* WHAT…Tidal overflow flooding.

* WHERE…North Oregon Coast.

* WHEN…Until 4 PM PST Friday.

* IMPACTS…Minor flooding, up to a half a foot above ground
level, especially during high tides is expected in the low

coastal rivers.

* ADDITIONAL DETAILS…This advisory may need to be extended as

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Coastal Flood 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.

Historically, similar conditions in the past have resulted in the
minor flooding of Highway 101 near Seaside, Nehalem, and/or
Tillamook. Water has covered parts of Frazier Rd, Miami Foley Rd
at milepost 1, as well as the intersection near Alderbrook and
Possetti road.
