Remarkable view of #BombCyclone west of Oregon & Washington and associated #AtmosphericRiver west of California this PM. Fortunately, the strongest winds will remain well offshore, but very heavy rainfall is likely across portions of northern CA into weekend. #CAwx #ORwx #WAwx

Folks: I am currently experiencing an *exceptionally* high number of requests for interviews & etc. I am doing my best to manage the deluge, but please keep in mind that I'm a "one man team" (there is no one else answering my emails or phone calls). Thanks for your patience!

Signs of some "big time" weather for TBD portions of U.S. West coast over next 10 days. A major #AtmosphericRiver, & perhaps a short sequence of very wet ARs, will affect some section of coast between NorCal & WA--perhaps bringing very heavy rain accumulations. #CAwx #ORwx [1/6]

We are witnessing a genuinely extraordinary, and regionally quite deadly and destructive, period for extreme #weather in the United States. And, quite frankly, the fingerprints of #ClimateChange are all over what has transpired in recent weeks and may yet occur in coming days.

This *gesturing wildly and in every direction* is utterly exhausting.

Wildfire season across interior Southwest kicking into high gear, w/multiple large smoke plumes readily apparent following Red Flag conditions & amid moderate to severe drought. #SouthForkFire/#SaltFire in/near Ruidoso have burned structures & forced mass evacuations. #NMwx #AZwx

Smoke plumes from three active grass/brush fires in NorCal are visible on weather radar this PM. These wind-driven fires are putting out a fair bit of smoke, as well as some shallow pyrocumulus clouds at times. #AeroFire near Copperopolis presently of most concern. #CAfire #CAwx

Visually spectacular "sculpted" supercell thunderstorm near Woodrow on high plains of eastern Colorado earlier today (6/8/24). This storm featured a blue-green & ground-scraping shelf cloud (& dust storm beneath) so wide I could not fully capture even with wide angle lens! #COwx

Well, there it is: @NHC_Pacific has officially issued a Tropical Storm Watch for SoCal. This is the first such watch ever issued for West Coast of United States.

Wind will be a concern, but severe flood risk from very heavy rain will be the much greater threat. #CAwx #Hilary https://t.co/Az2ReagfSB

When the catastrophic floods come, @Weather_West@twitter.com says, "I don’t want to be reflecting in retrospect that we really could have prepared for it and didn’t. Because at this point, I think the warning signs are pretty clear." https://www.latimes.com/environment/story/2023-01-18/california-faces-monumental-dangers-in-future-floods

The recent storm sequence in California--as damaging, disruptive, and (sadly) deadly as it was--is still nowhere near the severity level of plausible events we foresee in the ARkStorm scenarios. The risks are rising in a warming climate...and we need to prepare. #CAwx #CAwater
