I just saw some interesting wind reports on that web page I provided earlier.  Other wind reports from ASOS' have been in the 50-60 kt range.  Looks the high wnds are now spreading into the Fairbanks CWA.

•12 SE Anchorage [ Co, AK] mesonet reports NON-TSTM WND GST of M77 MPH at 15 Sep, 11:33 PM AKDT -- a wind gust to 77 mph was measured at paradise valley near potter marsh at 1133 pm sat sep 15 2012.

•10 SE Anchorage [ Co, AK] public reports NON-TSTM WND GST of M120 MPH at 16 Sep, 01:00 AM AKDT -- multiple reports from the bear valley subdivision on the anchorage hillside of winds overnight over 100 mph with the peak gusts so far measured at 120 mph between 1am and 4am.

Look's pretty windy then! Though Moose has only recorded 59 mph, I wonder if he is blocked or something.

Just a few random thoughts about this particular event:

To say this one fizzled wouldn’t be accurate – it probably turned out to be solidly average. It just didn’t live up to the apocalyptic predictions and the hype from the local media. No doubt everyone was still on edge from the first storm the previous week.

Though it did feel average, I recorded my highest daily rainfall and highest daily wind run for my station yesterday.

The winds up here always exhibit great variation from one event to another, so different readings from place to place are not unexpected at all.

Having said that, I am a little suspect of some of those really high readings, for a few reasons…

1.   They come from “unofficial stations” – of course that isn’t unusual in itself since mine is unofficial too!
2.   I can see Bear Valley from my house, it’s only the next canyon over from me. And while I would expect some variation, a reading of more than double doesn’t make sense to me.
3.   Those stations must be new. We’ve never really had readings of over 110 mph posted on a regular basis up until recently. 90- 100 mph reports during some of the really strong storms seemed to be the max before.
4.   Before, with my stock Davis anemometer I might have wondered if my wind readings were possibly low. However, I just installed a new RM Young 5103 anemometer – and it was just calibrated – so I am pretty confident about what I recorded.
5.   Just through casual observation from being outside, my readings “feel” about right.
6.   Normally, when gusts do start reaching those speeds, we get lots of stories and news reports about roofs being ripped off and windows blown out – even on the homes up here on the upper hillside built to withstand this. I haven’t seen a single report of anything like that so far – very unusual if wind gusts really were around 120 mph.

Again, I’m not saying those numbers are bogus, but I’m taking them with a grain of salt as well.

The NWS has just posted another High Wind Watch starting tomorrow night for yet another storm! This is starting to shape up as an even more severe winter than last, which was already a record breaker for wind and snowfall!

No matter what the numbers, I have a feeling we are in for a wild ride during winter 2012 -2013!

The next storm is getting started and another high wind warning has been posted. This one is actually looking to be stronger than the last.

And it looks like there's more on the way.   :-(

Storm Train Continues in Southern Alaska

More storms are taking aim at Anchorage and the southern coast of Alaska into the last week of September.
 
During September, storms typically become stronger and more frequent over Alaska, especially near the southern coast, and this September's pattern is living up to climatology and then some.

Apparently, it's a violent storm! Looking at webcams it doesn't look too bad.

The webcams don't even begin to show what's going on right now! Hard to stand up outside. The driving rain is now starting to seep in around my windows. I just heard that flights are being diverted away from the ANC Airport. Also looks like I'm about to lose a tree in the yard.

I've got some videos uploading to youtube right now - I'll post in a bit.

Thanks for posting the You Tube video Moose. Any chance you could shoot some footage of your weather equipment going crazy as well as some shots of your indoor equipment showing the actual readings? I'm always interested in seeing these kind of vids!

Actually I did shoot some video of my anemometer going crazy during the strom. I'll post it when I get a chance. I'm still amazed that the little propeller doesn't explode on those things, but they seem to hold up fine in conditions even harsher than mine.

Things have finally settled down a bit, but the forecast is for yet another strom on Saturday! Enough already!

Hi Moose Whisperer,

Yes Please! That would be great! Crikey, think you've had enough haven't you? Can you see a gap in the weather any time soon?

There is currently a blocking ridge of high pressure over British Columbia that is forcing a strong tropical flow up into the Gulf of Alaska and slamming directly into South Central AK where I am. Supposedly the pattern will persist for at least another week.



The same pattern set up early last December and slammed us with five of these really big storms in a row over a period of two weeks. Whenever the big wind would start to blow, I remember seeing the temp go from 0F to +40F in a matter of minutes. 2 ft of snow would melt in a period of only hours, followed by a day of heavy rain. Then the front would pass and temps would plunge almost as fast as they rose. Another two feet of snow would fall (on top of a glazed Ice ground), only to wait for the cycle to restart in a couple of days. I get exhausted just remembering it, and hope it doesn't happen again this winter!

I've always been amazed at the weather in Alaska. It's like Mother Nature turned the dial to 11.

In my very brief experience in Alaska, I recall waiting to go through the tunnel to Whittier in a downpour (aka: a perfectly nice day in Alaska). As I sat in my warm, dry car, I watched the water pouring off the sides of the mountain in little waterfalls just to be caught by the wind and blown right back up the mountain !

We're expecting a nice storm to develop on Sunday. I've issued a 'personal' weather warning for Sunday on my facebook page.

Finally getting a break. I went to take the dog out for her morning walk and actually had to stop and do a double take to figure out what all of those little lights were up in the sky! Shaping up to be a pretty sunrise on my webcams right now. But the wind and rain are supposed to be back shortly!

Hi Derek,

Are you sure? You're only getting gusts of up to 3.0 mph at the moment! :)
