 Coastal Flood Advisory, Areal Flood Watch  Statement as of 2:22 PM PST on December 21, 2014


... Coastal Flood Advisory remains in effect until 3 PM PST this
afternoon for the north and central Oregon coast and South
Washington coast...
... Coastal Flood Advisory in effect from 10 am to 4 PM PST
Monday for the north and central Oregon coast and South
Washington coast...

The National Weather Service in Portland has issued a coastal
Flood Advisory... which is in effect from 10 am to 4 PM PST
Monday. A coastal Flood Advisory remains in effect until 3 PM PST
this afternoon.

* Tides: the observed high tide this morning was observed around
11 ft at Toke Point and South Beach... and 11.5 ft at Astoria
with tidal anomalies of around 1.5 ft. The high tide tomorrow
afternoon around 1 PM is expected to be of a similar magnitude.

* River flows: flow on the coastal rivers remains high as a result
of abundant rainfall recieved yesterday. While flows will be
decreasing in the next 24 hours... they will remain high enough
for the midday high tide tomorrow to contribute to minor tidal
overflow.

* Timing: any minor tidal overflow will likely ease by 3 or 4 PM
Sunday as the tide continues to move out. However... minor tidal
overflow can again be expected during the high tide around 1 PM
Monday with impacts likely occuring between 10 am and 4 PM.

* Impacts: affected locations will include low lying areas near
bays and sloughs... Highway 101... and the lower reaches of
coastal rivers. Low lying areas near the city of Astoria... near
Highway 101 in Tillamook... and Highway 126 east of Florence were
impacted today and may also see minor tidal overflow on Monday.
These impacts should ease as the tide moves out again Monday
afternoon.


Precautionary/preparedness actions...

A coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

Area forecast discussion 
National Weather Service Portland or 
310 PM PST sun Dec 21 2014 


Synopsis...the remnants of an atmospheric river continue to bring 
moderate rain at times over the higher terrain of the Oregon Cascades 
and Coast Range. Precipitation will taper off tonight into early Monday 
as the baroclinic zone stalls and weakens over south-central Oregon. 
The heavy rainfall over the weekend caused numerous rivers to reach 
flood stage. River flooding impacts will continue tonight and into 
early next week. The stalled baroclinic zone over central Oregon will 
lift north as a weak warm front later Monday and Monday night. Then a 
stronger frontal system will bring a quick shot of precipitation Tuesday 
night into Wednesday. This system will usher in a colder air mass and bring 
potential for some accumulating snow to the Cascade passes later Wednesday 
into Thursday. A quiet weather period appears to be in store late next 
week as upper level ridging builds over the Pacific northwest. Another system 
may bring bring precipitation at some point over the weekend. 


&& 


Short term...tonight through Wednesday... 
the heavy rainfall over the weekend caused numerous rivers to reach 
flood stage. River flooding impacts will continue tonight and into 
early next week. See the hydrology section below for more details. 


The remnants of the atmospheric river continue to bring moderate rain 
at times over the higher terrain of the Oregon Cascades and Coast 
Range this afternoon. However the heaviest precipitation has long since 
ended...as the orographic forcing has weakened and available moisture 
has begun to decrease. But batches of enhanced moisture have been 
moving onshore and enhancing the precipitation periodically today. The 
rainfall will taper off even more tonight into early Monday morning as 
upper level ridging begins to build over the Pacific northwest and further cuts 
off the sub-tropical moisture tap that has been feeding into this 
system. A cold front is slowly pushing in from the north today...and 
will continue to move slowly south tonight...eventually stalling and 
weakening over south-central Oregon early Monday. More organized 
precipitation may linger into Monday morning over the Lane County 
Cascades depending on how far south the baroclinic zone stalls. 
Cooler air will be filtering in from the north tonight behind the 
cold front...which should allow snow levels to fall back down to near 
the Cascade passes overnight. There is the potential for a few inches 
of snowfall at some of the higher north Oregon passes through early 
Monday...but do not expect we will be near advisory accumulations. 


