    From a Scientific American article:
    So here we are in an atmospheric river:

    The Weather Channel is a bunch of psycho-freak attention-whores.

    Letting that come back is one thing I'll never forgive Charlies for.


    Now, about that oceanfront property in Nevada .......

    I've lived here since close to the dawn of man :)lol:) and I don't remember ever seeing the storms stack up the way they are.
    We've had large storms, but these are one right after another, and there may be something like six of them.

    NOAA also uses the term.

    The term I've seen is "the Pineapple Express" , since it is starting over the Hawaiian islands and coming to CA.

    Now I know why Colorado is so dry, you are sucking all the moisture out of the air in California!! Seriously, the weather has been so strange lately I dont know what to expect. As a motorcycle rider I have to admit I appreciate all this late fall riding weather but we really do need the moisture.

    That's a bit different and normally means heavier rain and one long trail to the storm.
    These seem to be coming from Alaska.

    That's what makes this set of storms "interesting".

    The original path started as a flow from the Gulf of Alaska dumping a lot of rain (but no snow or hail in our area) and looked like this six hours ago...

    [​IMG]

    ...but has now seems to be lining up to draw tropical moisture into the flow...

    [​IMG]

    ...apparently creating a potential for what we have known in the past as the Pineapple Express. But the 6 day forecast models show the flows merging then separating back out leaving the Alaskan flow. The problem with the Pacific forecast modeling is that beyond 3 days, things get pretty iffy.

    However this distorted but broader full North Pacific view gives a sense of what could be coming down through the Gulf of Alaska after that tropical flow:

    [​IMG]

    This is consistent with the Climate Change models which show the Pacific Northwest getting wetter and warmer because of the Arctic warming.

    We've gotten unusually heavy rains. Over two inches in the last four hours. There's a record salmon run in the Eel River Basin and with this rainfall pattern we're seeing them now in the spawning beds that have been deliberately created in the upper Willits Creek by our little community of Brooktrails Township west of Willits.

    For us in the headwaters mountains flooding is not a problem. There will be localized flooding downstream along the Eel tributaries. But those in the valleys downstream on the Russian River, the situation is a different story. Here's one article Storm's third wave expected to trigger flooding in Hopland, Guerneville.

    The real question is will this continue into January and February. We hope not.

    This is so cool. Any chance it can wipe out California altogether? :D

    Which brings to mind an old song about Ark time (excerpt):


    Old Noah looked out into the driving rain,
    Them Unicorns was hiding, playing silly games,
    Kicking and splashing while the rain was pouring,
    Oh, them silly Unicorns.

    There was green alligators and long-necked geese,
    Some humpty-backed camels and some chimpanzees,
    Noah cried, "Close the doors 'cause the rain is pourin',
    And we just can't wait for no Unicorns."

    The Ark started movin', it drifted with the tide,
    Them Unicorns looked up from the rock and they cried,
    And the waters came down and sorta floated them away,
    That's why you'll never see a Unicorn, to this very day.

    You'll see green alligators and long-necked geese,
    Some humpty-backed camels and some chimpanzees,
    Some cats and rats and elephants, but sure as you're born,
    You're never gonna see no Unicorn.

    We're going to damn up Yosemite Valley, and sell the water to CO and TX! At onerous prices, too.

    And as to CA being wiped out, the East Coast will disappear first: CA is rising thanks to the Pacific Plate, and the East Coast is subsiding. May take a thousand millenium, but you read it here first! :nono::sure:

    We're now in between storms. This satellite loop pretty much indicates a bit more rain seems to be headed our way.:eek2:
