...HEAVY RAINFALL TONIGHT THROUGH WEDNESDAY WILL LEAD TO AN
INCREASE RISK OF LANDSLIDES IN WESTERN WASHINGTON...
...STRONG WINDS POSSIBLE ACROSS WESTERN WASHINGTON ON THURSDAY...

HEAVY RAINFALL OF 9 TO 13 INCHES IN THE OLYMPICS AND NORTH
CASCADES WITH GENERALLY 2 TO 6 INCHES ELSEWHERE IS EXPECTED
DURING THE TWO AND HALF DAY PERIOD ENDING LATE WEDNESDAY NIGHT.
THIS AMOUNT OF RAIN WILL PUT EXTRA PRESSURE ON SOIL INSTABILITY...
LEADING TO AN INCREASED RISK OF LANDSLIDES.

WITH AN ELEVATED LANDSLIDE RISK...RAINFALL INDUCED LANDSLIDES ARE
POSSIBLE DURING BURSTS OF INTENSE RAINFALL OR WHEN THERE IS HEAVY
RAINFALL OVER A PERIOD OF A DAY OR TWO. A GRADUALLY DIMINISHING
RISK OF LANDSLIDES WILL CONTINUE FOR SEVERAL DAYS AFTER THE RAIN
ENDS. AREAS MOST SUSCEPTIBLE TO LANDSLIDES ARE STEEP COASTAL
BLUFFS AND OTHER STEEP HILLSIDES.

LOW PRESSURE SYSTEM WILL DEVELOP OFF THE NORTHERN CALIFORNIA
COAST WEDNESDAY NIGHT THEN MOVE INLAND ACROSS WESTERN WASHINGTON
ON THURSDAY. THERE IS STILL A LOT UNCERTAINTY CONCERNING THE EXACT
TRACK AND DEPTH OF THE LOW...WITH ONLY SLIGHT VARIATIONS MAKING A
BIG DIFFERENCE ON THE POTENTIAL IMPACTS. HOWEVER...IT DOES APPEAR
THERE IS SOME THREAT OF STRONG WINDS ACROSS PORTIONS OF WESTERN
WASHINGTON THURSDAY INCLUDING THE GREATER PUGET SOUND URBAN
CORRIDOR. MONITOR THE LATEST FORECASTS FROM THE NATIONAL WEATHER
SERVICE ON THIS POTENTIAL HIGH WIND EVENT.
