Seattle weather expert Cliff Mass has made the call. It’s a La Niña winter and that means more rain — and lower temperatures in the Pacific Northwest:
It also turns out that there is a greater probability of lowland snow west of the Cascades during La Nina years.
Now, if Seattle’s Mayor McGinn knows whats good for him he would be sharpening those snow plow blades, securing lots of sand and SALT, establishing rational plans for plowing the city, and telling all snow plow operators to avoid his neighborhood. We lost one Mayor to snowappocalypse, two would be an embarrassment. I offered to build a SNOWWATCH web page for the city…no bites yet.
The last La Niña event started in 2007, lasted through early 2009 and was relatively moderate, meteorologist types claim. For a reminder, here’s what December 2008 looked like on Capitol Hill.
The last major La Niña came in 1988/89. Seattle got 14 inches of snow that winter — nearly all of it in February and March.
