    Explainer for rapid growth of 2018 Camp Fire in northern California. No paywall.

    10km =~ 6.2 miles!!!!

    "Abstract Extreme fire spread during the 2018 Camp Fire in northern California was driven by organized long‐range spotting tightly coupled to plume dynamics. Doppler radar and satellite observations reveal distinct regions of ember lofting and downwind fallout within the convective column, forming direct pathways for firebrand transport several (up to 10) kilometers ahead of the main fire front. These firebrands ignited dense clusters of new fires that merged into rapidly advancing lobes, producing abrupt surges in fire growth that exceeded expectations based on surface wind and fuel conditions alone."

  6. #PackFire in Mono County California.

    Dark symbols are satellite heat detections within prior 6 hours. This data is not real time and sometimes false positive. There is a *lot* more info in the two links in upper left corner of the map.

    If you are ordered to evacuate please do so. The fire officials have information that you do not.

  7. #PackFire is now 1000+ acres and wind driven. Although it may seem counterintuitive, fast wind-driven fires do occur on Sierra lee side prior to cold frontal passages in fall/winter as strong & dry downslope winds (induced by mountain rain shadow) precede precip. #CAwx #CAfire

  8. Despite heavy precip across much of California today (including on the Sierra West slope/crest), the dry downslope wind-driven #PackFIie has broken out on Sierra east (lee) side & is actively burning along Hwy 395 corridor, threatening some structures near Lake Crowley. #CAfire

  11. New Weather West post out this evening: "Following a cool and wet October, a much warmer and drier November to come across California." I'll talk more about this in Monday's YT livestream, in addition to Hurricane #Melissa. #CAwx #CAfire weatherwest.com/archives/43555

  13. Following today's light (to locally moderate) rainfall in northern California, a strong and persistent ridge appears likely to build across the American West and to linger for some time to come--bringing dry and much warmer than average conditions well into November. #CAwx #CAfire

  15. But look at all that prescribed fire on the ground in NorCal at the moment (thanks to this snapshot from the Watch Duty app!). Conditions where it's not raining are generally quite favorable for getting some "good fire" on the ground at the moment. #CAwx #CAfire

  16. There was actually quite a bit of dry-ish lightning overnight. But fortunately, there are *no* new wildfires of significance despite a handful of igntions. Why? Well, fuel moisture matters! Recent rains greatly increased vegetation moisture, tamping down risk. #CAwx #CAfire

  17. Well, it turns out that "sneaky" cut-off low I mentioned earlier this week ended up generating more extensive elevated convection last night into this AM, with a fair bit of lightning and even (isolated) reports of localized flooding from training showers! #CAwx #CAfire

  21. Less than 2 weeks later on Jan 21, I saw from the air some of the aftermath of the #PalisadesFire. The darkened hills and gaps in city lights were obvious even in the dim light of twilight. I was on a flight descending to Los Angeles for my connection on my trip to Australia. avgeek.social/@ikluft/11386999 #CAfire #CAwx #wildfires #SoCalFires

  22. "How ChatGPT prompts and a lighter led Palisades Fire investigators to a suspected arsonist " by @CNN - Investigation details are becoming public with charges against the man accused of starting the #PalisadesFire that burned 23,000+ acres, destroyed 6800+ structures and killed 12 people in NW Los Angeles metro area during a Santa Ana winds event in January 2025. cnn.com/2025/10/11/us/palisade #CAfire #CAwx #wildfires #SoCalFires

  23. Next week is looking quite active in CA as a high-amplitude flow pattern develops over North Pacific in downstream response to perturbation of jet stream by West Pacific #TyphoonHalong. NorCal looks quite wet & stormy (rain & iso. tstms/mtn snow); SoCal impacts TBD. #CAwx #CAfire

  25. New blog post out just before my 3pm PT YouTube livestream! Hurricane Priscilla moisture to bring big rain event to AZ/SE CA later this week, but significant NorCal rain event also possible next week (blame recurving West Pacific typhoon!). #CAwx #CAfire weatherwest.com/archives/43542

  27. Thunderstorms are potentially possible w/both SoCal remnant moisture & NorCal low (lower odds). These will probably be "wet" storms in all cases, w/little fire risk. Offshore waters remain anomalously warm, which will "juice things up" a bit as well. [3/3] #CAwx #CAfire

  28. While there is still some uncertainty, it now appears that Priscilla's remnant circulation will miss CA to SE but will still bring showers/t-storms to parts of SoCal, esp. south of LA County. Separately, NorCal may see a few showers directly from offshore low. [2/3] #CAwx #CAfire

  29. After another fairly hot and dry spell across California, cooler and more active weather will once again return later this week as remnant moisture from then-former #HurricanePriscilla interacts with an offshore low pressure system. [1/3] #CAwx #CAfire

  33. This, in combination w/recent rainfall, will tamp down still-active PacNW wildfires & also further mitigate NorCal fire season. In some, but not all, places in far NorCal and PacNW, this will probably be "fire season-ending." Little/no rain expected south of SF Bay. #CAwx #CAfire

  34. Remnant moisture from decaying East Pacific Tropical Storm #Juliette, which previously looked like it would just miss CA to southeast, will now likely bring some showers to far SoCal (likely San Diego County only!) over the next 48 hours! #CAwx #CAfire [1/4]

  36. In Lake County, the just-ignited #SkyFire up in Lake County is spreading rapidly in dense brush amid hot and dry conditions. It's not immediately threatening communities at the moment, but has substantial potential to "go big" under current and predicted conditions. #CAwx #CAfire

    Dark symbols are heat detections within the prior 6 hours by the MODIS and VIIRS satellites. This data is not real time and locations are only approximate.

    This area has not burned in over 20 years.

  39. 400-acre fire between Fairplay and Volcano; just south of the Caldor fire burn scar. Hoping CalFire gets a handle on this one soon.
