What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Eureka, CA wrote its last area forecast discussion before this small craft advisory went out at Jan 7, 3:09 PM PST, 5 hours 56 minutes earlier.
Area forecast discussion, Jan 7, 3:09 PM PST, 5 hours 56 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
309 PM PST Sun Jan 7 2018
.SYNOPSIS...Widespread moderate rain is expected throughout the
day Monday and Monday night. Rain will gradually diminish through
the day Tuesday. Periods of light rain will continue in Del Norte
and Humboldt counties through Thursday, with dry conditions
returning everywhere Friday through the weekend.
&&
.DISCUSSION...While rain has not yet begun across Northwest
California as of early Sunday afternoon, steadily increasing cloud
cover offers a bit of foreshadowing as a storm system gradually
evolves offshore. Over roughly the next 12 to 36 hours, a complex
evolution will take place off the coast of California involving
the merger of two separate storm systems, one from the north and
another from the south. Once this merger takes place, the
resulting storm will strengthen and move onto the California
coast, bringing substantial rainfall to the majority of the state,
including much of Northwest California.
Rain is expected to be mostly light initially, beginning first in
the higher elevations this evening before gradually increasing and
spreading into the valleys overnight. Rain will then steadily
increase during through the day Monday as a warm front and later a
cold front moves onshore. Peak rain rates are expected to occur
during the afternoon and evening as the cold front approaches the
coast, and rain may become heavy at times. Rain will gradually
diminish overnight Monday through the day Tuesday. Overall, the
heaviest rain totals in our four county region (Del Norte,
Humboldt, Trinity, Mendocino) are expected to occur across
Mendocino, Southern Humboldt and Southern Trinity counties, where
widespread accumulations of 2 to 3 inches are expected with
locally higher totals along a few coastal ridges. Lighter totals
are expected across Humboldt, Del Norte and Trinity counties,
generally ranging from 1 to 2 inches. Impacts from the expected
rainfall will include swollen creeks and small streams, ponding on
some roadways, and falling rocks on mountain roads. In addition
to the rain, southeast winds will be somewhat gusty along exposed
ridges, with gusts of between 30 and 40 mph expected. Snow levels
are expected to remain high enough to confine snow to the higher
ridges of Trinity county, and well above highway passes.
.REDWOOD VALLEY COMPLEX BURN SCAR...Considering that we have had
very little rainfall over the past month, and that this may very
well be the strongest storm to impact Mendocino county yet this
season, the potential for flash flooding and/or debris flows near
the Redwood Valley burn scar warrants evaluation. At the present
time, forecasted rain rates currently fall well short of
locally established thresholds for flash flooding in the vicinity
of the burn scar, despite the significant overall accumulations.
As such, it appears that the overall threat of flash flooding
around this particular burn scar is low. However, the threat is
not zero, as there is a slight potential for some heavy rain
rates during the late afternoon and evening as the previously
mentioned cold front approaches the coast. It is during this time
frame that debris flows would be most likely, but still with an
overall low potential. This is NOT expected to be the case farther
south near the Sonoma County fires, as rain is expected to be
heavier in this area. Please see the forecast issued by the
Monterey NWS office for more details regarding flash flooding
potential in Sonoma county.
For the remainder of the week, high pressure will gradually build
across the West Coast. However, weak storm systems traveling
along the northern edge of this building high pressure will bring
period of light rain to Del Norte and Humboldt counties Wednesday
and Thursday. Dry conditions will return everywhere Friday into
the weekend, with hints of active weather returning early next
week. /BRC
&&
.AVIATION...Clear skies are giving way to increasing clouds as a
storm system approaches northwest California this afternoon. Any
lingering valley fog and stratus from this morning will likely
remained trapped until the rain arrives later tonight and into
tomorrow morning. The good news for the TAF sites is that they
have been reporting mostly VFR conditions with the exception being
at KUKI as the stratus hasn't completely eroded this afternoon.
Once the storm system arrives, clouds will lower to roughly MVFR
status with a IFR and LIFR conditions being possible during
moderate to heavy rainfall.
&&
.MARINE...An area of low pressure is approaching from the
southwest this afternoon and will bring near gale to gale force
southerly winds on Monday. The strongest winds look to be in the
southern outer waters as the GFS and HiRes models show several
hours with gale force winds. As a result, the Gale Watch for
Monday has been upgraded to a Gale Warning starting late in the
morning and then continuing through the evening.
Once this system passes by the area moderate northerly winds will
return on Tuesday. Wednesday and Thursday there is general
agreement in the models that several systems will bring light to
moderate southerly winds to the waters. Friday into the weekend
both the ECMWF and the GFS are showing high pressure over the area
bringing light to moderate northerly winds.
A long period northwest to west swell is expected to build into
the area late tonight and into Monday morning. Initially it will
be around 2 feet at 19 seconds, but it will quickly build to
around 8 feet 16 seconds around sunrise Monday morning. There will
be a threat for sneaker waves during this time due to expected
set behavior from the long period waves. The ENP shows this swell
remaining around 8 to 10 feet at 15 seconds through much of the
week. Thursday another long period wave is shown by the ENP.
Initial model runs show this to be larger than the current one,
but that may change as it gets closer. MKK/KR
