Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Moderate to locally strong northerly winds will prevail over the coastal waters today as high pressure remains over the eastern pacific. Gusty winds will generate steep wind waves creating hazardous sea conditions, especially for smaller vessels. Winds will then diminish late this week as the high pressure weakens and the thermal trough shifts towards the coast.

area forecast discussion
national weather service san francisco bay area
916 am pdt Wed sep 19 2018

Synopsis A warming and drying trend will begin over the area
today and continue into Thursday as onshore flow weakens. Gusty
northerly winds in higher elevations will result in enhanced fire
weather concerns from tonight into Thursday morning, mainly in
the hills of eastern napa county. Temperatures moderate slightly
over the upcoming weekend but will remain near to slightly above
seasonal averages.

Discussion As of 9:16 am pdt Wednesday... The marine layer has
deepened overnight to around 2000 feet, and satellite imagery
shows coastal stratus has pushed well inland through the monterey
bay area filling the salinas valley, and also extending northward
into southern santa clara county. Stratus coverage is much more
patchy over the san francisco bays with oak being the only bay
area airport affected by low ceilings at this time. Surface
pressure gradients are still predominately onshore with 1.1 mb
from sfo to sac, but the northerly gradient from acv-sfo is much
tighter versus 24 hours ago with 5.3 mb compared to 1.9 mb
yesterday at this time. This tight northerly gradient will
produced gusty winds across the north bay mountains, where a fire
weather watch remains in effect through tonight for gusty winds
and poor rh recoveries. Gusty winds are also possible tonight over
the east bay hills as well as the santa cruz mountains.

The upper level trough currently over california will continue to
move to the east as high pressure aloft builds in from the eastern
pacific. This will produce a warming trend over the next few days,
peaking on Thursday when high temperatures are forecast to edge
into the 90s across the warmest inland areas, with 60s and 70s
along the coast.

Latest medium range model runs bring a weak trough across the
pacnw over the weekend with high pressure rebuilding over the
eastern pacific early next week. Thus, temperatures should remain
around normal or slightly above.

Aviation As of 04:28 am pdt Wednesday... For 12z tafs.

Satellite imagery showing patchy stratus around the san mateo
coast, part of the east bay, and over the monterey bay area.

Expecting clearing between 16z-18z.VFR conditions this afternoon
and evening. Most sites expected to remainVFR through the period
aside from possible stratus development tonight for the monterey
taf sites. Onshore winds this afternoon 10-15 kt.

Vicinity of ksfo...VFR, possibility that the terminal could be
occasionally affected this morning by periodic MVFR cigs. Onshore
winds this afternoon around 15 kt.

Sfo bridge approach... .Clouds may move into the approach from the
east bay through late this morning.

Monterey bay terminals... .Ifr CIGS to continue through around
18z-19z.VFR this afternoon and evening. Chance of low cigs
returning tonight, but confidence is low. Onshore winds this
afternoon 10-15 kt.

Marine As of 8:34 am pdt Wednesday... Moderate to locally
strong northerly winds will prevail over the coastal waters today
as high pressure remains over the eastern pacific. Gusty winds
will generate steep wind waves creating hazardous sea conditions,
especially for smaller vessels. Winds will then diminish late this
week as the high pressure weakens and the thermal trough shifts
towards the coast.

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.
