WarningDesc:Coastal Flood Advisory, High Surf Advisory, Areal Flood Watch
WarningDate:2:30 PM PST on November 16, 2009
WarningSum:...Coastal Flood Advisory Now In Effect Until 3 Pm Pst Tuesday For
The South Washington Coast...
Warning Message:...High surf advisory now in effect until 6 PM PST Tuesday for
minor tidal overflow along low lying sections of the South
Washington coast...
The high surf advisory is now in effect until 6 PM PST Tuesday.
The coastal Flood Advisory is now in effect until 3 PM PST
Tuesday.
A series of disturbances from a strong Pacific storm system will
generate large seas and high winds through early Tuesday along the
South Washington coast. Meanwhile...published astronomical tides
will be near their monthly maximum due to the new moon. The
published tide for Toke Point Washington is expected to peak at
8.1 feet on Tuesday at 2 am...and at 10.1 feet at 1 PM on Tuesday.
Storm surge associated with the large developing offshore low
pressure system will likely be in the 1 to 3 foot range tonight
and Tuesday. Meanwhile...locally heavy rain from the Willapa Hills
will be channeling into Willapa Bay...further raising the water
level in the Bay.
As a result...minor tidal overflow is expected to occur along low
lying portions of the South Washington coast through Tuesday. The
greatest possibility of tidal overflow will be during the high
tides around noon today and 1 PM on Tuesday. The greatest
possibility of tidal overflow will be in and around the city of
Raymond...where similar circumstances caused minor flooding in
January of 2004.
During the storm...seas will climb to 23 to 27 feet with periods
around 11 seconds. These large seas will make for dangerous beach
conditions with waves pummeling the surf zone which will only be
exacerbated by the prominence of the enhanced lunar tidal cycle.
Seas have already reached 23 feet earlier today off the mouth of
the Columbia River...and will likely peak closer to the value of
27 ft tonight during the period of the strongest winds. Due to
the magnitude of the high tides...waves will travel much farther
up the beach than usual...creating a dangerous situation in which
extreme caution must be exercised. Large logs and other debris can
easily be tossed around by the force of these waves...even the
largest logs can roll easily on gently sloped beaches in ankle
deep water.
Precautionary/preparedness actions...
A coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.
A high surf advisory means that high surf will affect beaches in
the advisory area...producing rip currents and localized beach
erosion.
1211 PM PST Mon Nov 16 2009
...Flood Watch in effect through Tuesday evening...
The National Weather Service in Portland has issued a
* Flood Watch for portions of northwest Oregon and southwest
Washington...including the following areas...in northwest
Oregon...Coast Range of northwest Oregon...greater Portland
Metro area...lower Columbia and north Oregon coast. In
southwest Washington...Greater Vancouver area...I-5 corridor
in Cowlitz County...South Washington Cascade foothills...South
Washington coast and Willapa Hills.
* Monday afternoon through Tuesday evening
* due to heavy rain Monday afternoon through Tuesday morning.
Rainfall totals of 3 to 5 inches are possible in the Willapa
Hills...northwest Oregon Coast Range...and South Washington
Cascades.
* Rivers of most concern for minor flooding include the Willapa...
Naselle...and Grays rivers in southwest Washington...and the
Nehalem river in northwest Oregon. Some small stream and urban
flooding is also a possibility Monday night and Tuesday morning.
Precautionary/preparedness actions...
A Flood Watch means there is a potential for flooding based on
current forecasts.
Landslides and debris flows are possible during this flood event.
People...structures and roads located below steep slopes...in
canyons and near the mouths of canyons may be at serious risk
from rapidly moving landslides.
You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
The next update for this watch will be issued by 8 PM Monday.
WarningDesc:High Wind Warning
WarningDate:2:44 PM PST on November 16, 2009
WarningSum:...High Wind Warning Now In Effect Until 4 Am Pst Tuesday For
The South Washington And North Oregon Coasts...
Warning Message:The High Wind Warning is now in effect until 4 am PST Tuesday.
A prolonged period of strong south winds will continue through
tonight along the South Washington and north Oregon coasts.
South winds of 35 to 45 mph with gusts to near 70 mph have already
been reported earlier today. The winds will increase and reach
their peak tonight...with sustained south winds of 35 to 50
mph...and gusts up to 75 mph. However...on the open beaches and
headlands...sustained winds of 50 to 60 mph with gusts up to 85
mph are likely. The winds will then decrease early Tuesday morning
once a strong cold front moves onshore and the very strong
offshore low moves into British Columbia.
Precautionary/preparedness actions...
A High Wind Warning means a hazardous high wind event is expected
or occurring. Sustained wind speeds of at least 40 mph or gusts
of 58 mph or more can lead to property damage. Winds may gust
close to 90 mph along the immediate coastal headlands and beaches
tonight...and speeds near these values can cause power outages
and downed trees.
