What forecasters said that day

The local office's own words before this river flood warning 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 river flood warning went out at Jan 10, 3:58 AM PST, 10 hours 32 minutes earlier.

Area forecast discussion, Jan 10, 3:58 AM PST, 10 hours 32 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
358 AM PST Tue Jan 10 2017

.SYNOPSIS...Strong winds and widespread rainfall will impact
northwest California today. Periods of heavy rain will cause
rapid rises on rivers as well as flood concerns in urban areas and
small streams. There will also be a chance for thunderstorms late
this afternoon into evening as the front passes overhead. Showers
will taper on Wednesday before building high pressure brings
mostly dry weather late in the work week.

&&

.DISCUSSION...Stratiform precipitation will increase region-wide
as the next plume of moisture takes aim at northern California today.
Rainfall totals still look on track for 1 to 3 inches across the
region with 4 to 5 inches possible in terrain favorable to
orographic effects. Impactful snow is not expected with this system
as snow levels will rise above 5000 feet this afternoon. Area rivers
will rapidly rise again and bring small stream and urban flood
concerns. Ponding water in roadways and mud/rock slides will be
possible during periods of heavy rain. In addition to the heavy
rain, strong winds will impact much of the coast and near interior
as a southerly jet sets up along the coast. 850 mb winds are
forecast to reach over 70 mph. Ridges above 2000 feet may see gusts
of this magnitude. Coastal areas may observe gusts up to 45 mph but
coastal Del Norte may see higher gusts around 50 to 60 mph.

There will be a chance for thunderstorms late this afternoon and
evening as a shortwave trough advances over the region. The
environment looks favorable for storm development over the waters and
over land with negative Lifted Indices and several hundred joules of
MUCAPE forecast. The storm prediction center also circled the
northwest California coast and near interior under marginal risk
indicating that deep layer shear could help bring convective cells
to approach severe criteria but weaken as they move onshore.

Widespread rain will shift out of the area as the cold front tracks
southeastward later tonight. Convective showers should persist
through Wednesday as the upper trough ushers in a cold air pool.
500mb temperatures will drop down -30+ deg C by Wednesday. Although
there will be less MUCAPE than expected today, there still looks to
be a slight chance for thunderstorms with small hail as the frigid
air aloft will generate sufficient instability. Snow levels will
subsequently drop to around 2000 feet on Wednesday but convective
showers look to be too sparse to bring impactful snow, however,
snow flurries will be possible.

Building high pressure will bring a break in the wet weather for
Thursday and Friday. The pattern over the weekend looks less active
with long range models backing off on a system that was going to
bring rain. This could mean mostly dry weather will persist through
the weekend with possible enhanced offshore flow as a closed low
dives to the south. /KML

&&

.AVIATION...A strong frontal wave will move east across the region
today and tonight. As this takes place, a warm front will lift north
along the coast during the morning. Strong southerly winds are
forecast to develop in the wake of the front, with winds locally
gusting in excess of 40 kt. In addition, widespread moderate to
heavy rain is probable late this morning into early evening along
with associated MVFR to IFR conditions. By tonight, the environment
will become increasingly convective with stratiform rain
transitioning to showers. Winds will also weaken overnight...though
locally gusty winds will be possible with any thunderstorms that
move onshore.

&&

.MARINE...A strong frontal wave will move east across the northern
waters through this afternoon, and then move onshore over coastal
Oregon tonight. As this occurs, a warm front will lift north this
morning, with south-southwesterly gale force winds gusting to 45 kt
developing in its wake over all marine zones. Steep seas to 16 feet
are also forecast to develop coincident with the onset of gales. In
addition, the environment is forecast to become favorable for
isolated thunderstorms today and tonight. A few storms could be
strong, and pose a threat for locally gusty winds to 50-60 kt, as
well as waterspouts.

By late tonight, winds are forecast to weaken significantly as they
veer to westerly. By midweek, winds will become northerly, and may
approach small craft speeds offshore from Cape Mendocino.

&&

.HIGH ASTRONOMICAL TIDES...High astronomical tides in conjunction
with prolonged southerly winds will bring some coastal flooding to
low areas along the coast at high tide this morning. The tidal
anomaly has been greater than one foot which will bring the
waters to around 9.5 feet today at the north spit tide gauge. 16
foot breakers could exacerbate coastal flooding this morning
especially with tides this high, however, breakers closer to 20
feet would be more favorable for sea water to impact highway 101
at spots close to the beach. Coastal flooding means salt water may
inundate areas that may normally remain dry during high tides.
High tides are predicted to be quite large the next few days but
northerly winds are forecast to develop offshore by Wednesday
which may subdue the tidal anomaly. Stay tuned this week for
coastal flood concerns.

&&

.HYDROLOGY...Widespread rain today will bring rapid rises causing
multiple mainstem rivers to crest in flood and monitor stages late
tonight and early Wednesday morning. The expected break in the wet
weather pattern will allow rivers to recede and remain below flood
and monitor levels late this week.
