UPDATE: ‘Winter Storm Watch’ Says Up To 15″ Of Snow Possible Over Next 2 Days
UPDATE 3:40 p.m., 1/16/12: The National Weather Service issued a revised ‘Winter Storm Watch‘ Monday afternoon, calling for two more rounds of snow – up to 3 inches through Tuesday, and up to 14 inches through Wednesday.
Also, noted UW Meteorologist Cliff Mass warned on his blog Monday afternoon that this could be “the biggest snowstorm in years”:
“The bottom line is that there is a serious threat on Wednesday of 8-15 inches of snow over the region, with a minimal turn over to rain. The biggest snowstorm in years. Anyway, before anyone goes out and buys a snowblower, lets see what tonight’s runs show. If they continue this trend then Slushmageddon might be replaced by Snowmageddon. In almost any conceivable case, Wednesday morning is going to be very problematic for travel…I suspect there will be a lot of school cancellations and the like.
The main roads around Seattle are in very good shape now, but the Wednesday event could dwarf the weekend snow.”
As always, we encourage our Readers to stock up and be prepared to hunker down to ride this system out. Oh, and don’t forget to actually enjoy the snow!
