4:00pm Update: Heavy Rain Moves North

A soaker of a storm so far…here are the rain totals since midnight:

 Notice the sharp increase in rainfall from Salem north…we’ve received almost twice as much in Portland and Vancouver compared to Salem.  Now, as forecast by models, the main rain band had slipped north and should stay there through at least 10pm.   Later tonight, towards daybreak, the whole system slides down to the southeast.  That brings one more round of heavy rain over us for at least a few hours…probably during the early part of the morning commute.  

At PDX, the storm total is about 2.50″ so far…add another 1″ to that through tomorrow morning.  3″ plus for a storm is definitely impressive; luckily all rivers and creeks were quite low to start with due to the drier than average November.

Right now the NWS has 4 flood warnings out for rivers in FOX-12’s viewing area: Nehalem, Wilson, Grays, and Naselle rivers.   Note also the Chehalis River has a flood warning out, forecast to rise 2-4′ above flood stage at Centralia.  This is an important one to watch, because another 2-4′ above that level is when Amtrak and I-5 start getting inundated.  That would be particularly bad on one of the busiest travel days of the year.  Let’s hope the heavy rain band doesn’t sit over the Willapa Hills too long overnight.

    Buoy soundings off N. Vancouver Is (near the low) are at 978 mb now. Yikes.

  2. Wave videos…pictures coming later…

    Most of these are from Cape Disappointment. The waves weren’t as high as I’ve seen them, but the rain was intense!

  3. Does anyone find it ironic that a log truck was hit by a falling tree???

    Also, it looks like a number of those trees fell because a clear cut nearby left the once protected trees exposed to the winds.

    Looks like we’ve tied the record high of 59 today (at the airport). Perhaps the approaching southerlies will bump it up another degree, and we can set temp and precip records in the same day!

  5. Hal in Aims says:

    breeze (only a breeze) just picked up again…..mostly in the tops of the 100ft.+ tall firs……have not had all that much wind today……maybe 30 mph gusts tops…..

  6. I’m sure to many peoples surprise, the NWS just re-issued the Wind Advisory.

    …WIND ADVISORY REMAINS IN EFFECT UNTIL 10 PM PST THIS EVENING FOR THE GREATER PORTLAND AND VANCOUVER METRO AREA…THE WILLAMETTE VALLEY…AND THE LOWER COLUMBIA…

    I just walked in the door at home, looks like I got 1.60″ of rain since midnight. Add that to the 0.86″ from yesterday, that brings my storm total to 2.45″… so far. It’s still raining. Not too shabby!

    Wind? Looks like my peak gust for the day was the 16mph (I mentioned earlier), that came at ~4:30 this morning.

    • 16mph? your anemometer blocked by something? That would be the lowest report by far of anywhere. Mine was 37mph. You sure yours is calibrated correctly?

    • W7ENK says:

      Pretty sure. I spoke to my neighbors for a minute on my way in, they wanted to know where this windstorm was that “I promised them!” 😳

      I even moved my anemometer up to one of the highest points on my antenna tower last night… it’s at ~28 feet now.

    • flurball says:

      I think I’m a little SE of you. My wind didn’t top the gusts of a week or so ago when the NWS canceled the wind advisory in the afternoon and then I started pushing 30 on my partially blocked unit but probably in reality a good 10MPH faster. Nothing approaching that toady at this location. Milwaukie dome effect

  8. Offshore wave of low pressure is moving northeast towards the north Oregon Coast.

    Buoy 46089 – 85 NM WNW of Tillamook, OR

    Atmospheric Pressure: 29.41 in
    Pressure Tendency: -0.12 in ( Falling Rapidly )

  9. Southerly gradients slowly increasing ahead of the offshore wave.

    Winds picking up here on the Westside….looks like the Advisory will hit us soon!

    I was on HWY 6 at 5am this morning and let me tell you…that wind and rain was something I have never been through yet! I had real trouble keeping my car on the road going 25mph! I was trying to record my trip but my camera flew off the dash when a large tree came crashing down and I had to swerve to miss it! What a day!

  11. Hal in Aims says:

    just stopped raining and went dead calm here……….eerie…….mmmmmm

  12. Yevpolo1990 says:

    Getting breezy here in Hillsboro

  13. Garron says:

    I noticed that to, the highest gust are now happening as that new wave of moisture heads north. This sat image really shows how narrow the main band of rain has been since 4:30 AM. Really making a turn to the north the last couple of hours. The barometer is still falling at my location 29.62 2.14″ of rain since midnight.

  15. Ken ( S. Salem 500ft.) says:

    Just had 51 mph gust winds ripin here in Salem

  16. SnowedIn - North Plains says:

    It as suddenly began to rain very heavily here…

  17. Barometer falling, now 29.56 in. Yep, this isn’t over. Wind Advisory may verify yet…..

  18. Astoria just had their peak gust for this event, 58mph.

  19. W7ENK says:

    Won’t it push back down this way once the cold front finally pushes through?

  20. Brad says:

    Costal cities starting to gust near their maximums yesterday… Maybe we do have a surprise coming.

  21. Thanks for the soggy update, Mark.

    I don’t think the winds have peaked yet.

  22. PaulO says:

    Thanks Mark. Rain, rain go away…
