Can anybody do the math on the wind chill at 155mph and 12 degrees?
Loose calculation here: (12 degrees F-32)/1.8 = -11 C * 155 mph wind = freakin cold!

It's actually -25. According to NOAA, Wind speeds above 40 mph have little additional chilling affect.
I would think that if I was not rolling like tumbleweed across the snowfield, I would get a pretty good wind burn or sandblasting of pellets.
Nice picture Fresh!

120mph at Mission yesterday. Is 155mph a new record?
I spent some time looking through the archived NWAC data today. As far as I can find, the 155 mph gust is the highest wind speed recorded at Camp Muir since that site was installed in September 2006, and also the highest wind recorded at any NWAC site over the full period of data. The previous highest was recorded at Mission Ridge, which reached 137 mph in January 2007 ( see this old thread for discussion on that event and previous Mission Ridge winds over 100 mph).
A list of days with winds over 100 mph at the Muir telemetry site:
06Sep2006: Muir station installed
06Nov2006: 121 mph (16" of rain in 48 hrs at Paradise, park flooded and closed until May)
29Apr2007: 125 mph
30Apr2007: 100 mph
12Nov2007: 119 mph
26Nov2007: 117 mph
02Dec2007: 111 mph
29Feb2008: 109 mph
03Mar2008: 100 mph
23Mar2008: 131 mph (avg 109 mph)
data missing for most of Oct-Nov-Dec 2008
27Jan2009: 110 mph
07Mar2009: 108 mph
15Mar2009: 126 mph
04May2009: 113 mph
17Oct2009: 106 mph
11Mar2010: 101 mph
20Mar2010: 106 mph
28Mar2010: 100 mph
19May2010: 113 mph
15Nov2010: 111 mph
12Jan2011: 109 mph
07Feb2011: 116 mph
11Feb2011: 109 mph
12Feb2011: 155 mph (avg 132 mph, min 107 mph)
There are large amounts of missing wind data at Muir, often for days or weeks at a time, due to the anemometer riming up and freezing solid, and also due to occasional communications problems. Nevertheless, the February 11-12 wind event is clearly exceptional in both magnitude and duration, far beyond any previous storm recorded in the data. Maximum gusts over 100 mph for 27 consecutive hours, average winds over 100 mph for 12 consecutive hours, and sustained winds never dropping below 105 mph for the 2 hour peak.

I've often been curious about the anemometers used at NWAC sites, too, including their calibration and whether any altitude (air density) correction is required. Perhaps Mark or Garth from NWAC can answer? (maybe I should email them).

The summit station there holds the record for highest recorded surface gust at 231 mph. Unreal.

First photo is anemometer (wind speed) and second photo is wind vane ( wind direction).

And not a wisp of cloud or lenticular. I don't know how hard it was blowing, but I must have totalled around 200 pounds with boots, pons, and gear.
I've also heard that the BBQ grill that used to be at Schurman broke a chain tether and blew away in strong winds years ago.

I recall some very strong winds one winter a few years back at White Pass with about three different wind events exceeding 100mph and one perhaps in the mid 130's. I am pretty sure at that time it never hit 155 mph.
The most amazing wind damage I ever saw was on the trail from Carbon River cg towards Spray Park in 1982. About a quarter of a mile of the trail was covered with old growth downfall, the biggest pile of which was nearly 30' tall. I guessed that must have been a 180mph gust or so and was probably caused by the freakish convergence of two outburst flows. There was a cyclonic distribution of the downfall.

The cause of the high winds? An impressive-looking low pressure system, forecast to rapidly strengthen and head NE towards Vancouver Island. This image from the UW model (www.atmos.washington.edu/mm5rt/) shows expected pressure (i.e. geopotential height), temperature, and winds on the 700 millibar pressure surface (at roughly 10000 ft elevation) on Wednesday morning:

The actual measured wind at Camp Muir is often much higher than the free air wind, as much as 50% higher or more, due to the wind accelerating as it flows above and around the massive bulk of Mount Rainier. Here is the wind portion of the forecast during the 137 mph event:

And the actual winds at Muir turned out to be a TOTAL disappointment, only reaching 56 mph, which is pathetic compared to the numerous 100+ mph events. That value seems way too low (especially considering that Paradise reached 43 mph), and it could perhaps be a sign of partial riming of the anemometer which prevented recording a true value.

I had the same thought about rime-caused friction on the anenometer when I saw the telemetry for Muir. It seemed to have trouble getting above 50 mph and was nearly the same for a few hours around the time of the peak winds.

The effects of the wind observed at mission ridge today were amazing. Really cool sastrugi, huge difts(8-10') in some spots, very large cornices and a cat track that I had skied on at around 1330 yesterday was completely gone, what had once been a cat track on a steep hillside was now just a steep slope. The uphill cut on the cat track was probably 10-15' the day before.Don't give up on Mission Ridge yet, they are still in the running with a nice 134 mph gust on 3/10: www.nwac.us/weatherdata/missionridge/10day/

Glad I didn't get out there today, afterall. None of my partners were up for an "adventure". So much for the 4th aspect until snows return.
