This current system will slowly move into southwest Oregon by
early Thursday morning. Another low pressure system will follow
and make landfall in northern California Thursday afternoon.
Between now and Sunday 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 3-6 inches
of rainfall into Thursday evening, with locally higher amounts
possible. 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 700 AM PST. Please refer to your local National Weather
Service office for additional information on this event.
