SUBTROPICAL MOISTURE CONTINUES TO STREAM INTO THE REGION.
ADDITIONAL RAINFALL AMOUNTS OF 2 TO 4 INCHES...WITH LOCALIZED
AMOUNTS AS HIGH AS 7 INCHES...CAN BE EXPECTED THROUGH FRIDAY
MORNING. SNOWFALL WILL CONTINUE TO BE MEASURED IN FEET IN SOME OF
THE HIGHER ELEVATIONS OF THE WESTERN U.S...ESPECIALLY IN THE
SIERRA NEVADA RANGE. THE HEAVY SNOW COMBINED WITH STRONG AND
GUSTY WINDS WILL REDUCE VISIBILITIES AND CREATE DANGEROUS TRAVEL
CONDITIONS. THE RAIN AND SNOW WILL CONTINUE THROUGH THE MIDDLE OF
THE WEEK.

PREDICTION CENTER AT 100 AM PST. PLEASE REFER TO YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS
