A challenging weather week lies ahead for residents and businesses around the western and southwest-facing slopes of the Olympic Mountains, our northern islands from Whidbey Island to the San Juans, and western Skagit County, Western Whatcom County, and Admiralty Inlet. These areas will receive cumulative rainfall over the series of storms headed in for the next seven days. These areas are also expected to receive the strongest wind gusts and have the most persistent wind each day.
A wind advisory begins at 1 p.m. today for the coastline of Washington, the north interior, including all the islands, and parts of Whatcom, Skagit, Northwest Snohomish County, and Admiralty Inlet, impacting parts of the Quimper Peninsula. Sustained wind will be from the southeast at 20-30mph, with wind gusts up to 50mph. The wind advisory expires at 7 p.m.
If you live in the city of Seattle, you might only notice a cloudy, rainy day today. Many of us will see rain at times, but the heaviest rain is going to fall in the Olympic Mountains. The inland areas will benefit from the rain shadow of the Olympic Mountains; they will be prevented from getting the significant rain expected.
Today’s weather system will bring a windy and rainy day at the coast and over the Olympics, where 1 to 3 inches of rain will be falling and running down into the Skokomish River. A flood watch is in place from this evening through Wednesday evening. This will impact cities like Shelton, and Elma. Minor flooding is expected on the Skokomish River.
The Washington Coast is currently under a High Surf Advisory and a Coastal Flood Warning. The surf zone is a dangerous place to be today, with seas building to 20 feet and a risk of being swept away by unexpected waves or waves holding unseen logs and debris. It is a period of astronomically high tides, which may cause minor flooding.
