HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SEATTLE WA
357 PM PST WED JAN 18 2012
...CORRECTED TO ADD SPECIFIC MENTION OF RIVERS...
...FLOOD POTENTIAL THIS WEEKEND FOR SOUTHWEST WASHINGTON...
A WET AND ACTIVE WEATHER PATTERN IS IN PLACE FOR WESTERN
WASHINGTON FOR THE NEXT WEEK. AS WE WIND UP THIS SNOW STORM...WE WILL
BE EVALUATING THE AMOUNT OF WATER EQUIVALENT THAT IS LYING ON THE
GROUND WAITING TO MELT AND RUNOFF IN TO AREA RIVERS.
MEANWHILE...A PACIFIC STORM IS HEADING FOR WESTERN WASHINGTON FOR
FRIDAY INTO SATURDAY THAT WILL BRING RAIN OF ONE HALF TO TWO AND ONE
HALF INCHES BELOW 4000-5000 FEET ELEVATION. MAXIMUM TEMPERATURES WILL
BE IN THE MID FORTIES AND TOGETHER WITH THE WIND AND RAIN...WILL
MELT THE LOWLAND SNOW. THIS AMOUNT OF RUNOFF COULD DRIVE RIVERS IN
LOW ELEVATION BASINS ABOVE FLOOD STAGE. THIS INCLUDES THE CHEHALIS
AND SKOKOMISH RIVERS. ANY FLOODING THAT DOES OCCUR IS EXPECTED TO BE
MINOR. IN ADDITION...THIS COULD PRODUCE URBAN AND SMALL STREAM
PONDING OR FLOODING FROM SNOW AND ICE CLOGGED DRAINS AND CULVERTS
JUST ABOUT ANYWHERE IN THE LOWLANDS OF WESTERN WASHINGTON.
THIS WILL BE A TRICKY SITUATION TO FORECAST AND UNCERTAINTY THAT
THERE WILL OR WILL NOT BE FLOODING IS QUITE HIGH. RAINFALL
INTENSITIES AND THE AMOUNT AND RATE OF LOWLAND SNOW MELT WILL
DETERMINE HOW HIGH THE RIVERS RISE. THERE IS A LOT OF UNCERTAINTY
IN HOW MUCH SNOW WATER THERE IS AND HOW FAST THAT SNOW WILL MELT.
RIVER MODELS DO NOT ALWAYS HANDLE THESE SITUATIONS VERY WELL SO
SPECIFIC RIVER FORECASTS MAY NOT FULLY INDICATE THE EXISTING FLOOD
RISK.
BEYOND THIS WEEKEND...WE WILL CONTINUE TO GET STORMS THAT WILL
CONTINUE TO BUILD RISES ON AREA RIVERS INTO NEXT WEEK FOR
ADDITIONAL PERIODS WHEN THERE MAY BE THE RISK OF FLOODING.
STAY TUNE TO THE LATEST WEATHER AND RIVER FORECASTS AND BULLETINS.
