VESSELS SHOULD AVOID NAVIGATING IN THESE CONDITIONS.

A Gale Warning means winds of 34 to 47 knots are imminent or
occurring. Operating a vessel in gale conditions requires
experience and properly equipped vessels. It is highly
recommended that mariners without the proper experience seek safe
harbor prior to the onset of gale conditions.

vessels should avoid navigating in these conditions.

AREA FORECAST DISCUSSION
National Weather Service Eureka CA
242 PM PDT Fri May 25 2018

.SYNOPSIS...Showers will then dissipate tonight, with drier
conditions developing Sunday through the middle of next week. Much
warmer temperatures are likely across the interior Monday and
Tuesday, while a cooler marine airmass persists along the
immediate coast.

&&

.DISCUSSION...The upper level low centered over the San Francisco
Bay Area continues to bring showers to the area this afternoon.
Persistent cloud cover is expected to limit the potential for
thunderstorms this afternoon and evening.

High pressure starts to build in later tonight as the upper level
low starts to push off to the east late tonight and Saturday. As
this happens the subsidence will help to clear skies across both
the interior and along the coast through the morning on Saturday
Confidence is low on the timing of clearing, especially in the
near coastal areas of Humboldt county such as Blue Lake and
Kneeland. High temperatures inland will start to see some warming,
although highs will only top out in the upper 60s to low 70s.
Saturday night some fog and low clouds may return, but at this
point they are expected to be limited to areas around Humboldt
Bay.

Sunday and Monday high pressure builds into area and temperatures
warm dramatically. Highs in the 80s are expected on Sunday with
continued warming on Monday and highs in the 90s. Stratus and low
clouds are expected to be fairly minimal along the coast and in
the coastal river valleys with the best chance on the Humboldt
county coast.

Tuesday an upper level trough approaching the area will likely
increase the stratus along the coast. Temperatures inland will be
similar or slightly cooler, but the near coastal areas may see
more cooling. Wednesday and Thursday temperatures will continue to
cool as the upper level trough deepens over the west coast. There
is a slight chance for thunderstorms in Trinity county each
afternoon, although the potential looks fairly low.

Friday the trough starts to move out of the area and temperatures
may warm slightly as a brief period of high pressure builds in.
Over the weekend another trough may keep temperatures cooler. MKK

&&

.AVIATION...Easterly Steering flow from an upper low to the south
brought convection to the flying region today. Coastal weather
continued to be blanked by multiple low cloud decks as the marine
layer persisted. Therefore, Cigs and Vis were mostly in/out MVFR-
IFR this morning, even as mid-late morning SHRA & TSRA moved
across the coastal areas, producing VCTS at ACV's terminal. There
were numerous lightning strikes. EKA actually experience at
T-Storm between 7am & 8 AM. Pronounced convective activity started
early across the interior especially in Mendocino where VCTS was
reported around 2AM at UKI. Through the 24HR afternoon TAF period,
The plethora amount of clouds will persist across the region
through the night. Most showers will end by mid Saturday morning
if not earlier as the Low's influence decreases. Then the interior
will become mainly VFR. However, model data maintains a somewhat
consistent if not a little weaker marine layer at the coast
through morning. /TA

&&

.MARINE...Northerly winds have started to increase this
afternoon, particularly across offshore waters and near prominent
points and capes like Point Saint George and Cape Mendocino. Gusts
to 25 kt will be possible in these typical trouble spots this
afternoon and evening. Meanwhile, seas will build and become a bit
steeper, with a mix of northerly wind waves and northwest swell
and significant wave heights between 6 and 9 feet overall.

Winds will weaken slightly early Saturday, but mostly north of
Cape Mendocino, allowing steeper seas to settle for a brief
period. However, winds and steeper seas will continue south of the
Cape, and on Saturday night northerly winds will begin to
increase again across all waters. These winds will continue to
increase through Sunday, and by Sunday night Gale Force winds will
be a possibility. These strong northerly winds are expected to
continue through the remainder of the week as well, so mariners
should prepare for an extended period of large, steep, and
hazardous seas throughout the local waters. /BRC

    Small Craft Advisory until 3 AM PDT Saturday for PZZ450.
