...FLOODING THREAT INCREASING SATURDAY NIGHT THROUGH MONDAY FOR
NORTHWEST OREGON AND SOUTHWEST WASHINGTON RIVERS...

STRONG AND DEEP MOIST WESTERLY FLOW WILL BEGIN CROSSING THE PACNW
COAST SATURDAY MORNING. A VERY LONG FETCH OF MOISTURE IS STRETCHING
ACROSS THE PACIFIC WITH ORIGINS WEST TO THE SOUTH CHINA SEA AND HAS
ABOVE AVERAGE POTENTIAL TO BRING HEAVY RAINS TO THE AREA. AS
SUCH...THIS CONTINUES TO GIVE THE APPEARANCE OF A CLASSIC HIGH
PRECIPITATION ATMOSPHERIC RIVER EVENT WHERE THE DEEP MOIST FLOW WILL
SPEND A SIGNIFICANT AMOUNT OF TIME ON A NEARLY PERPENDICULAR COURSE
AGAINST THE COAST RANGE WITH THE CASCADES TAKING A BIT HIGHER OF THE
IMPACT. LATEST FORECASTS FOR FRIDAY NIGHT THROUGH MONDAY AFTERNOON
BRING  8 TO 12 INCHES OF RAIN TO THE CASCADES AND FOOTHILLS...7 TO
11 INCHES FOR THE COAST RANGE...5 TO 7 INCHES ALONG THE IMMEDIATE
COAST...AND 3 TO 4 INCHES ALONG THE I-5 CORRIDOR.

GIVEN LATEST DATA...IT APPEARS MULTIPLE COAST RANGE RIVERS HAVE A
MODERATE POTENTIAL OF EXCEEDING FLOOD STAGE. ADDITIONALLY...THIS
EVENT HAS SUFFICIENT DEPTH TO BRING SIGNIFICANT RAINS TO THE NORTH
OREGON AND SOUTH WASHINGTON CASCADES WHERE RIVERS WILL ALSO SEE
POTENTIAL FOR NOTABLE FLOODING.

KEEP IN MIND THAT DETAILS WILL ALWAYS BE IN FLUX UNDER THESE
SCENARIOS AS SUBTLE NORTH OR SOUTH SHIFTS COLD MAKE DRAMATIC
DIFFERENCES IN WHICH BASINS RECEIVE EXTENDED PERIODS OF MODERATE TO
HEAVY RAIN. PLEASE CONTINUE TO FOLLOW THE LATEST FORECASTS AND
IMPACTS AS CONDITIONS WARRANT.

...SIGNIFICANT MOUNTAIN SNOWFALL POSSIBLE SUNDAY AFTERNOON INTO
TUESDAY...WITH ANOTHER STORM POSSIBLE ON CHRISTMAS DAY...

INCLEMENT WEATHER WILL BE HANGING AROUND EASTERN UTAH AND WESTERN
COLORADO FOR AT LEAST ANOTHER WEEK AS A SERIES OF PACIFIC STORMS
MOVE THROUGH THE REGION. LIGHT SNOW WILL REMAIN A THREAT MAINLY
ACROSS THE NORTHEAST UTAH AND NORTH-CENTRAL COLORADO MOUNTAINS
THROUGH SUNDAY...WITH A SMALL BREAK COMING FRIDAY AFTERNOON AND
OVERNIGHT.

BY LATE SUNDAY...UPPER LEVEL WINDS WILL BE SWINGING AROUND TO THE
NORTHWEST SENDING A SERIES OF VERY MOIST DISTURBANCES INTO THE
NORTHERN AND CENTRAL MOUNTAINS OF WESTERN COLORADO. THIS FAVORABLE
WIND FLOW COMBINED WITH THE PACIFIC MOISTURE MAY RESULT IN A
PROLONGED PERIOD OF MODERATE TO HEAVY SNOWFALL FROM VAIL PASS
NORTHWARD TO THE WYOMING STATE LINE NEAR STEAMBOAT SPRINGS. EARLY
INDICATIONS SUGGEST WELL OVER A FOOT OF NEW SNOW WILL BE POSSIBLE
BETWEEN SUNDAY AFTERNOON AND LATE TUESDAY EVENING. MUCH OF THE
CENTRAL COLORADO MOUNTAINS WILL ALSO EXPERIENCE SOME SNOW SUNDAY
NIGHT AND MONDAY.

LONG RANGE COMPUTER MODELS SUGGEST ANOTHER STORM WILL PASS THROUGH
THE REGION CHRISTMAS EVE OR ON CHRISTMAS DAY. THIS STORM WILL BE
COLDER WITH THE POTENTIAL TO BRING SNOW TO EVEN THE LOWER VALLEYS
OF EASTERN UTAH AND WESTERN COLORADO.

WITH HEAVY HOLIDAY TRAVEL ANTICIPATED...THE IMPACT FROM ANY
SNOWFALL LATE THIS WEEKEND THROUGH CHRISTMAS DAY MAY RESULT IN
SIGNIFICANT DELAYS. PLAN AHEAD AND CHECK THE LATEST FORECAST
BEFORE TRAVELING ACROSS EASTERN UTAH AND WESTERN COLORADO.
