Check out that guy above!  I absolutely love pictures of snowy animals (co-workers at WeatherNation would probably counter that I just love animals, in general…).  Definitely tweet me @ashafferWNTV if you have any fun snow pictures!

Lots of snow from west to east today, wrapping up the first accumulating snow event of the season for Minneapolis/St. Paul.

The peak snowfall total I’ve seen so far? Pipestone, MN at 10″ of snow.

Along with the snow, we’ve seen winds gusting around the nation.  Santa Ana winds are whipping things around in southern California, while the cold front that caused the snow is bringing gusty winds to the Great Lakes.

Below there is a map showing wind speeds for this afternoon – pay close attention to the brighter shades of colors, those indicate high winds.

Not unusual to see high winds in places like Wyoming this time of year – but that doesn’t necessarily mean people like it!  I remember hearing stories while living in Casper for a couple of years that people write their names & addresses onto their garbage can lids… that way they can find them after the

Speaking of winds… I’m fascinated right now by Super Typhoon Haiyan in the western Pacific.

Take a look at this AMAZING image of Haiyan:

It is so amazing to see satellite imagery like that, with a nearly symmetrical storm.

There is a reason this storm is so amazing via satellite, however.  It is EXTREMELY dangerous & strong.  Winds sustained at Category 5 hurricane level, or 161mph sustained winds, and gusting to 195mph gusts.  Imagine that.

Compare it to a tornado, for example.  Below are the wind speeds associated with damage – and you can see how these winds line up with the tornado damage scale:

 

 

So… by reading that chart – the gusts associated with Haiyan would hypothetically produce EF-4 level damage.

Sustained winds from the storm would produce EF-3 level damage.  Yikes.

So where is this superstorm heading?

Unfortunately it is headed RIGHT at the Philippines, and without much dissipation expected.  This will be the 4th crossing of a typhoon over the Philippines this year.  Yikes.

If you include disturbances – my estimation based on the map above would put Haiyan as the 11th tropical disturbance of any strength to move over the islands!

Stay tuned for more!
