  sneaker waves expected.

* WHERE...Coastal Del Norte, Northern Humboldt Coast and 
  Southwestern Humboldt Counties.

* WHEN...For the High Surf Advisory, from 4 PM Tuesday to 8 AM 
  PST Wednesday. For the Beach Hazards Statement, through

* IMPACTS...Dangerous surfing conditions and localized beach 
  erosion. Beachcombing is highly discouraged! Large, unexpected 
  waves can sweep across the beach without warning, sweeping 
  people into the sea from rocks, jetties, and beaches. These 
  sneaker waves can also move large objects such as logs, 
  crushing anyone caught underneath.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

Large breaking waves along the coast will lead to increased wave
run-up on beaches with waves topping and washing over large rocks
and jetties. These large waves can be erratic and unpredictable.
Use extra caution near the surf zone as these large waves will be
capable of sweeping people into the frigid and turbulent ocean
water. Mariners traversing the bar are urged to exercise extreme
caution or stay in port until the threat subsides. Please contact
the U.S. Coast Guard for information regarding harbor and bar
closures.

AREA FORECAST DISCUSSION
National Weather Service Eureka CA
249 PM PST Sat Dec 2 2023

.SYNOPSIS...A period of heavy rainfall will impact Humboldt and
Del Norte Counties this evening. Gusty ridgetop winds will also
accompany the heavy rain. Additional light to moderate rainfall is
expected Sunday into early next week, with a slight risk of heavy
rainfall forecast to occur during mid week.

&&

.DISCUSSION...A warm front will advance north and east across the
region this evening. As that takes place, 30-40 kt westerly flow
in the 925-700 mb layer combined with a high PWAT airmass will aid
in strong moisture flux that will encounter north-south oriented
ridges in Humboldt and Del Norte Counties. Heavy orographically
induced rainfall rates will be possible as a result, with peak
rates from 0.5 to 1.0 inch per hour supporting a threat for debris
flows across the Smith River Complex Burn Scar, as well as a
threat for urban and small stream flooding. Otherwise, gusts to 40
mph will likely be observed across exposed Del Norte ridges this
evening.

The strongest moisture flux is forecast to shift north into Oregon
by mid Sunday morning, and then shift southward toward Del Norte
County during the afternoon. Current model QPF for Sunday is not
as heavy as what is depicted for Saturday evening, thus hydro
impacts are expected to be less severe. Moist onshore flow then
continues into early next week and will aid in additional light
shower activity. A stronger frontal system is forecast to advance
east across the NERN PAC as well, with hydro hazards generally
focused over WA/OR Monday night into Tuesday. The front is then
forecast to slide south toward NWRN CA Tuesday night into
Wednesday. A midlevel shortwave impulse may interact with the
front and yield an increase in precipitation rates as the front
moves onshore across the EKA CWA. However, that kind of mesoscale
evolution is associated with high uncertainty 3-4 days in advance.
After Wednesday, a progressive upper flow regime is forecast to
persist and aid in additional rainfall.

Garner

&&

.AVIATION...The coastal terminals will continue to experience
periods of moderate to heavy rainfall and gusty southerly winds.
There is a brief lull in activity this afternoon, but a surge of
heavier rain and stronger southerly winds will develop after 0Z.
Gusts over 30 kts at times are probable at CEC. Winds will not be
as strong at ACV, with some gusts over 20 kts possible. Low level
wind shear will develop at CEC with this activity as well,
lingering into early Sunday. Ceilings will range in the MVFR to
IFR range, with periods of low visibility in the heavier rainfall.
Winds will be light in UKI, with lighter rainfall. Ceilings have
been stubborn to lift from IFR, and this will remain an issue into
Sunday at this terminal.

&&

.MARINE...A surge of southerly winds and heavier rainfall will
quickly spread across the waters this afternoon. Gusts will reach
30 kts across the northern zones. This magnitude of southerly
winds will remain near steady through Sunday, and will further
increase and expand south on Monday. The southerlies will begin to
ease Tuesday.

A northwest swell is building in this afternoon. The swell will
peak late tonight through early Sunday morning in the 12 to 14
foot range at 14 seconds. The first of two long period west-
northwest swells will build in on Monday, to the mid teens at 18
seconds. A second larger long period swell will move in on Tuesday
through Wednesday.

&&

.HYDROLOGY...Strong westerly moisture flux will encounter the
complex terrain of Del Norte and Humboldt County this
evening/tonight. Heavy rain with peak rates ranging from 0.5 to
1.0 inch per hour will be possible as a result. Debris flows may
occur due to heavy rain across the Smith River Complex Burn Scar
during the 4 pm to 1 am time period. In addition, some urban and
small stream flooding may be observed. Reference the latest flood
hazard products for more information.
