The National Weather Service in Seattle has issued a Special Weather Statement for Western Washington lasting through the weekend into Monday. Friday and Friday night, there is a 100% chance of rain showers with a sustained wind growing to 17 mph. Saturday and Saturday night, the rains will become heavier and sustained winds will grow to 28-30 mph with gusts between 35-40 mph. Very Strong winds will affect the coastal areas on Sunday along with heavy rain throughout the County. The ocean swells are expected to grow to over 30 feet thru Monday. For Sunday, it is predicted that the coastal areas will be impacted by sustained Southwest winds between 30-40 mph. Gusts will be much higher, likely reaching near 50 mph! The daily high temperatures are expected to be in the low 50’s to upper 40’s. More information will become available as the event approaches.
The National Weather Service has issued a Special Weather Statement for the Southwest Washington Coast, indicating a increasing threat for coastal flooding Thursday through Saturday over this New Year’s Holiday.
Increasingly high astronomical tides, due to a full Moon, Southwest winds ranging from 20-33 MPH and very large coastal wave swells between 20-25 feet will combine to create minor to moderate tidal overflow conditions.
There will be two wind episodes that will impact the coastal areas. The first will begin Thursday afternoon which will arrive at the same time as one of the highest high tides of the year. The second Southwesterly wind episode will develop midday Friday (New Year’s Day) and continue through Saturday morning. A full Moon and extremely dangerous surf conditions with swells reaching 20-25 feet by Friday afternoon and lasting into the late night hours will add to the problems. The chance of tidal flooding is far greater over Friday into Saturday. Rain will continue to fall and the runoff into the rivers will add to the magnitude of the tidal and coastal flooding.
There is still uncertainty as to how much of an impact these conditions will create upon the area.
Grays Harbor County Emergency Management is asking all who venture onto the beaches for the area Clam digs over the New Year’s Holiday to exercise extreme caution. DO NOT TURN YOUR BACK TO THE SEA! Dangerous wave swells will be very unpredictable and can reach 20-25 feet with long runs up the beaches by the onrushing water. Waves will be powerful enough to sweep a person from the beach. Be alert for logs, debris and beach erosion, as this is common during high surf conditions.
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.
