HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SEATTLE WA
412 PM PST MON DEC 8 2014

...FLOODING IS POSSIBLE IN KING AND THURSTON COUNTIES THIS WEEK...

A PLUME OF SUBTROPICAL MOISTURE WILL BE AIMED AT WESTERN
WASHINGTON THROUGH WEDNESDAY. THE FLOW WILL BE STRONG SOUTHERLY
DURING THIS PERIOD...WHICH IS NOT FAVORABLE FOR SIGNIFICANT
RAINFALL IN KING AND THURSTON COUNTIES DUE TO LACK OF UPSLOPE
FLOW. AMOUNTS DURING THE TWO DAY PERIOD ENDING 4 PM PST WEDNESDAY
ARE FORECAST TO BE MAINLY IN THE 2 TO 3 INCH RANGE...WHICH IS NOT
ENOUGH TO GENERATE RIVER FLOODING.

THERE IS A CHANCE THAT RAINFALL AMOUNTS COULD END UP BEING HIGHER
THAN FORECAST...AND IF THE FLOW DEVELOPS A WESTERLY COMPONENT...
THE POTENTIAL FOR FLOODING ON AREA RIVERS WOULD INCREASE. ALSO...
THERE IS A POSSIBILITY THAT LOCALLY HEAVY RAIN COULD LEAD TO MINOR
URBAN OR SMALL STREAM FLOODING TUESDAY OR WEDNESDAY.

THE THREAT OF FLOODING IS EXPECTED TO BE OVER BY THE END OF THE WEEK.

MONITOR THE FORECASTS FROM THE NATIONAL WEATHER FOR THE LATEST
UPDATES ON THIS SITUATION.
