Remember just a few months ago when everyone was getting concerned because it hadn’t really rained in 80 days?

Doncha miss those days?

Well, as we’re sure you’re already well aware, the rain has returned.

With a vengeance.

Perhaps the rain gods are making up for lost time?

Anyways, it’s so bad out there that the National Weather Service has issued several warnings, including flood, wind and heavy rainfall – predicting up to three inches to fall during the next 24 hours:

FLOOD WATCH:

…FLOOD WATCH IN EFFECT THROUGH TUESDAY AFTERNOON…

* FLOOD WATCH TO INCLUDE PORTIONS OF WESTERN WASHINGTON…INCLUDING THE FOLLOWING COUNTIES…GRAYS HARBOR… KING…PIERCE…THURSTON.

THESE RIVERS INCLUDE THE LOWER REACHES OF THE CHEHALIS…THE SATSOP…PUYALLUP AND POSSIBLY PORTIONS OF THE SNOQUALMIE RIVER. FLOODING…IF IT OCCURS…MAY BEGIN LATE THIS AFTERNOON OR TONIGHT AND CONTINUE INTO TUESDAY.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

WIND ADVISORY:

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A WIND ADVISORY IS ISSUED WHEN SUSTAINED WINDS OF 30 TO 39 MPH OR GUSTS OF 45 TO 57 MPH ARE LIKELY.

SPECIAL WEATHER STATEMENT:

…HEAVY RAINFALL TODAY WILL LEAD TO INCREASED RISK OF LANDSLIDES IN WESTERN WASHINGTON…

RAINFALL UP TO 1.5 INCHES…WITH LOCALIZED AMOUNTS NEAR 3 INCHES… DURING THE 24 HOURS ENDING AT 8 AM PST HAS INCREASED THE SOIL MOISTURE TO MODERATE LEVELS ACROSS WESTERN WASHINGTON. ADDITIONAL RAINFALL OF UP TO 2 INCHES IS EXPECTED BY LATE THIS EVENING. THIS AMOUNT OF RAIN WILL PUT EXTRA PRESSURE ON SOIL INSTABILITY… LEADING TO A RISK OF SCATTERED LANDSLIDES.

CUMULATIVE RAINFALL OVER THE LAST WEEK HAS SOAKED SOILS TO THE POINT WHERE THE WASHINGTON LANDSLIDE RISK LEVEL WAS MODERATE. THE PREDICTED RAINFALL COULD RAISE THE LEVEL TO HIGH. THE HIGHER THE RISK LEVEL…THE MORE NUMEROUS THE LANDSLIDES ARE LIKELY TO BE.

AREAS ABOVE 5000 FEET IN ELEVATION AND TO NEAR 3000 FEET IN THE CASCADES PASSES WILL SEE MOSTLY SNOW AND NOT BE AFFECTED.

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 AS NOTED IN THE FORECAST ELEVATED RISK LEVEL. A GRADUALLY DIMINISHING RISK OF LANDSLIDES WILL CONTINUE FOR SEVERAL DAYS AFTER THE RAIN ENDS. AREAS MOST SUSCEPTIBLE TO LANDSLIDES UNDER THESE CONDITIONS ARE STEEP COASTAL BLUFFS AND OTHER STEEP HILLSIDES.
