The wildfire situation in California and Oregon has now escalated to the point that I can no longer keep track of the countless massive, fast-moving, and potentially very dangerous fires. The geographic scale and intensity of what is transpiring is truly jarring. #CAwx #ORwx twitter.com/weatherdak/sta…..
Just did some rough math. It appears that we're closing in on 600,000 acres burned by lightning-sparked wildfires in Northern California *in just 7 days.* Nearly all such fires are still spreading rapidly. I'm truly at a loss for words. #CAwx #CAfires #CaliforniaWildfires https://t.co/tIqssCaHLZ
I'm not sure that folks outside of #Australia have yet grasped the full magnitude of this widespread and still-escalating catastrophe. Well over 12 million acres (!) have already burned, and it's going to get worse before it gets better. #AustraliaBurning
Updating this thread with last visible satellite frames before sunset. A truly stunning perspective, w/massive wind-driven fires & large dust storm in Washington/Oregon, & vast extent of wildfire smoke extending continuously from California to Kansas. Wow. #CAwx #ORwx #WAwx #COwx twitter.com/Weather_West/s….. https://t.co/bR48yTNerj
Scary footage of pyrocumulus "column collapse" earlier this AM. This occurs when there is temporary interruption in sustained fire updraft strength & air falls rapidly back toward surface--similar to thunderstorm downburst. Extremely dangerous conditions. #CAwx #CAfire #CreekFire twitter.com/__josh/status/…..
Serious situation developing in foothills of Fresno County near #Oakhurst. #CreekFire has exploded in size & intensity at a time when 1000s of visitors have crowded area. Massive pyrocumulus cloud indicative of extreme fire behavior, & #pyrotornado may have occurred.#CAwx #CAfire https://t.co/O3lJUt3Xx1
Incredibly, this slipped in "under the radar" due to the more acute short-term wildfire crisis: 2020 has now eclipsed 2018 for the most acres burned in California in a single year during modern era (2,094,955 acres), & "offshore wind" season has not even arrived yet.#CAwx #CAfire https://t.co/cP6cUYGHBq
You could write an entire meteorology textbook just based on the phenomena visible from this afternoon's wild satellite imagery looking down at the American West. (Thread) #CAwx #WAwx #ORwx #COwx #UTwx #MTwx #IDwx https://t.co/diedDhWG34
Extremely dense & tall smoke plumes from numerous large wildfires, some of which have been generating nocturnal pyrocumulunimbus clouds ("fire thunderstorms"), are almost completely blocking out the sun across some portions of Northern California this morning. #CAwx #CAfire https://t.co/y9evl4u0eq
Wild night in the San Francisco Bay Area. This is probably the most widespread and violent summer thunderstorm event in memory for Bay Area, & it's also one of the hottest nights in years. Convective gusts 60+ mph; enormous amount of (partially dry) lightning. Wow. #CAwx #CAfire https://t.co/Q5AOEQcqR7
@MollyJongFast Like fundamentally misrepresenting climate scientists' public statements on wildfires and climate change? As I've stated on the record numerous times, climate change is clearly making Western wildfire conditions more severe--and is a key driver of the present crisis. https://t.co/bO4M7C1WcQ
It's utterly exhausting to repeatedly watch foreseeable & largely surmountable societal challenges turn into crises because they're widely perceived to be affecting "other people" & would be "too expensive" to address.Striking parallels between #COVID19 & #ClimateChange response.
Update: California heatwave now expected to be much more intense, prolonged, and dangerous than initially anticipated. (Hence, the new blog post.) This one reminds me of July 2006 in many ways... #CAwx #CAfire
"The death rate is only 2%" is the #COVID19 equivalent of "It's only 2 degrees of global mean warming" due to #ClimateChange. Both numbers *sound* small but are actually horrifying and societally-transformative in context.
Massive pyrocumulus cloud developing just northeast of Oroville on Sierra Nevada western slope. I believe this is #ClaremontFire, and is now spreading extremely rapidly southwestward toward northeastern Sacramento Valley foothills. Several communities in the path. #CAwx #CAfire https://t.co/ay4g5pgFkQ
Extremely intense fire updrafts have injected vast amounts of smoke & ash into upper atmosphere as high as 50,000 feet--20,000 above cruising altitude of jet airliners. Dense smoke throughout entire atmospheric column is blocking nearly all sunlight at surface. #CAwx #CAfire twitter.com/Weather_West/s…..
The #GlendowerFire started initially as a brush fire just north of Ashland but has burned straight up Interstate 5 corridor into city of Medford--essentialy becoming urban conflagration. Nearly entire city (pop. 82,000), including downtown, under evac order. #ORwx #OregonFires twitter.com/GreatWinter201…..
Well, it's official: most of California just experienced driest February on record. Locations like Ukiah, Sacramento, Redding, & San Francisco recorded no rain *at all* during a month at peak of the rainy season. Wildfire concerns are elevated this week. #CAwx #CAfire #CAwater https://t.co/apROaZMINm
Satellite imagery this morning depicts vast, dense smoke layer covering most of California, western Oregon & Washington, and a large swath of the adjacent Pacific Ocean. Numerous extremely large wildfires continue to produce huge volume of smoke. (1/2) #CAwx #ORwx #WAwx #CAfire https://t.co/2FkjIIN8Fw
I'm not aware any wildfire-related emergency evacuation airlift anywhere approaching this scale in the United States. Incredible...and very lucky this was an option. Meteorological conditions during this airlift must have been extremely dicey. #CreekFire #CAwx #CAfire twitter.com/ChiefNGB/statu…..
That we're seeing *any* wildfire activity in late February in northern California is extremely unusual--let alone this kind of very active fire behavior currently occurring <10 miles from downtown San Francisco. #SanBruno #CAwx #CAfire twitter.com/ABC7Shack/stat…..
A sobering perspective: the death toll from #COVID19 in California now (greatly) exceeds the cumulative death toll of all earthquakes, wildfires, and floods in the region over the past century...combined. twitter.com/latimes/status…..
A sobering thought: only thing stopping a number of California cities from hitting new all-time record high temperatures Sun may be dense pall of smoke from explosively growing wildfires. Also, I expect CA to set new record for acres burned in modern era by...Monday.#CAwx #CAfire twitter.com/Weather_West/s…..
A truly unbelievable amount of fire on ground tonight across Oregon & California, some of which have decimated smaller towns in the Pacific Northwest and are imminently threatening larger communities. 100s of thousands of acres have burned *just today.* #ORwx #CAwx #OregonFires https://t.co/Xl7Ol511Rr
A meteorological feature I don't think I've seen before--a "smoke cyclone?" Looks like a mid-level low pressure swirl over North Coast--entirely encircled by dense smoke! Plus, bit of shallow convection atop smoke layer to south? Hmmm... cc @nplareau @NWSBayArea @NickyNaus #CAwx https://t.co/QANlM2f2cx
