Marine Weather and Tides
Manila, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis Isolated thunderstorm development will be possible
this afternoon and evening across portions of the trinity alps and
yolla bolly mountains. Thereafter, widespread showers with
embedded thunderstorms will become probable Thursday and Friday as
an upper-level disturbance moves east across the region. Drier
and warmer conditions will then develop Sunday into early next
week.

Discussion Wednesdays weather will be similar to Tuesday, with
marine stratus and cool daytime highs expected along the coast,
and isolated thunderstorm shower development occurring over
portions of the trinity alps and yolla bolly mountains. Meanwhile,
a trough over the pacific will begin to evolve into a closed upper
low during the next 24 hours. As the low approaches the ca coast
Thursday into Friday, lobes of ascent will spread downstream
across nwrn ca and aid in a more equitable distribution of shower
probabilities across the region. NAM and GFS model guidance also
hint at the possibility for interior thunderstorms spreading
northwest across the coast of del norte and northern humboldt
counties during Thursday evening night.

Otherwise, the upper low is forecast to pass south and exit east
of the area Friday night into Saturday. The atmosphere will
quickly dry in its wake and favor moderating temperatures Sunday
into early next week. However, the coast may remain cool as north-
northwest surface winds over the coastal waters promote augmented
ocean upwelling beneath a boundary layer inversion, which will
favor stratus development banked up against the coastal mountains.

Aviation Widespread marine coverage overnight, thus impacting
all terminals. Kcec was bouncing between lifr and ifr overnight.

Kacv was faring a little bit better, with conditions fluctuating
between MVFR and ifr. For kuki, it went fromVFR to ifr during the
overnight hours as marine stratus spreads into the area from the
south.

Do expect conditions in kacv and kcec to be in lifr ifr through
the early morning hours, then improve slightly to around ifr
during the day. Conditions will worsen again tonight, bringing
conditions back down to lifr.

For kuki, do expect conditions to improve toVFR later this
morning, but do expect the low cloud deck associated with the
marine stratus to return to the area tonight, thus lowering
conditions once again. Rcl

Marine Light north winds and low seas in store for today,
courtesy of an approaching weak weather system and its associated
weak pressure gradient. Do expect the light winds to continue
through Friday, along with resultant low sea states. Thus, no
marine hazards are in effect.

High pressure will build back into the area for the start of the
memorial day weekend. Do expect moderate north winds for the first
part of the memorial day weekend. Models are indicating on
further increase in north winds for the second half of the
memorial day weekend, with gale force wind gusts and steep seas
expected. Rcl

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.
