Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Synopsis A ridge of high pressyure off the coast will bring
warmer temepratures today, while low pressure to the east keeps a
chance for showers and thunderstorms, mainly for the cascades. On
Friday an upper level low pressure system will move down the british
columbia coast and over the pacific northwest, bringing cooler
temperatures and renewed chances for showers lasting through the
Short term Today through Saturday... The upper low pver the
desert southwest early this morning is expected to lift north
through utah today and into wyoming tonight. Cascades remain on the
northwest periphery of the closed low today, leaving the area open
to a chance for showers and thunderstorms. Areas further west
however are likely to remain dry today and tonight as a ridge of
high pressure aloft offshore presses closer to the coast and raises
heights aloft. This also expected to result in warmer temperatures
for much of the area today as 850 mb temperatures climb several
Models agree on a shortwave moving south down the british columbia
and washington coast Friday, digging in for a closed low sinking
south over the region Friday night. A surface trough of low pressure
trailing the low to the north, brings enhanced low level onshore
flow to the region Friday. This brings a chance for showers back to
the entire region, but pops will be a bit on the conservative side
generally chance category except over terrain in the north, as
moisture is limited to just the very low elevations. A second low
follows the first one down the coastline on Saturday, maintaining a
showery cool air mass for the area.
Long term Saturday night through Wednesday... No changes.
Previous discussion follows. The models agree on the general trend
throughout the extended. A low will slowly track over the forecast
area through Sunday leaving a wake of shortwaves that will keep
chances of precipitation within the forecast through Monday night.
The euro is leaning more towards the wetter side as its low has a
more organized circulation and stronger frontal formation, this
results in more rain. The forecast however, is leaning more towards
the GFS which still shows precipitation but not as heavy. Both
models show heavier precipitation in the cascades Monday night.
A high pressure moving in from off-shore Tuesday will reduce
precipitation for the rest of the extended. A notable feature will be
the inversions that occur Sunday through Tuesday in the early|
morning hours (around 5am); this will increase temperatures above
1500ft by roughly 5 degrees. -bphillips
Aviation MVFR stratus beginning to develop inland will spread
through the rest of the inland sites through Thursday morning.
Coastal sites will drop to ifr through the night and likely not
improve above MVFR during the day Thursday. Inland site should
clear out Thursday afternoon but for some cirrus.
Kpdx and approaches... MVFR stratus returning and lasting through
about 18z or 19z Thursday, thenVFR. Light and variable winds
overnight, become northwest round 10 kt Thursday afternoon. Bowen
Marine Latest buoy obs show winds below 20 kt and they were
marginal earlier even at buoy 89, so have dropped current small
craft advisory for winds. However, it does look like winds will
pick up again out of the northwest behind the current system over
the waters beyond about 15 nm offshore, so added a new small
craft advisory for winds starting 5 pm pdt Thursday.
This northerly wind pattern continues through at the weekend.
It appears winds weaken over the weekend. Meanwhile, seas have
dropped some to 8 to 9 ft at 8 to 10 seconds. Have kept the small
craft advisory for hazardous seas in place as it, but will not
extend as seas will continue to drop a little bit with dominant
wave period remaining around 9 seconds.
Model guidance shows seas exceeding 10 ft again Friday night as
the next low pressure area along the british columbia coast drops
south. Latest spectral guidance has seas peaking around 14 ft in
the northern outer waters. Seas then fall just below 10 ft
Saturday and look to continue falling through Sunday to around 4
to 5 feet. Bowen
Pqr watches warnings advisories
Pz... Small craft advisory for winds from 5 pm this afternoon to 5 am
pdt Friday for waters from CAPE shoalwater wa to florence
or from 10 to 60 nm.
Small craft advisory for hazardous seas until 11 am pdt this
morning for coastal waters from CAPE shoalwater wa to
florence or out 60 nm.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
