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.

Travel impacts from snow are expected in the sierra this morning,
with rapidly improving road conditions by mid-morning. Cool, showery
weather will continue into the memorial day weekend. However, snow
levels are forecast to rise above 7500 feet from Wednesday evening
onward for diminishing snowfall impacts in the sierra.
Snow has finally begun to impact travel in the sierra north of
highway 50, with donner summit snow-covered with chain controls in
place. Down in the tahoe basin and for highway 50 over echo summit,
roads are just wet so far but some heavier snow is approaching
the crest so occasional slushy accumulations will be possible
along highway 89 and over echo pass for the next few hours. Farther
north to highway 44 in western lassen county, it is snowing but
the road has so far resisted snow coverage with temperatures in
the lower 30s (road likely a bit warmer). There is a window
between ~4-8 am for a little slush to accumulate on highways 44
and 36 (fredonyer pass) west of susanville if heavier showers hit
This afternoon and evening, low pressure currently moving into oregon
will drop over northeast ca and the northern half of nevada. This will
bring scattered to numerous showers, along with a low chance for
thunderstorms, mainly north of highway 50. Any snow showers are
unlikely to impact roads after mid-morning due to strong road heating;
however, if a thunderstorm develops and drops large amounts of snow
pellets there could be brief slushy accumulations above 7000 feet.
The upper low will continue to track southeastward tonight through
Thursday, with wrap-around shower chances continuing as some waves
work around the trough. It currently looks like plenty of cloud cover
and moisture should keep any valleys below 5500 feet from freezing
despite the well below normal afternoon temperatures. As far as wind
impacts, with a tightening pressure gradient and northerly flow a
lake wind advisory may be needed for pyramid lake for Wednesday
and possibly Thursday as flow aligns with the lake's major axis.
Long term Friday through memorial day...
low pressure will remain over ca nv through the memorial day weekend,
with active weather including showers and cool, cloudy conditions.
Friday will be one of the "less showery" days as weak shortwave
ridging moves over the region in between low pressure systems. A|
few showers will still remain on Friday but they should be more
isolated in nature.
A shortwave trough drops along the pacific northwest coast on
Saturday bringing a reinforcing shot of energy to the west coast
trough, cutting off a low pressure over california as we go into
the holiday weekend. Moisture and unstable conditions due to the
cold air aloft will bring widespread convection, especially during
the afternoon and evening hours. Latest models continue to bring
the cut-off low along the central ca coast which will bring even
heavier rainfall amounts to the sierra and western nevada. We have
increased the forecast rainfall amounts due to this trend.
Showers and isolated thunderstorms are likely Saturday and Sunday.
Snow levels will be around 7500-8500 ft, so only the highest
elevations will see accumulating snow with most other areas seeing
rain. Storm total rainfall over the weekend could end up being
rather wet with up to 1" possible according to the latest ensembles.
Anyone with outdoor plans for the memorial day weekend should prepare
for soggy and cool conditions and have a plan b for indoor activities.
A slight chance of thunder may be possible during the afternoon hours
underneath the strongest convection, including snow pellets (graupel)
and light mountain snow in the eastern sierra. Low pressure begins
to slide out of the area on Monday, although showers and cool conditions
remain. May not have too many happy campers this holiday weekend.
A late-season storm system continues to move into the region today
with gusty winds, mountain snow and valley rain. Periods of MVFR ifr
cigs vis and mountain wave turbulence will be likely through this
morning. Snowfall up to a an inch will be possible this morning at
ktrk, ktvl, kmmh, although it will be hard to get anything to stick
to the tarmac during the daylight hours.
Active weather pattern remains through the memorial day weekend,
with periods of MVFR cigs, showers, and a slight chance of thunder
over the weekend. -hoon

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.
