 High Surf Advisory, Coastal Flood Advisory, Areal Flood Watch  Statement as of 4:26 am PST on December 20, 2014


... High surf advisory remains in effect until 4 PM PST this
afternoon...
... Coastal Flood Advisory remains in effect from 8 am this
morning to 1 PM PST this afternoon...

* high surf will make it dangerous to fish or observe the surf
today. Sneaker waves could surprise unwary beach walkers. Waves
might break on jetties and breakwaters. Waves will run up high
on the beaches and some erosion is possible.

* Tidal overflow is likely late this morning and a coastal Flood
Advisory is in effect. High tide along the coast today will be
from around 10 am til noon. Due to low pressure over the region
tidal anomalies early this morning were around 1.8 feet at 4 am.
Adding that anomaly to the tide table prediction gives a high
tide at Westport late this morning near 12 feet and for La Push
around 11 feet.

Precautionary/preparedness actions...

A high surf advisory means that high surf will affect beaches in
the advisory area... producing rip currents and localized beach
erosion. The coastal Flood Advisory indicates that onshore winds
and tides will combine to generate flooding of low areas along the
shore.






1208 am PST Sat Dec 20 2014

... Flood Watch remains in effect from this afternoon through late
Sunday night...

The Flood Watch continues for

* portions of western Washington... including the following
counties... Grays Harbor... Clallam... Jefferson... Skagit...
Whatcom... King... Lewis... Mason... Pierce... Snohomish... Thurston.

* From this afternoon through late Sunday night

* heavy rain is forecast over western Washington today and
Sunday... especially in the mountains. Strong south flow aloft
will bring heavy rain at times to the coast and Olympics today.
Heavy rain will spread over the Cascades late this afternoon as
strong westerly flow aloft develops. Models currently taper rain
over the Olympics on Sunday but keep heavy rain going in the
Cascades into Sunday evening... especially over the Cascades from
about King County south. The total model rainfall over about 48
hours from this morning through Sunday night amounts to around
three to six inches over the Olympics and central Cascades with
a nine-inch bulls-eye over Mount Rainier. Rainfall over The
Lowlands will generally be an inch or less as the westerly flow
causes a rain shadow east of the Olympics.

* These rainfall amounts are enough to cause flooding. At this
time the rivers most likely to flood are the ones flowing off
the Cascades of King... Pierce... and Lewis counties... as well as
the unusually flood-prone Skokomish River in Mason County. Any
flooding would likely begin Saturday night on the Olympics and
Sunday for the Cascades... with crests Sunday night or Monday.
The exact position of the stream of moisture is uncertain so
this outlook covers the entire olympic peninsula and all of the
Cascades rivers.

Precautionary/preparedness actions...

A Flood Watch means conditions are favorable for flooding but
flooding is not imminent or occurring. Monitor the latest
forecasts from the National Weather Service and be ready to act
quickly if flooding is observed or a warning is issued.
