Statement as of 7:58 AM PST on December 19, 2008

... Winter Storm Watch now in effect from Saturday afternoon
through late Sunday night...

The Winter Storm Watch is now in effect from Saturday afternoon
through late Sunday night.

This developing winter storm will be different from the storm
that brought snow to western Washington Wednesday and Thursday.
As always happens with snow storms over western Washington... the
winds interacting with terrain will determine where the heaviest
snow accumulations will occur... as well as which areas will
receive very little snow accumulation.

Strong east winds will predominate Saturday through Sunday. This
means that the heaviest snow accumulations will most likely be
over the Kitsap peninsula and along Hood Canal... where the east
winds will enhance the snowfall by creating upslope conditions as
they encounter the Olympics. Snow accumulations here could range
from 6 inches to a foot and a half.

Another location where east winds may enhance the snow is along
the western Strait of Juan de Fuca and the north coast where 6 to
15 inches is possible.

The track of the frontal system across southwest Washington and
Oregon means greater snow fall will occur over the southwest part
of western Washington. Snow accumulations of 4 to 10 inches may
be possible over the southwest interior and the central coast. In
addition... local sleet and freezing rain is possible as warm air
aloft from the system moves overhead. Parts of the immediate
coast may change to rain Sunday morning.

There will be a rapid drop off in snow accumulation as you move
east and north of central Puget Sound. The strong east winds
affecting The Lowlands east of Puget Sound will limit snow
accumulations so that anywhere between a trace of snow and two
inches is possible. The Seattle-Tacoma Metro area is in the
transition zone between the Kitsap peninsula and areas east of
Puget Sound... so snow accumulations are especially uncertain.
Total accumulations here through Sunday afternoon could range
from a trace to 4 inches. Up to 4 inches is also possible over
the north interior from Everett to the Canadian border.

Precautionary/preparedness actions...

A Winter Storm Watch means that heavy snow is possible but not
yet certain. The watch functions as advance notice of the
possibility of significant snow... allowing people and communities
to make preparations ahead of the event. Monitor weather
forecasts and Road conditions. Delay travel if possible.
