Synopsis Scattered showers will continue to track northwestward
over the southern portion of the CWA this morning as an upper
level low moves into california. A showery and cooler weather
pattern will persist into Tuesday as another low approaches the
pacific northwest and moves into oregon on Monday evening. A
drying trend will then follow for the latter half of the week.

Short term today through Tuesday As of 3 am, radar shows
showers progressing north and northwestward into pierce, mason,
and jefferson counties. 6 hourly rainfall totals have been up to
two-tenths of an inch in some places across lewis county. This
shower activity will continue to progress north and northwestward
early this morning, however it will mainly be confined to areas
south of skagit county. Any lingering activity will dissipate
across the area during the late morning hours, making way for some
sun in a few places this afternoon. Highs will be in the upper
60s to lower 70s today.

Sunday night looks drier, with a few showers just lingering over
the cascades. The next system will approach the pacific northwest
on Monday and will brush past us to the south during the evening
hours. This system will bring additional moisture to western
washington, allowing for the wet and unsettled weather pattern to
persist into Tuesday. Models currently in agreement with a drier
Tuesday evening. Afternoon highs will be below-normal on Monday-
with most areas only getting into the upper 50s-lower 60s.

Temperatures will then become more seasonable Tuesday, with highs
in the mid 60s.

Long term Wednesday through Saturday Current model runs
continue to indicate drying for the latter half of the week, as
western washington resides between an upper level ridge building
over the pacific and an upper level low over the interior west.

Models remain in disagreement regarding the track of the low
across the west coast, but have indicated that some wrap- around
moisture may push back into the pacific northwest at times.

Therefore, have maintained the slight chances for precipitation
throughout the remainder of the week. Highs will be in the upper
60s-lower 70s. 14

Aviation Southeasterly flow aloft will become easterly today as
an upper low off the coast of oregon moves east. Low level onshore
flow will increase through the day. In spite of shower
activity... Skies over W wa this early morning remain generallyVFR
except for uil... Where conditions there have dropped into MVFR. With
showers in the area... Cannot rule out CIGS dipping down into MVFR
conditions from time to time... But overall the prevailing conditions
should remainVFR for most terminals. The exceptions being those
locations that are prone to lower cigs... Such as hqm... Olm and pwt.

Any location seeing MVFR conditions is expected to see CIGS rise
intoVFR during the early afternoon. Shower activity will diminish
through the morning and afternoon... And while chances will not
disappear entirely... Activity will be more scattered.

Ksea...VFR conditions persisting... Although may dip down into the
lower end ofVFR during the early morning hours. Showers are
possible near the terminal... Or may occur briefly... But chances
generally less than 30 pct. Light and variable winds this morning
becoming more westerly this afternoon. Smr

Marine Will cancel the SCA for haz seas over the outer coastal
waters for the morning forecast package... Replacing it with SCA for
westerlies in the strait and adjacent waters. Strait looks to fire
up first... With SCA winds kicking in there this afternoon while the
adjacent waters look to hold off until this evening. Although
another weather system is expected to move over the waters
Monday... Current model solutions seem to have backed away from
previous thoughts regarding wind speeds over the coastal waters and
puget sound reaching SCA criteria. At this time... Speeds look to
remain under 20 kts. However... Current progs do suggest that winds
over the coastal waters to pick up for Tuesday. Regardless... No need
for any additional headlines with the morning forecast. Onshore flow
is expected to dominate for the remainder of the week for advisory
level winds at times both over the coast and strait. Smr

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory from noon today to 5 am pdt Monday for
central u.S. Waters strait of juan de fuca-east entrance
u.S. Waters strait of juan de fuca.

Small craft advisory from 5 pm this afternoon to 5 am pdt Monday
for admiralty inlet-northern inland waters including the

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
