Marine Weather and Tides
Shelter Cove, 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 Warm and dry conditions will continue for much of the
next week across the interior, although the warmest conditions are
expected Sunday before temperatures drop very slightly Monday and
beyond. More marine clouds, cooler temperatures and a deeper
marine layer can be expected Sunday night through at least early
Tuesday.

Discussion Interior temperatures remain on track to reach near
100 degrees across interior valleys today, but may fall slightly
short of forecast highs by a degree or two. Still, a heat advisory
will remain in effect for the duration of the afternoon, and those
who are sensitive to heat should take precautions while venturing
outside for the remainder of the day. Welcome relief is expected
overnight thanks to dry conditions and efficient cool air drainage
overnight, although temperatures are expected to reach into the
mid to upper 90s again tomorrow. These temperatures are not quite
hot enough to warrant an additional heat advisory for tomorrow,
but those who are especially sensitive to heat should be mindful
of the forecast for tomorrow regardless. Along the coast, a
relatively shallow marine layer and cloudless conditions have
resulted in a pleasantly mild afternoon, and more of the same can
be expected Sunday as well.

By Sunday night, an approaching trough of low pressure aloft will
begin a gradual cooling trend that will continue through much of
the week. Afternoon temperatures throughout the interior will
settle back down into a slightly more reasonable upper 80s to low
90s range, and will fluctuate slightly through the end of the week
with an overall downward trend. You won't need to break out any
jackets anytime soon, but it will be slightly more pleasant than
the near 100 degree heat interior areas have seen late this
afternoon. Meanwhile, a deepening marine layer Sunday night will
bring widespread marine stratus back to the coast, and also carry
the cool marine layer farther inland than in recent days.

Strengthening winds will likely cut down on the stratus a bit
Tuesday and beyond, but morning clouds will likely continue to
develop around humboldt bay and dissipate in the afternoons
through the end of the week. Brc

Aviation Vfr will prevail today for airfields across northwest
california. Dry, easterly flow will keep most coastal airfieldsVFR
through tonight. However, low clouds should develop around humboldt
bay bringing MVFR ifr conditions to kacv as well as the airfields in
kneeland and fortuna. Ceilings should be restricted to the humboldt
bay area tonight. Kml

Marine Strong high pressure offshore will maintain northerly
winds over the next few days and into most of next week. Gale
force wind gusts will be most prevalent across the outer waters
and near CAPE mendocino through tonight. The pressure gradient
will relax briefly on Sunday, allowing wind gusts to fall below
gale force, and then increase again early next week. These
persistent north winds will generate very steep and building seas
through the rest of the weekend. The existing gale warnings and
small craft advisories will remain in effect. Additional
advisories will be likely on Sunday with warnings possible once
again for early next week. Kml

Fire weather Hot and dry conditions will continue through
Sunday, with poor overnight recoveries expected tonight and near
triple digit temperatures expected again tomorrow afternoon. A
gradual moderating trend can then be expected Monday and beyond,
with slightly improved afternoon temperatures and overnight
recoveries. Still, afternoon temperatures across interior areas
will likely remain near to slightly above normal for much of the
next week. A deepening marine layer Sunday night through at least
Tuesday will bring cool and damp marine layer air farther inland
as well. Breezy north winds along coastal ridges will weaken
slightly Sunday and Monday, but will increase again Tuesday and
remain generally gusty through the week.

Eka watches warnings advisories
Ca... Heat advisory until 9 pm pdt this evening for caz110-111-113.

Northwest california coastal waters... Small craft advisory until 3 am pdt Monday for pzz450-455.

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.
