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 Today will be mostly dry and cloudy with northwest flow.
A weak disturbance moving near the area may produce light rain for sw
washington tonight and Friday. Dry weather expected Friday night
through early next week as strong high pressure returns to the area.
East winds will develop Friday night and result in mostly sunny but
cool weather this weekend. Rain is possible mid next week.
Short term Today through Sunday... Low clouds and patchy fog are
filling in along the coast and the interior valleys early this
morning. A building upper level ridge will keep rain well north of
the area today, but a shortwave upper level trough riding over the
ridge may bring periods of light rain to extreme SW washington
tonight through Friday afternoon. The upper ridge strengthens Friday
evening and n-ne winds develop. Mixing at the lower levels will be
poor, especially on Friday and the stagnant air may compromise the
East winds increase Saturday morning as models forecast the dalles to
troutdale surface pressure gradient of 7 to 9 mb by 8 am.These winds
will dominate through Sunday limiting fog and low clouds at night,
and supporting dry weather with mostly sunny skies and cool breezes.
Wind gusts of 30 to 35 mph are possible for the east portland metro
area and 65 to 75 mph gusts at crown point. The east winds should
help improve air quality near the cascade gaps and the columbia river
gorge, but poor air quality is likely in areas protected from the
east winds. ~tj
Long term No changes. Previous discussion follows... Sunday night
through Wednesday. The strong upper level ridge over the eastern
pacific shifts inland over the pacific northwest. East winds will
likely persist through the columbia river gorge for the start of next
week, but elsewhere winds will remain rather light which could lead
to stagnant conditions under the developing inversion. This pattern
will remain in place through at least early Tuesday until the next
front arrives, but forecast models diverge more significantly by
midweek. In particular, the deterministic ECMWF is about 24 hours
faster with the next frontal system, bringing it into the region
early Tuesday. Trended the forecast towards the nbm, which better
reflects the timing in the GFS and ensemble mean solutions. This|
brings the highest (likely category) pops into the region early
Aviation Varied flight conditions across the area with MVFR to
lifr west of the coast range while interior locations have
predominantly MVFR CIGS vis. There are spots of ifr developing
and satellite ifr probably showing about 60 to 80 percent chance
at interior TAF sites. Various MOS guidance also indicating ifr
cigs vis through around 18z so will allow for that in the next
taf package. Should see improvement for the afternoon with MVFR
toVFR conditions. Later tonight into Friday will probably see
areas of ifr returning for the interior. Coastal areas may have
enough offshore wind to remainVFR.
Pdx and approaches... MVFR prevailing with mist and CIGS around
1500-2500 ft in the area. There is still a decent chance
(roughly 60 percent) that CIGS vsbys may lower into the ifr
category through 18z or so. MVFR should continue into the
afternoon and probably return tonight. mh
Marine A ridge of high pressure will lay over the waters into
Friday, then high pressure will strengthen inland for increasing
n-ne flow through the weekend. Some localized gusts 25-30 kt
will be possible in the offshore flow over the weekend, mainly
below gaps in the coastal terrain. Mh
seas around 10 ft will spread across the waters this morning and
is expected to subside below 10 ft this evening. The incoming
west swell is likely to lead to rough columbia river bar
conditions during the ebbs today and tonight.
Pqr watches warnings advisories
Pz... Small craft advisory for hazardous seas until 8 pm pst this
evening for coastal waters from CAPE shoalwater wa to
florence or out 60 nm.
Small craft advisory for rough columbia river bar from 8 am
this morning to 1 pm pst this afternoon.
Small craft advisory for rough columbia river bar from 5 pm
this afternoon to midnight pst tonight.

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.
