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.

High pressure will remain centered off the pacific coast over the
next several days. A series of weak storm systems will move over
the top off this ridge into utah and southwest wyoming through the
end of the week, bringing periods of mountain snow accumulations
and temperatures near seasonal normals.
Discussion A highly amplified pattern resides across the conus
per latest h5 analysis, with a long wave trough dominating the
central southern plains, and mean ridging oriented along the west
coast. Locally the forecast area remains under a persistent nw
flow aloft on the backside of the upstream ridge.
A short wave trough embedded in the aforementioned flow continues
to track towards northern utah SW wyoming this hour, with current
placement over SE washington. Ahead of this, have noted modest
waa within a moistening environment across the north, enough to
spark light mountain snow in the north and a few valley snow
showers near the ut id border this morning... A trend that will
continue leading up to passage of said short wave late this
afternoon and tonight. Expecting those latter periods to support
slightly better rates and areal coverage of precip (due to
additional forcing and transition to weak low level caa). Continue
to advertise this in the latest update.
A winter weather advisory remains in place through tonight for
the northern mtns, low end new snow accums only for the
mountains... Little in the way of valley accums outside of an inch
(maybe 2) in the cache wasatch back.
Previous discussion This shortwave departs Thursday leaving a
few lingering light snow showers across the northern mountains
through Thursday night as a trailing weak and mainly dry wave
moves through wyoming. The northwest flow persists, with another
dry continental shortwave passage Friday and Friday night that
could result in some nuisances mountain snow showers as well. The
progression of shortwaves will help keep the valleys mixed enough
to keep the inversion away, and allow temperatures to run near
normal to end the week.|
Long term (after 00z Sunday) A persistent long wave pattern
will continue through the long term forecast period. Extensive
long wave troughing over the eastern central CONUS combined with
an amplified ridge off near the eastern pacific coast will keep
utah in deep north to northwesterly flow through the end of the
This flow pattern will allow occasional continental shortwaves to
dig through the state... Bringing relatively light snow accumulations
and reinforcing already cold temperatures across the state.
As has been the case over the last few days, expect a shortwave to
cross the state Monday. Light snow accumulations can be expected
with this system across mainly the northern and central utah
Aviation Lowering ceilings at the slc terminal through the day
and into early evening is expected... Between 4000 and 6000 feet.
Occasional virga or light snow will develop this afternoon, then
snow showers are expected between 00z and 06z. CIGS may lower to
MVFR between 01z and 04z, with possible brief ifr visibility
restrictions in heavier snow showers. Up to 0.5 inch of snow
accumulation is possible on untreated surfaces through 06z.

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.
