The arrival of a new storm on
Friday will lead to more substantial rain, wind and mountain snow for
the Northwest, compared to the current storm.
The new storm will likely tap into some moisture from Neki, which as of this morning, was a hurricane churning west of Hawaii.
Rain will drench the Washington
Cascades initially. However,
snow levels will lower to around 4,000 feet by late Friday night. Some rain
and high-elevation snow will reach northern Oregon as well.
In British Columbia,
snow levels will lower to pass levels along highways
1, 3, 97 and 99 later Friday into Saturday.
Fortunately,
snow levels should not drop to Snoqualmie Pass along
Interstate 90 in Washington during the storm.
Enough rain will fall in low elevations and urban areas of
Seattle,
Tacoma and
Vancouver to cause poor drainage area flooding.
Wind gusts up to 60 mph in western Washington and northwestern Oregon can cause sporadic power outages Friday and Friday night.
The rain will also drench low elevations of
northern Idaho and Montana
Friday night into Saturday, where
snow levels will lower substantially as
well.
Snow,
gusty winds and low visibility can slow travel along
Interstate 90 over the passes in Montana.
The combination of high and intermediate elevation snow and
gusty winds
in the
Cascades and northern
Rockies will pose a threat to hikers who do not retreat to lower elevations
prior to the storm's arrival.
The second storm can bring a foot of snow to the highest elevations of
the Northwest and 30 cm to the mountains of southern
British Columbia.
