NATIONAL WEATHER SERVICE SEATTLE WA
1247 PM PST MON NOV 24 2014

...HEAVY RAIN IN THE OLYMPICS THIS WEEK COULD CAUSE SOME RIVERS TO FLOOD...

THE OLYMPIC MOUNTAINS COULD SEE TWO TO THREE INCHES OF RAIN TODAY THROUGH
WEDNESDAY MORNING...FOLLOWED BY THREE TO FOUR INCHES WEDNESDAY NIGHT
THROUGH FRIDAY MORNING. THE SNOW LEVEL WILL RISE TO OVER 8000 FEET
THROUGH WEDNESDAY AND THEN REMAIN AT 6000 TO 7000 FEET THURSDAY
INTO FRIDAY. THERE IS A FAIR AMOUNT OF UNCERTAINTY OVER THE
RAINFALL AMOUNTS HOWEVER.

THESE RAINFALL AMOUNTS THAT ARE EXPECTED MEAN THAT FLOODING IS
POSSIBLE ON THE MORE FLOOD-PRONE RIVERS FLOWING OFF OF THE
OLYMPICS. THIS INCLUDES THE SKOKOMISH AND BOGACHIEL RIVERS. OTHER
RIVERS LIKE THE ELWHA AND THE HOH WILL BE RUNNING HIGH AS WELL. IF
FLOODING DOES OCCUR...IT IS MORE LIKELY TO OCCUR DURING THE SECOND
PERIOD OF RAIN.

PEOPLE NEAR FLOOD-PRONE RIVERS IN THIS AREA SHOULD PREPARE FOR
POTENTIAL FLOODING OVER THE NEXT SEVERAL DAYS. STAY TUNED FOR ANY
CHANGES IN THE FORECAST AND THE MOST CURRENT INFORMATION FROM THE
NATIONAL WEATHER SERVICE.
