This current system will die off this evening giving way to the
next system to reach the California-Oregon coast tomorrow
afternoon. Between now and Thursday evening, 1-3 feet of new
snowfall is expected across the Cascades of Washington and Oregon
as well as the higher elevations of Idaho and northwest Wyoming
and 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, western Oregon
and California coastal ranges are expected to receive 2-5 inches
of rainfall into Thursday afternoon, which could lead to flooding.


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.
