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 An upper level trough will support showers across
southwest washington and northwest oregon today and tonight. Dry, but
cold weather is expected Thursday and Thursday night before a warm
front brings another round of rain and mountain snow Friday through
the weekend. The snow levels will start out relatively low Friday
morning, then rise to 1500 to 2000 feet in the afternoon. Showers are
likely to continue into early next week as the upper trough remains
over the pacific northwest.
Short term 830 am update: today through Friday night... Krtx dual
pol doppler radar at 16z showed shower activity across much of the
area. There have been reports of mixed precip near the valley floors
in heavier showers. The kttd profiler suggests the main snow level
was around 1000 ft at 16z. Webcams show sticking snow along highway
26 near brightwood (elev 1000 ft). Check on various cascade snotels
indicate around 5 to 10 inches of snow have fallen since Tue evening.
Will maintain the current advisories.
High pressure filling in behind the departing shortwave will result
in decreasing showers from north to south this afternoon through
tonight. North to northeast flow aloft will help to maintain a
relatively cold air mass over the area tonight. Gradual clearing
combined with this colder airmass will result in widespread
temperatures below freezing. Weak winds and lingering surface
moisture will likely result in areas of freezing fog developing late
tonight into early Thursday.
Dry weather continues Thursday and Thursday night as a transitory
upper ridge moves over the pacific nw. The fog should clear by early
afternoon in most places, but light north winds through the
willamette valley may result in later clearing of low clouds and fog
in the south willamette valley.
Another low drops south from alaska early Friday, and models are
consistent showing over-running precipitation returning
precipitation to SW washington and NW oregon Friday and Friday night.
The snow levels Fri morning will be around 500 ft. However, if precip
arrives a little sooner than expected, snow could fall to the valley
floors. At this point, any valley floor snowfall looks to be minimal
with little to no impact. Increasing onshore low-level flow Fri and
fri evening will raise snow levels. Weishaar
Long term No changes. Previous discussion follows... Saturday
through Tuesday... Models begin the weekend in fairly good agreement,
with another cold upper trough with alaskan origins digging south
into the pacific northwest. A weak low coming down off the coast as
with previous systems, will enhance the chances for showers Friday
night through at least Saturday night. Thermal fields suggest
continued low snow levels, but not likely to impact valley floors
thanks in part to the low level onshore flow. The dynamics look
favorable through for accumulating snow down into the coast range and
cascade foothills. Showers likely to decrease Sunday and Sunday night
as onshore flow weakens.
Operational model solutions diverge sharply Sunday night through
Monday night, with ec most strongly indicating the weekend trough
weakening, and another east-west oriented upper trough redeveloping
further north along or north of the canadian border. A number of the
gefs perturbations, and eventually the GFS operational run shows
this trend, which will likely result in some warming of the air mass|
early next week. For now prefer not to overly commit too much to the
ec or any other model for that matter given the uncertainties, but
will need to keep pops higher than operational GFS pops early next
week, more in line with a blend of nbm, ec and climatology.
Aviation Post frontal showers contiue today with a northwest
flow at the surface and aloft. Expect showers to diminish inthe
afternoon and evening as the flow becomes more northerly. Expect a
mix ofVFR and MVFR CIGS through about 23z, then conditions becoming
primarilyVFR. Mountains obscured at times through about 00z, then
gradual improvement afterwards is expected. There is a chance that
inland TAF sites may have ifr fog develop after 10z tonight.
Kpdx and approaches...VFR prevailing but occasional MVFR CIGS are
possible through about 21z. Showers taper off late in the day and
evening. There is chance of ifr conditions in fog after 10-12z.
Marine Northwest winds gusting to 30 kt today are expected to
weaken below small craft advisory levels as they turn to the
northeast tonight, and continue northeast through Thursday. Another
frontal system dropping down from the north Friday turns winds back
to the west. This system appears to be a little weaker than the
previous system, but is still likely to bring small craft wind gusts
from Friday afternoon through Saturday morning.
Seas peaking today from 14 to 17 feet. Seas gradually subsiding
through the day Thursday, eventually dropping below 10 feet late
Thursday night. Seas build back up above 10 feet on sat.

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.
