada is moving SEward into U.S. following record heat. Unlike last year, however, there are now also numerous large smoke plumes from fires in Western U.S.--especially eastern Oregon.

[NWS Boise @NWSBoise]

🔥⚡️Pyrocumulus have once again formed from the #FallsFire north of Burns, Oregon. Several lightning strikes have been detected by satellite over the last hour. #orwx
