get ready for more stormy weather

Just in time for Christmas. From the National Weather Service:

ANOTHER PACIFIC STORM SYSTEM WILL BRING MORE RAIN AND MOUNTAIN SNOW
TO NORTHERN CALIFORNIA DURING THE CHRISTMAS HOLIDAY WEEKEND. THIS
STORM IS EXPECTED TO APPROACH THE CALIFORNIA COAST FRIDAY NIGHT
AND EARLY SATURDAY THEN SPREAD PRECIPITATION ACROSS NORTHERN
CALIFORNIA SATURDAY AFTERNOON AND EVENING. AT THIS TIME...IT
APPEARS THAT CHRISTMAS EVE WILL REMAIN DRY WITH ONLY LIGHT RAIN OR
MOUNTAIN SNOW POSSIBLE CHRISTMAS MORNING. HEAVIER RAIN AND
MOUNTAIN SNOW ARE EXPECTED BY SATURDAY NIGHT AND SUNDAY MORNING AS
THE MAIN FRONTAL SYSTEM MOVES THROUGH. SHOWERS ARE EXPECTED TO
CONTINUE THROUGH THE DAY SUNDAY ESPECIALLY OVER THE MOUNTAINS SO TRAVEL
DURING THE SECOND HALF OF THE WEEKEND IS LIKELY TO BE IMPACTED AS WELL.

IT IS TOO EARLY TO TELL JUST HOW MUCH PRECIPITATION WILL BE
GENERATED FROM THIS SYSTEM. CURRENT PROJECTIONS HOWEVER INDICATE
AN INCH OR MORE OF RAIN COULD FALL ON THE VALLEY FLOOR OVER THE
WEEKEND...WHILE THE MOUNTAINS COULD SEE ONE TO TWO FEET OF SNOW
ABOVE 7000 FEET BY MONDAY MORNING.

MODERATE SNOW LEVELS ARE EXPECTED WITH THIS STORM. THEY WILL RANGE
FROM 3000 TO 4000 FEET OVER THE SHASTA COUNTY MOUNTAINS...TO 4000
TO 5000 FEET OVER THE NORTHERN SIERRA. THE MAJOR MOUNTAIN PASSES
OF NORTHERN CALIFORNIA WILL LIKELY BE IMPACTED WITH CHAIN CONTROLS
AND TRAVEL DELAYS SATURDAY NIGHT INTO SUNDAY AFTERNOON. PERIODS OF
HEAVY SNOW AND STRONG WINDS MAY LEAD TO WHITE-OUT CONDITIONS AT TIMES.

IF YOU PLAN TO TRAVEL THROUGHOUT NORTHERN CALIFORNIA THIS HOLIDAY
WEEKEND...BE PREPARED FOR UNSETTLED WINTER WEATHER. IN THE
MOUNTAINS...CARRY TIRE CHAINS AND EMERGENCY SUPPLIES AND CHECK THE
LATEST WEATHER AND ROAD REPORTS BEFORE DEPARTURE.
