This current system will slow down and eventually make landfall in
southwest Oregon by early Thursday morning. The low pressure
system in its wake will strengthen and become the dominate low by
Thursday, before making landfall in northern California. Between
now and Saturday morning, 1-2 feet of new snowfall is expected
across the Cascades of Washington and Oregon, with 1-3 feet across
the northern and central Rockies, in addition to the Shasta and
Siskiyou ranges of northern California. The Sierra Nevada of
eastern California is expected to receive 3-5 feet of new snowfall
with locally higher amounts from this system. Such significant
snowfall carries an avalanche risk and threatens to close major
roadways and interstate routes in the area once heavy snow begins
to pile up. At lower elevations, southwestern Oregon and
California coastal regions are expected to receive 2-5 inches of
rainfall into Thursday evening. The heavy rain could lead to
flooding, especially across the burn scar areas of California. 

The next storm summary will be issued by the Weather Prediction
Center at 100 AM PST. Please refer to your local National Weather
Service office for additional information on this event.
