South Bend, Washington – A high surf advisory has been issued by the National Weather Service (NWS) and is in effect until 10:00 a.m. Tuesday for the south Washington Coast. A strong Pacific storm will generate large seas and high winds through early Tuesday. Astronomical tides will be near their monthly maximum due to the new moon. Storm surge associated with the large developing offshore low pressure system will likely be in the one to three foot range tonight and Tuesday. Locally, heavy rain from the Willapa Hills will be channeling into Willapa Bay further raising the level in the bay.
During the storm, 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.

The NWS also issued a coastal flood advisory in effect until noon Tuesday. Minor tidal overflow is expected to occur along low lying portions of the south Washington Coast through Tuesday. During the high tides around noon today and 1:00 p.m. on Tuesday, the greatest possibility of tidal overflow will be in and around the City of Raymond.
A high surf advisory means that high surf will affect beaches in the advisory area producing rip currents and localized beach erosion. A coastal flood advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore.
