Severe Weather Alert Descriptions

 Special Statement  Statement as of 2:35 PM PDT on October 21, 2014


... Wet and windy week ahead for southwest Washington and northwest
Oregon...

A strong and wet Pacific storm system will bring periods of heavy
rain to southwest Washington and northwest Oregon tonight through
Thursday morning. Strong winds are also expected along the coastal
headlands and higher terrain of the Coast Range tonight into
Wednesday morning.

South winds are increasing along the coast this afternoon as the
front approaches the Pacific northwest coastal waters. Winds will
be especially strong along the beaches and headlands... where gusts
of 60 to 70 mph are expected at times tonight through early
Wednesday. Coastal communities may see gusts upwards of 50 mph as
the front slowly sags down the coast later tonight into Wednesday
morning.

South winds will also increase later tonight into Wednesday for
the inland valleys and main Metro areas... where gusts of 25 to 35
mph are possible. Many trees still have a fair amount of leaves
on them... which could cause more limbs to break than is often the
case with such winds. As a result... some minor power outages are
possible as the gusty winds develop.

The frontal system has tapped into sub-tropical moisture which
will enhance rainfall near the front as it slowly moves through
the area tonight through early Thursday. Rain will be heavy at
times along the coast and in the higher terrain... and possibly in
the inland valleys as well.

Rainfall totals of 1 to 2 inches are expected in the inland
valleys by Thursday afternoon. Coastal locations are expected to
receive 2 to 4 inches of rain... and 3 to 6 inches of rain are
forecast for most of the Coast Range and Cascades.

Minor urban flooding is possible due to Autumn Leaves clogging
storm drains... especially Wednesday into Wednesday night when the
heaviest rain is expected. Additionally... there is a possibility
of minor flooding on a couple of fast responding small streams
and rivers due to the heavy rain. Burn scar areas from recent
wildfires in the Cascades may also be subject to debris flows or
mudslides. All of this will be monitored closely over the coming
days.

After a lull on Thursday... another strong system may affect part
of the area Friday into this weekend. Details on this system are
still quite uncertain... but it appears southwest Washington and
northwest Oregon is in for a fairly extended period of wet and
unsettled Fall weather.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
906 PM PDT Tuesday Oct 21 2014 


Synopsis...a strong frontal system continued to intensify off the 
coast this evening and was moving into western Washington and 
beginning to move into northwest Oregon this evening. This front will 
bring strong winds to the coast tonight and Wednesday morning...with 
breezy conditions. This system will be a slow mover...producing heavy 
rain along the north coastal areas later tonight...spreading inland 
mainly on Wednesday...and lingering in the southern areas such as 
Lane County Wednesday night. Another wet and potentially quite windy 
front not only for the coast but possibly inland is expected by the 
weekend. 
&& 


Short term...tonight through Friday...a strong frontal system was 
intensifying off the Washington and Oregon coasts this evening... 
with satellite imagery indicating a decent surface low developing 
along the front. The occluded or warm front is moving onto the 
coast...with the strongest winds along the coast in the north along 
beaches and headlands. Winds have briefly lightened along the central 
Oregon coast...but should pick up later tonight through Wednesday 
morning as the developing low moves northeast and onshore and the 
associated cold front slowly sags south. The current High Wind 
Warning for the coast looks good and will be continued. Look for some 
breezy conditions as well tonight and Wednesday morning along the 
Interstate 5 corridor especially from about Portland northward. 


The main impact from this frontal system will be the heavy rain. The 
initial focus will be into western Washington...but begin to spread 
into our north coastal areas late tonight and Wednesday morning... 
and extend from the South Washington Cascades to the central Oregon 
coast Wednesday afternoon. The main band of precipitation will 
continue to move slowly south through Lane County Wednesday night 
into early Thursday as precipitation rates east in the north. At this 
point we think the rivers will have sharp rises but probably not 
flood...but if the front stalls a bit or rainfall rates are a bit 
heavier than forecast than we may get a couple of river close to 
flood stage. However...the heavy rain will likely lead to areas of 
Urban and Small Stream flooding as smaller creeks have trouble 
containing the runoff and storm drains get blocked by leaves and 
cause some local flooding. 


Thursday still looks somewhat wet under southwest flow aloft but the 
main front will be south of our area and rainfall accumulations will 
be considerably less than Wednesday as the precipitation is more 
showery. 


There is another strong and wet storm expected to lift north along 
the coast and impact northwest Oregon and southwest Washington 
significantly on Friday into the early part of the weekend. While 
there are some differences amongst the models...this system is 
looking quite wet again...with a surface low that will probably bring 
more widespread high winds to the coast and a significant number of 
tracks suggest possibly very windy conditions inland as well. Autumn 
is kicking into full gear with a bang. Tolleson 


Long term...Friday night through Monday...forecast models continue 
to keep the region in an active weather pattern through the weekend 
as frontal systems move through every other. While some subtle 
differences remain...models remain in reasonable agreement that 
another potent low pressure system will develop offshore bringing a 
round of gusty winds and potential heavy rainfall for late Friday 
into Saturday. Showers likely linger for Sunday before another 
frontal system approaches on Monday into Tuesday for more rainfall. 
While some question remains as to how the low pressure systems will 
evolve and track...and just how strong they will be...it seems 
likely that we will remain in an active pattern with wet weather at 
times through early next week.Cullen 


&& 


Aviation...warm front offshore will move inland overnight with 
following cold front to the coast late tonight and inland Wednesday. VFR 
should prevail inland through 15z-20z Wednesday with increasing chances for 
MVFR as heavier rain moves in with the front. MVFR will probably be 
widespread after 00z Thursday. For coastal areas...a mix of VFR and MVFR 
to start but as the warm front nears the conditions will deteriorate 
with MVFR and IFR likely. Strong low level winds will also be a 
concern with model sounding showing south wind 45 to 50 knots as low as 
1000 feet. 


Kpdx and approaches...VFR prevailing through 18z Wednesday and perhaps 
until 00z Thursday. But after 18z Wednesday guidance indicating increasing 
chances for MVFR conditions to develop as the cold front nears then 
moves through in the evening. Southeast winds are expected to switch 
to southerly winds to increase overnight. Low level windshear not a 
high concern at this point but should the east to southeast surface 
wind hold...areas toward the Columbia River gorge could experience 
low level wind shear Wednesday morning. 
&& 


Marine...a warm front working its way to the coast. Winds have 
turned a little more to the southeast this evening but will return to south 
once the warm front lifts north overnight. 


High end gale force gusts near 45 knots at times tonight...with storm 
force gusts of 50 to 55 knots possible over the near shore waters due to 
coastal jet enhancement. Winds will begin to diminish by middle to late 
morning tomorrow after the cold front pushes onshore. Update with 00z 
model run appears peak wind at the coast should be between 3 and 5 am 
Wednesday. 


Seas are currently sitting in the 13 to 15 feet range...but expect them 
to increase significantly tonight in response to the strengthening 
southerly winds. Seas may approach 20 feet overnight during the period 
of highest winds. Seas will gradually decrease during the day 
tomorrow as the winds die down...but expect they will remain in the 
middle teens through much of the day. 


There will be a bit of a break Thursday and part of Friday as weaker 
troughs move through. But another potentially strong front is being 
modeled for later Friday into Sat. There is quite a bit of uncertainty 
in this system at this time..so will keep previous forecast as is and 
wait for remainder of 00z model runs to arrive. But it appears that 
another solid gale with seas into the middle to upper teens is a strong 
possibility. Pyle/mh
