Broad surface high pressure will gradually weaken as a thermal trough builds along the Oregon coast and a frontal system moves southward from the Gulf of Alaska. This system will make its way to western Washington Tuesday night into early Wednesday, but will largely fall apart by the time it arrives. The next, more substantial, low pressure system will move through the region on Thursday. Winds will likely pick up on Thursday with this system but the exact details are uncertain with evolution and track of this system. A push of westerlies are expected into the Central and East Entrance to the Strait of Juan de Fuca beginning Tuesday afternoon, for which a Small Craft Advisory has been issued. Winds will ease below advisory criteria into Wednesday but will remain breezy through Wednesday evening. Seas are expected to remain around 4 to 6 ft through the rest of this week.
