As long as I have been doing this a Winter Weather Advisory in the mountains (at or above 8,500 feet) meant 6 to 12 inches of snow. Now, apparently, it means every time it snows. Winter Storm Warnings are supposed to be issued in the mountains when over 12 inches of snow is expected. In the lower elevations, Winter Weather Advisories are usually issued for 3 to 6 inches of snow, and Winter Storm Warnings are issued when over 6 inches of snow is expected.
On one side I understand that other factors like the wind can affect travel, it is winter now, and that happens. On the other side, by always jumping up to a Winter Weather Advisory, I fear it desensitizes people to the true effects of a Winter Weather Advisory or Winter Storm Warning.
The other thing that happens in Ski towns is that people see the Winter Weather Advisory and they get excited about a certain amount of snow coming. Well, let’s take a look at the Euro…
I rarely paste the snow maps but it is early so let’s take a look.
The Euro could be completely wrong. There are other models that have higher precipitation totals.
I do agree the potential for strong winds is very high with this system, and travel could be hazardous early tomorrow morning across the passes and other areas mainly above 7,400 feet. That being said, unless something changes dramatically I do not feel this is going to be a big snow producer. I hope I am wrong.
My next update will be this afternoon. Thanks for following and supporting the site!
