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.

Very light rain snow showers are possible north of a susanville
to lovelock line early this morning. Many valley areas have mixed
out low level clouds with much warmer high temperatures expected
the next few days. A weak system is expected late Friday with a
light higher elevation snowfall possible in northeast california
and gusty winds for lower elevations.
A cold front is brushing by the region today bringing chances for
light showers north of lovelock and increased mixing for low
level valleys that have been stuck under strong inversions.
Many valleys in the region were able to mix out low level clouds
and pollutants in the late afternoon with ridge winds increasing
overnight to 60-80 mph. Winds just (~2am) mixed to the surface
around the reno area with few gusts to 20 mph and temperatures
quickly jumping to the mid 40s, so you could say we mixed out.
Main change overnight was to significantly increase the maximum
temperature forecast in the valleys the next few days. Mixing will
allow for clearer conditions and much warmer temperatures in the
valleys the next few days with temperatures jumping back to the
upper 40s to mid 50s.
Another weak system is expected to brush by the region on
Friday. QPF with this system continues to look pretty meager with
only few hundredths expected in the sierra from tahoe north. It's
possible areas as far south as donner summit area could see a few
inches of snow if the wave deepens a bit more, but current
simulations are coming in with minimal accumulation. -zach
Long term Saturday into next week...
main changes were to continue to reduce QPF for Sunday-Sunday night
and also lower precip changes. Other changes included warming
daytime highs with the expected pattern.
A short wave ridge is expected Saturday that will give way to an
incoming trough. Latest model suite continues the trend of a big|
time split with this trough. The ec continues to be a little more
progressive with it, while the GFS and fv3 deterministic runs have
the southern portion becoming a closed low and diving SE along the
This morning, I am trending more toward the GFS fv3 as they have
more support from the ensembles. Even the ec ensemble shows a
significant split. Overall, lowered the threat of precip about 10-
20% across the board for each 6 hour period. That said, it still
looks like the sierra crest will see some light precip, but to the
east it looks minimal now. If the low does close off, the south to
southeast flow ahead of it is unfavorable for spillover.
Behind this trough, a moderate amplitude and mild ridge is expected.
Temperatures will warm under this ridge to about 5-10 degrees above
Gusty winds this morning with ridge gusts of 80 kts or so over the
sierra crest through 16z. Mtn wave turbulence and some localized
llws will be present during this time. After 16z, the surface winds
will become more northerly along with the ridgetop winds. Llws will
cease, but mtn wave turbulence will still occur (along with
potential jet stream turbulence) through 00z.
As for cigs, the low clouds have mixed out, and aside from areas of
cigs near 3000 feet along the oregon border until 18z, it will be
vfr through Thursday.
The next system for Friday will be a wind maker with gusts 40-45
kts for the terminals in and just east of the sierra. Mountain
wave turbulence and llws will be present in these areas as ridge
winds gust to 90 kts. X

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.
