The Worst is Over as the Storm Crosses Vancouver Island

The latest (8 PM) infrared satellite photo shows the storm now making landfall on Vancouver Island, as the wind begin to ease.  Amazing storm for April.


Here are the maximum winds today.  Some locations on the Oregon and Washington coast gusted to over 70 mph, with most coastal locations getting at least to 40 mph.  40-60 mph gusts in Portland, 35-50 mph gusts around Seattle (with a few getting to the mid-50s.  And 50-60 mph gusts around NW Washington.  At the mountain crests of the Olympics and Cascades, some winds of 90-100 mph were observed.


Destruction Island on the central WA coast got to around 72 knots (83 mph)

Seattle's West Point speed up to 42 knots (48 mph)

And Smith Island, just off of Whidbey Is. hit 58 knots (67 mph)

For Seattle's 520 bridge, winds have climbed to 40-45 mph.


Several hundred thousand people lost power, particularly over Oregon and SW Washington.    An unusual late season event, which will be followed by improving weather over the weekend.

Here are the high wind reports collected by the National Weather Service:

Will Such Storms Increase Under Global Warming? Help Us Determine the Local Impacts of Climate Change

Society needs to know the regional impacts of climate change and several of us at the UW are trying to provide this information with state-of-the-art high resolution climate modeling.  With Federal funding unavailable, we are experimenting with a community funding to build this effort.  If you want more information or are interested in helping, please go here.  The full link is: https://uw.useed.net/projects/822/home    All contributions to the UW are tax deductible.

  1. Bless you Cliff - live in Gig Harbor surrounded by trees - each storm I hang on your every word. Thanks again

  2. We lost power around 5:30ish. Luckily it came back in time for dinner.

    Always learning we are.

  4. The storm skipped my neighborhood in Olympia, just rain and very little wind, talk about microclimates!

  5. So this was an "extraordinary" storm and "probably the "most powerful April storm to approach the Northwest coast during the past half century"? I don't buy that for one second.

    I have lived here long enough to have seen plenty of late March/ early April windstorms that have knocked down trees and brought 60mph+ gusts to the Puget Sound region. We just had one of these in April of 2010 which was arguably more of an event than this. So what, that never happened? Here is your blog on it: http://cliffmass.blogspot.com/2010/04/storm-watch.html

    No big hype on that one... but it dropped to 970-975 mb over Tatoosh (see comment section) and it was nasty. Here is a youtube on it https://www.youtube.com/watch?v=gTVGXjlelYI. It also had a cold front associated with it that brought snow to the Kitsap Peninsula and dumped a large amount of snow in the Cascades. I can't imagine what the hype would have been on that one today... "Storm of the Century!!!!!!!!"

    And then to make it worse today, you have an ask at the end: "Will Such Storms Increase Under Global Warming? Help Us Determine the Local Impacts of Climate Change."

    Go back and read that post from 2010 Cliff. No hype, just science.

    Do you not see the problem with all of this? Longtime fan here Cliff as you know but this one disturbs me.

  6. Sunsnow..... no...that is not really correct. Charlie Phillips (who gave the 970 mb number) was wrong. Look at the model output on my blog... MUCH smaller storm with sea level pressure around 983 hpa....that is much higher. I checked the official analysis as well. That April 2010 storm brought some high winds because it was more compact and closer in, but it was not in the league of the storm we experienced. This week's storm was absolutely unique in size and intensity...look at the normalized anomalies if you are unsure about that. It deserves the hype...it was that unusual. And I think it is an interesting question whether the temporal boundaries of our strong storms might change under global warming...cliff

  7. Cliff - Fair point on size - but 4/2/10 still packed a punch, and in objective wind speed terms was remarkably identical at SeaTac: 4/2/10 = 37/47mph sustained/gust vs. 4/7/17 = 38/47. And that's what I took as the general context throughout this -- the "potency" of the storm, not the size. That's what was emblazoned across headlines.

    But thank you for the comment section and engaging in it. We live in an age of hit and runs on climate or weather issues where debate is not allowed. You embrace the debate and it is good.

    Also... while I still have the floor... can you please come up with a different photo to represent your campaign for the study on regional impacts? A raging forest fire... really? From someone who has been outspoken - and backed it up - that there is scant evidence suggesting a link? And you've paid a price for it! Instead of fear - which is what that photo clearly invokes - how about a Goldfinch on a Rhododendron? I could use a Goldfinch about now. We all could.

  8. In a closed system energy in = energy out. Given that the added heat imbalance imparted to the global energy system is quickly closing in on 2.5 billion Hiroshima size nuclear bombs since 1998, [Skeptical Science] I would assume the weather systems are surely responding as we speak. Weather on steroids if you will.

    People the world over readily accept the scientific fact that changing a patch of South Pacific from warm to cool by only a couple of degrees C, and the resulting comparatively narrow El Nino/La Nina current across the Equatorial Pacific to South America, can have a profound effect on the weather. Not only here in the United States, but to a lesser degree Europe and Africa.
    On the other hand, transforming a much closer, (boarders in many cases), highly reflective patch of earth from significantly bellow freezing to dark open water above freezing, a difference of 10′s of degrees C and its no problem? Get real. An area that is larger than the states of Alaska and Texas combined! World wide science is telling you, and the on the ground reality are raising red flags here.

  9. If the ~50 mph gusts claimed for the station I spent most of the day across the street from were accurate, then 50 mph gusts are a lot less impressive than I was expecting.

    It was a decent storm, but not even the worst I've seen in the last 5 years living north of Seattle.

    It definitely wasn't even in the same league as the Inauguration Day windstorm of 1993.

  10. It blew hard all afternoon, with quite impressive winds at the Admiralty inlet around 7 PM. It crescendoed to a roar near the water.

    Stronger than average, even if it were a November storm.

    ReplyDelete
  11. Ferndale WA took some pretty strong winds on Friday too - I see there was a gust of 84 mph. (I believe that this station is among one of the most accurate in Whatcom County - I've seen gusts of 99 recorded there.)
