Coastal Hazard Message
National Weather Service Portland OR
558 AM PST Wed Jan 17 2018

...SIGNIFICANT SURF AND BEACH EROSION LIKELY TONIGHT THROUGH
THURSDAY...

.A 25 to 30 foot swell train will reach the coast late tonight
and peak around mid-day Thursday close to high tide. This event
appears to be similar to, or slightly stronger, than the December
2015 event where waves ran much higher on the beaches and impacted
numerous low lying structures adjacent to beaches and harbors.

...COASTAL FLOOD WARNING REMAINS IN EFFECT FROM MIDNIGHT TONIGHT
TO MIDNIGHT PST THURSDAY NIGHT...

* SEAS...Westerly swell of 27 to 32 feet with dominant period
  17-19 seconds.

* TIDES...High tide is forecast to be 8.5-9.5 feet between
  midnight and 2 AM Thursday and 9.5-10.5 feet between noon and 2
  PM Thursday.

* HIGH SURF IMPACTS...Breaking waves of 35-45 feet and parallel to
  the coastline will send water much further up beaches and
  jetties than normal. Structures and roads located immediately at
  beach level will potentially be flooded or impacted by debris.
  Many cove access beaches, jetties, and rocky out croppings will
  be covered by deep water.

* COASTAL FLOODING IMPACTS...Higher than normal tides and large
  seas will likely result in beach erosion and some flooding of
  low lying locations along the coast including areas around
  Willapa Bay, Seaside, Nehalem, Tillamook and Florence,
  particularly during the high tide midday Thursday.

* RIVER FLOWS...Tidal overflow flooding of inland areas is
  possible but low river flows may limit impacts.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Warning means that flooding is occurring or
imminent. Coastal residents in the warned area should be alert
for rising water, and take appropriate action to protect life and
property. Visitors should remain off beaches and avoid narrow
access areas where escape routes could be cut off by rising water.
