805 Weather

PSA 👋🏽, I am now on Bluesky (same handle) & hope to reconnect with many of you over there. My X account will still be maintained & running but I do hope to establish more posting overtime on Bluesky as the app upscales in UI. bsky.app/profile/805wea…

El Niño update: Westerly wind bursts during January were very unusual and record-breaking in some areas. Warm water is now moving across the subsurface Pacific and will probably start to surface in February and March. By mid-2026, ocean-atmosphere El Niño coupling is possible.

In case you missed it live, a full recording of my rapid-response livestream regarding news surrounding the proposed imminent and sudden dismantling of the National Center for Atmospheric Research (NCAR) is now available. youtu.be/FTKW68RqdkE

Holy shit…

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, & disaster research underpinning half a century of progress in prediction, early warning, & increased resilience.

@MichelBrewer Well… I may be standing on a rock after this weekend if the creek behind the house busts its banks. 😀

@805Weather Glad you came out from under 🪨 for this 😂

Okay… I’ll step back out from under my rock for this one. 🫣 That is one wild run coming out of the European model suite tonight… Feast your eyes, but be wary of the modeling whiplash ahead. 00Z ECMWF deterministic model wants to drown Southern California. #CAwx

@realwxforecast I need a good enough reason to come back & this may be it. Same to you!

@805Weather Haven't see you in awhile. Hope you are well. This is good stuff.

@heyhwsitgoing Yep, certainly a crazy deviation from the ensembles thus far & just when we thought models might start backing off from the crazier totals that the three storms already in the pipeline might bring by next Thursday, we get a hot potato like this…

@805Weather lol the EPS is like 1/2 that.

@MichelBrewer You are indeed reading that right but take it with a grain of salt. This is only one model right now with this extreme of a scenario & most of the QPF is stacked from the first three storms already in the forecast through next Thursday. This latest model run upped it to 4 storms.

@805Weather Is that 13 inches over Santa Barbara?

🌧️An atmospheric river will continue to impact California through late Saturday/early Sunday. Heavy rain will shift from Central CA today to Southern CA on Friday. Heavy precipitation may lead to scattered instances of flash flooding, especially near burn scars and steep terrain.

⚠️TSUNAMI WATCH in effect for the California coast. Estimated time of arrival as early as 12:15 AM on July 30. People along the coast: Stand by for further updates. #KnowYourZone at conservation.ca.gov/cgs/tsunami/ma… #CAwx #Tsunami

Updated estimated impact times for areas under a tsunami watch, California impacts would begin just before midnight for the NorCal coast and between 12am-1am for the Bay Area #CAwx 7/29/2025

A TSUNAMI WATCH IS NOW IN EFFECT for coastal San Luis Obispo, Santa Barbara, Ventura, and Los Angeles Counties. An earthquake 8.7 80 miles southeast of Petropavlovsk Kamchatka, Russia. Stay tuned for updates. forecast.weather.gov/wwamap/wwatxtg…

Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

I'll offer an unplanned "pop-up" livestream to discuss the outbreak of widespread #thunderstorms across Southern California this afternoon. Expect a radar and satellite tour! (Yes, this is the second livestream of the day. See you at 4pm PT! #CAwx #LArain youtube.com/live/oHs8H_ryV…

@craigmatthews48 @Weather_West Go to my profile. My buddy just pulled his up & same thing. It appears to be system-wide.

@805Weather @Weather_West I'm getting the same thing 😢

@Weather_West Oddly, enough & assuming it’s unrelated but I just suddenly was banned on your blog just now as well @Weather_West. Disqus algorithm at work?

@Weather_West Hopefully an error but…
