Special Weather Advisories: High Tides And Rain, Then A Cold Front


Minor Tidal overflow flooding is expected today until 2pm, with the highest tides occurring near 11am. Total tide is expected to be near 11 feet. Minor flooding, up to one foot above ground level, during high tides is expected in the low lying areas near bays, sloughs, and the lower reaches of the coastal rivers. A Coastal Flood Advisory means that tidal overflow flooding is expected. Coastal residents in the warned area should be alert for rising water, and take appropriate action to protect life and property. It is also possible there could be high water on the roadways. Drive with caution.


Rain, is in the forecast today mainly after 7am. The rain could be heavy at times. High near 50. Very windy, with a south southwest wind 18 to 23 mph increasing to 28 to 33 mph in the afternoon. Winds could gust as high as 45 mph. Chance of precipitation is 100%. New precipitation amounts between three quarters and one inch possible.


A pair of strong cold fronts will move across the Pacific Northwest through the weekend, and the pattern will turn significantly colder next week. These cold fronts will likely bring heavy snow to the Cascades. Snow levels are expected to remain well above the valley floors through Sunday.The colder air is expected to move into southwest Washington and northwest Oregon early next week, potentially cold enough to bring snow levels down to the valley floor.


An increasing number of forecast models are suggesting additional disturbances from the Gulf of Alaska which would spread moisture into that colder air.This will raise the chance for snow down to the lowest elevations next week.While accumulations, distribution, and/or timing of snow remain uncertain, confidence is increasing in the overall threat of snow next week, even for the lowest elevations. Now is a good time to make sure you are prepared in the event that all of the necessary ingredients come together for a significant snow event next week.