Agreement amongst the forecast models is increasing that there will be 
another period of light precipitation late Monday into Tuesday...as a shortwave 
trough offshore reactivates the stalled baroclinic zone and lifts it 
northward through the region again as a weak warm front. Increased 
forecast probability of precipitation during this time period...but quantitative precipitation forecast appears to fairly 
limited. Another shortwave is modeled to push the boundary through as 
a fairly sharp cold front on Wednesday. It appears that there will be a 
burst of fairly heavy precipitation with this system...along with 
dropping snow levels. The timing is somewhat uncertain at this time. 
The 12z European model (ecmwf) model brings precipitation onto the coast beginning Tuesday 
afternoon and spreads inland overnight into Wednesday morning. The 12z GFS 
and NAM are about 6 hours slower...bringing most of the precipitation through 
during the day Wednesday. This system should bring decent accumulating 
snowfall to the Cascades down to the passes. Pyle 


&& 


Long term...Wednesday night through Sunday... 
expect lingering showers Wednesday night and Thursday behind the departing 
frontal passage earlier Wednesday. Expect additional light snowfall 
accumulations in the Cascades during this time. The snow level should 
be below the passes...possibly even into the Cascade foothills. Going 
into Thursday night and Friday...there are slight differences between GFS and 
European model (ecmwf) models. The GFS develops ridging over the Pacific northwest and keeps US 
dry through the rest of the week. The European model (ecmwf) has a weaker ridge and 
keeps it further offshore...allowing light showers to remain over the 
region into Friday. Forecast uncertainty increases further next weekend. The 
GFS is dropping a low pressure system into the interior Pacific northwest and brings 
a colder air mass. Meanwhile the ewmcw is closing the low off and 
keeping it offshore...which would result in a wetter and milder 
weekend. Will avoid adding to much detail to the forecast during this 
time period...and keep a chance of probability of precipitation through the weekend. Pyle 


&& 


Hydrology...moderate rain continues at times this afternoon. The 
rain will taper off tonight into early Monday. Numerous flood warnings 
are already in effect...but all local rivers are expected to remain 
below major flood stage. Coastal rivers have crested and most will 
fall below flood stage this afternoon and evening. Willamette 
tributaries will continue to rise and any flooding will generally 
begin later today. Flooding along the mainstem Willamette looks 
unlikely at this point. See the latest warnings and flood statements 
at www.Weather.Gov/Portland (lower case) for additional details. 
Bowen 


Some minor tidal overflow was again observed this afternoon as a high 
astronomical tide combined with higher flows on the coastal 
rivers. Low lying coastal areas near willapabay...Astoria...Tillamook 
Bay...Depoe Bay...Waldport...and Florence...along with coastal 
stretches of Highway 101 near the coast will likely see some minor 
issues again. With similar tidal values tomorrow afternoon...it is 
expected that at least some of these locations will again see some 
minor overflow issues. Cullen 


&& 


Aviation...moderate onshore flow continues today with abundant 
middle and high clouds and some rain showers remaining. VFR flight 
conditions for most locations with some pockets of local 
MVFR...particularly along the coast and in the south Willamette 
Valley. Rain generally continues to decrease with some lowering 
ceilings tonight...trending towards increasing areas of MVFR with 
local areas of IFR possible overnight. 


Kpdx and approaches...mostly VFR through his evening with a few 
lingering showers possible. Expect ceilings to lower a bit overnight 
with MVFR conditions possible after 06z. Cullen 


&& 


Marine...W-SW winds over the waters remain around 15 to 20 knots 
this afternoon. Winds will continue to ease and remain light and 
become more west-northwest overnight through Monday. Meanwhile...seas continue 
to run between 13 feet and 15 feet and will continue to slowly subside 
but remain around 11 feet or 12 feet through much of the week. An 
approaching frontal system will turn winds southerly again late 
Monday or early Tuesday with the potential for Small Craft Advisory level 
winds Tuesday and Wednesday and increase seas back to around 15 feet. Seas 
likely finally drop below 10 feet by later Thursday or early Friday. Cullen
