WEATHER: Storm Coming Sun./Mon.; ‘S’ Word Mentioned for Monday Night


The National Weather Service issued a “Special Weather Statement” early Saturday morning (Dec. 15), warning of a “strong Pacific storm” moving in late Sunday through Monday, and yes – even mentioning the “S” word – possibly coming Monday night, when the snow level is expected to drop to as low as 400 feet.

But don’t worry kids, temps won’t stay low enough for the “S” word to stick around much…at least they think.

First, the statement in its ALL CAPS glory:

…HIGH WINDS…HEAVY MOUNTAIN SNOW…AND COASTAL FLOODING ARE POSSIBLE IN WESTERN WASHINGTON SUNDAY NIGHT AND MONDAY…

A STRONG PACIFIC STORM WILL IMPACT THE REGION LATE SUNDAY THROUGH MONDAY. THIS SYSTEM HAS THE POTENTIAL TO PRODUCE DAMAGING WINDS ON THE COAST SUNDAY NIGHT AND NORTH INTERIOR EARLY MONDAY. ELSEWHERE… IT WILL ALSO BECOME WINDY WITH GUSTS TO 50 MPH POSSIBLE.

LARGE SWELLS OF 20 FEET OR HIGHER ARE PREDICTED FOR MONDAY…AND THIS COULD LEAD TO COASTAL FLOODING…ESPECIALLY IF THE LARGE OCEAN WAVES OCCUR DURING THE TIME OF ASTRONOMICAL HIGH TIDE.

THE MOUNTAINS COULD RECEIVE ANOTHER 1 TO 3 FEET OF SNOW BY LATE IN THE DAY MONDAY FROM THIS UPCOMING SYSTEM…ON TOP OF THE 10 TO 16 INCHES BEING PREDICTED BY MIDDAY SUNDAY.

Also worth noting is a “Coastal Flood Watch,” warning residents near the water of high tides and waves combining for possible flooding Monday morning (Dec. 17):

…COASTAL FLOOD WATCH IN EFFECT FOR MONDAY MORNING…

THE NATIONAL WEATHER SERVICE IN SEATTLE HAS ISSUED A COASTAL FLOOD WATCH…WHICH IS IN EFFECT MONDAY MORNING.

* HAZARD…WAVES AND TIDAL ANOMALY AT HIGH TIDE.

* IMPACTS…TIDAL OVERFLOW AND FLOODING NEAR THE BEACHES.

* TIME OF HIGH TIDE…8 OR 9 AM.

* TIDE TABLE PREDICTION…12.9 FT SEATTLE…9.7 FT PORT TOWNSEND…10.5 FT CHERRY POINT.

* EXPECTED TIDAL ANOMALY…1 TO 2 FEET.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A COASTAL FLOOD WATCH MEANS FLOODING OR BEACH EROSION WILL OCCUR IF WEATHER CONDITIONS DEVELOP AS PREDICTED. RESIDENTS AND LOCAL OFFICIALS SHOULD MONITOR THE SITUATION CLOSELY AND BE PREPARED TO TAKE APPROPRIATE ACTION IF A WARNING IS ISSUED.
