Areal Flood Advisory 21, NWS Eureka, CA

AREA FORECAST DISCUSSION
National Weather Service Eureka CA
332 PM PDT THU OCT 13 2016

.SYNOPSIS...
The first in a series of strong pacific fronts will arrive impact
the area this evening and overnight. Additional storm systems will
cross the region through the weekend and into Monday. Periods of
heavy rain and high winds are likely through this time.

&&

.DISCUSSION...
The much-talked about period of active weather is in progress across
portions of the forecast area, with Doppler radar showing a steady
band of moderate to locally heavy rainfall stretching from the
northern outer waters through Del Norte County, and to points north
and east. Observations show many locations across Del Norte County
having received 1 to 2 inches of rainfall so far. Winds at higher
elevations across this county and near the King Range in
southwestern Humboldt have been gusting to around 50 mph. These
winds will continue to increase this evening, with gusts near 45 mph
along the Redwood Coast and approaching 60 to perhaps 70 mph for
locations above 2000 feet still expected tonight. The steadier rain
will also drop south through the evening while increasing in
intensity. Overall, the forecast is on track compared to previous
issuance's, with just a slight delay in timing.

For your Friday, the first system will be slowly moving away from
the region while the next storm takes aim on the region. Rainfall
intensity and coverage will decrease during the day, with the winds
relaxing some as well. This will be short-lived though, as an even
stronger storm system will affect northwestern California on
Saturday. Rainfall amounts and wind speeds will be similar to what
we will see this evening, with some increase in either of these
values a distinct possibility given the stronger dynamics associated
with this next storm. Periods of moderate to heavy rainfall will
continue on Sunday, before things start to settle down by Monday
evening. High pressure will build across the region for the
remainder of the week, putting an end to our rainfall chances. /PD

&&

.AVIATION...
An approaching front will bring heavy rain and strong gusty winds
to the coastal terminals tonight. Mostly MVFR conditions are
expected, however heavy rain at times will produce ifr ceilings
and reduced vsbys this evening. Low level wind shear will also be
possible this evening with the passage of the front from 03z to
06z. Conditions will also deteriorate at KUKI tonight as the front
and heavy rain slowly moves southward through the night.

&&

.MARINE...
Winds have been slow to increase today, but expect a quick
ramp up late this afternoon into early this evening as a vigorous
frontal boundary moves through the coastal waters. We are still
expecting winds to howl for a brief time and gusts to 55 kt are
still possible from Cape Mendo northward. Gale force gusts to 45 kt
are much more probable. Winds will start to diminish below GALE
after midnight, though the southern section of Mendocino waters may
continue to see GALE force gusts around 35 kt past midnight. Winds
will ease up across the board on Friday. Another potent fall storm
will begin to take shape by Friday night and new headlines for GALE
and STORM force winds will be necessary. The faster and stronger GFS
is preferred here, though blended some of the NAM12 into the wind
forecast.

Large westerly-northwesterly swell will build tonight. Open ocean
swell will build to 15 to 17 feet at 16 seconds which should result
in breakers around 22 feet by Friday morning. Even though this is
just under our high surf advisory criteria, there still may be
increased wave run up at the beaches due to the summer time sand
profiles. A high surf advisory has been hoisted for this reason.
A coastal flood advisory has also been hoisted. Tidal anomalies have
been just under a foot. With sustained southerly winds offshore and
an incoming westerly swell, the anomalies may increase by 2 to 3
feet by midday Friday. High tide will be about 7.4ft at 11am Friday.

Another burst of westerly winds will generate a new push of water
over the weekend. The swell generated from the weekend storm will be
higher and breakers may reach 23-27 feet. More HIGH SURF is expected.
Coastal flooding will also be possible.

&&

.HYDROLOGY...
Rainfall totals of 2 to 4 inches are expected during the next 24
hours, with the highest totals likely occurring across Humboldt and
Del Norte counties. Given the dry soil conditions, only localized
flooding in poor drainage areas are anticipated. The rivers and
creeks will likely see a sharp rise. However, they will remain below
flood stage. The one thing this will do is "pre-condition" the soils
for the next storm on Saturday. By then, soils will be saturated
with another round of heavy rainfall raising our flood potential to
some extent for our smaller creeks and tributaries. /PD
