South Bend, Washington – The National Weather Service, Portland Office issued a special weather statement, regarding the potential for wind and coastal storm surge later in the week.
Increasingly high astronomical tides combined with moderate southerly winds Thursday through Saturday may result in the potential for coastal flooding toward the end of this week. The first episode of wind will occur midday Thursday which coincides with one of the highest high tides of the year.
A second wind event will develop midday Friday also near the time of high tide, continuing through Saturday morning. The most susceptible time for tidal overflow or coastal flooding will be midday Friday and again midday Saturday.
At Toke Point near Willapa Bay astronomical high tides of 11.1 ft will occur at the midday tides Thursday and Friday. Water Levels over 11 ft create minor tidal overflows while 14.5 ft is the threshold for more widespread coastal flooding. The magnitude of tidal anomaly is still uncertain.
In addition, rain showers may be mixed with snow in the coast range, with snow levels rising above 3000 feet in the afternoon.
