HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SEATTLE WA
1232 PM PDT FRI NOV 1 2013
...SHARP RISES ON SOME CASCADE RIVERS SATURDAY EVENING...
THERE IS A SLIGHT CHANCE OF MINOR FLOODING SATURDAY EVENING AND
NIGHT FROM A PACIFIC STORM THAT WILL BARREL THROUGH WESTERN
WASHINGTON OVER THE WEEKEND. THIS STRENGTHENING STORM WILL BE MORE
OF A WIND MAKER BUT HEAVY RAIN IS EXPECTED WITH IT TOO AHEAD OF
AND WITH THE PASSAGE OF THE COLD FRONT. THE RIVERS MOST AT RISK OF
EXCEEDING FLOOD FLOW ARE THE TOLT AND PUYALLUP RIVER NEAR ORTING.
THE FORECAST OF 2 TO 3 INCHES OF RAIN IN PARTS OF THE CASCADES
MOSTLY OCCURS OVER A SHORT TIME WHICH ENHANCES THE SURFACE RUNOFF.
THE SNOW LEVEL WILL COME DOWN QUICKLY AFTER THE FRONT PASSES BY
TO AS LOW AS 2500 FEET BY SATURDAY NIGHT. THIS WILL TAKE PLACE
DURING THE LATER PART OF THE HEAVY PRECIPITATION AND THAT WOULD
SHUT OFF MUCH OF THE RUNOFF...AT LEAST FOR THE PUYALLUP. THE TOLT
RIVER BASIN DOESN`T HAVE AS MUCH HIGH ELEVATION TERRAIN AND WILL
BE LESS AFFECTED BY THE LOWERING SNOW LEVEL.
WHILE THE CHANCES OF EXCEEDING FLOOD FLOW ARE LOW...IT IS
SIGNIFICANT ENOUGH TO ISSUE THIS OUTLOOK. PLEASE MONITOR THE
WEATHER AND RIVER FORECASTS FOR ANY CHANGES.
