The National Weather Service in Portland has issued a Coastal Flood Advisory, which is in effect from noon to 3 PM PST Monday.
For the North Oregon Coast, Tillamook County Emergency Management said one of the more susceptible areas for flooding is Fraser Road along the Tillamook River. The expected weather severity is minimal, but the the alert indicated that preparatory action should be taken.
The advisory for minor tidal overflow indicates that coastal and inland flooding of low-lying areas is expected due to elevated river levels combined with high astronomical tides. Property damage can occur, but is usually localized. Low-lying roads may be closed due to high water.
Overflow flooding for the South Washington coast is most likely to occur in low-lying areas near bays and sloughs, Highways 6 and 101, the towns of Raymond and South Beach and lower reaches of coastal rivers.
The total tide at Toke Point is forecast to be 11.5 feet Sunday afternoon and then 11.4 feet Monday afternoon. The total tide at Astoria is forecast to be 10.3 feet Sunday and then 10.1 feet Monday.
