Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A very large and long period wnw swell will persist overnight, creating hazardous seas with swells of 14 to 20 feet at around 16 to 19 seconds. While the swell will subside into Tuesday, another long period well train will arrive by midweek and result in continued hazardous conditions. A split wind wind flow will develop on Tuesday with breezy southerly winds north of point reyes and locally breezy northerly winds south of point sur. Elsewhere, winds will remain light westerly.

area forecast discussion
national weather service san francisco bay area
1038 pm pst Mon dec 17 2018

Synopsis Large waves will continue to impact the coastline
through Tuesday. A weak system may bring light rain to the far
northern portions of the north bay on Tuesday while the remainder of
the region stays dry. Another weak system will drop into the san
francisco bay area late Thursday into early Friday while the central
coast will likely see little to no rainfall at all. Unsettled
conditions will be possible late in the upcoming weekend and into
early next week.

Discussion As of 9:13 pm pst Monday... High surf warning has
been converted to a high surf advisory through 5 pm Tuesday. Have
completed a few forecast updates this evening as rogue band of
light showers raced through the north bay and portions of the east
bay. Definitely a ridge rider as virtually none of the short
terms models picked up on this although some of the recent hrrr
simulations did. Anyway, fog is now becoming the overnight
concern with santa rosa and napa quickly dropping vsbys. Plenty of
boundary layer rh and developing inversions with anti-cyclonic
flow clearly noted aloft.

Looking ahead to tomorrow will need to keep some slight chance of
precip going for the far north bay as weak warm advection pattern
continues. Most precip will be light and confined to near the
mendo line and essentially north of santa rosa. The rest of the
district will be dry and seasonable with highs in the upper 50s
to lower 60s.

Weds and Thursday look dry with high pressure but the next weak
front approaches by Thursday night into Friday with another chance
of some light rain, mainly for the north bay. Latest GFS shows
better chance of rain around xmas eve. Will see what the 00z euro
shows and update the extended overnight.

Prev discussion As of 2:45 pm pst Monday... The main hazard
across the region in the short-term is the large surf impacting
the coastline where a high surf warning remains in effect. More
information on that below. Otherwise, tranquil weather conditions
persist region-wide in wake of the passing mid upper level trough.

As the one system exits, another is approaching the pacific
northwest coast with mid high level clouds advecting inland across
northern and central california. This system is mainly forecast
to remain north of the region as a weak ridge of high pressure
develops off of the southern california coast. The short-range
models do show enough moisture advection over the far northern
portion of the north bay to produce some very light rain on
Tuesday. However, the majority of the region will remain dry
through midweek with daytime temperatures warming into the 60s
while overnight lows cool into the 40s to lower 50s (near the
coast).

The ridge is then forecast to shift to the east late in the week as
another mid upper level system drops southward into northern
california late in the day Thursday into the overnight hours. At
this time, this system is forecast to weaken as it approaches the
region. Thus, the best chance for measurable rainfall will be over
the north bay and around the san francisco bay area while points
south inland will likely remain dry. Conditions dry out on Friday
with an active pattern suggested to return over the weekend and into
early next week. However, there are no significantly strong storm
systems or atmospheric rivers forecast to directly impact the region
through christmas day.

Aviation As of 10:15 pm pst Monday... For 06z tafs. Upper low
over pacnw spreading moisture into the mid to upper levels this
evening, resulting in few-bkn at 15-20000 ft agl. Lingering low
level moisture is also contributing to some lower clouds and
patchy fog in sheltered valleys and coastal locations. Patchy
dense fog will linger near ksts and possibly klvk into sunrise.

Otherwise, few-bkn clouds in the 800-1500 ft range may develop
across the sf bay area overnight. Otherwise,VFR is expected with
winds under 10 kt through the forecast period.

Vicinity of ksfo...VFR. Intermittent low clouds across the sf bay
tonight may briefly become borderline MVFR ifr. Light winds.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Intermittent MVFRVFR this evening.

Hazy misty near the immediate coast due to sea spray from todays
large breaking waves which could lower visibility down to 6-8sm
range. Light winds.

Beaches As of 10:30 pm pst Monday... Hazardous conditions will
persist along the shoreline tonight through Tuesday as a large
swell train continues to impact the region. Wave energy peaked
through the day Monday and both period and wave height are now on
the downward trend. Large wnw swell of 15 to 20 feet at 16 to 19
seconds is expected tonight into Tuesday, which is sufficient to
generate breakers of 20 to 30 feet, locally higher at favored
break points along the coast. In addition, large wave run up is
possible along the coast, particularly during high tide. As a
result, a high surf advisory replaced the high surf warning
earlier this evening and is in effect through sunset Tuesday. A
different large, long period NW swell train will move into the
waters late Wednesday into Thursday. Do not turn your back on the
ocean and stay aware of your surroundings if visiting the coast.

Marine As of 10:20 pm pst Monday... A very large and long period
wnw swell will persist overnight, creating hazardous seas with
swells of 15 to 20 feet at around 16 to 19 seconds. While the
swell will subside into Tuesday, another long period well train
will arrive by midweek and result in continued hazardous
conditions. A split wind wind flow will develop on Tuesday with
breezy southerly winds north of point reyes and locally breezy
northerly winds south of point sur. Elsewhere, winds will remain
light westerly.
