Marine Weather and Tide Forecast for Ocean Shores, WA

SHORT TERM /TODAY THROUGH TUESDAY/
A weak front will brush through western WA this morning with isolated to scattered showers. High pressure will build inland this afternoon for drier conditions. Expect partly sunny conditions with highs in the upper 40s to lower 50s.

High pressure and offshore flow will prevail on Monday for dry weather. Morning lows will be a little cooler with lows in the 30s, and temps near freezing around the south sound.

A stronger and wetter Pacific frontal system will impact the area on Tuesday. This system is tied to a deep low spinning offshore that will shift north of Haida Gwaii. The main threat will be gusty south winds, primarily coast and north part, where probabilities of gusts exceeding 45 mph are the highest. Up in the mountains, snow levels are lowest over the northern Cascades where a few inches of snow will fall. Snow levels will be rising over 5,000 ft in the central Cascades thus minimizing impacts to I-90 and US 2. Rivers will see small rises but additional flooding is not anticipated. 33

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
We remain under moderate onshore flow on Wednesday with high pressure offshore and deep low pressure to our north. Snow levels are lower, around 2,500 ft, with snow in the Cascades and passes. Showers with a convergence zone may enhance snow amounts near Stevens Pass. High pressure shifts inland Thursday, Friday, Saturday for drier weather across the board. Expect warner highs in the interior Friday and Saturday with lower 60s possible. Dry offshore flow will keeps lows cool and in the 30s. 33

AVIATION
Zonal flow will continue to prevail across western Washington today. A weak and mostly dry front is moving across the area early this morning. This will bring increased ceilings this morning, but conditions are expected to remain mostly VFR.
Chances for MVFR cigs this morning remain below 15-25% across the area terminals. Ceilings will lift and scatter through the late morning, with high clouds dominating the skies through the remainder of the day and tonight.

Winds this morning are mostly light and variable, through remain south/southeasterly through Puget Sound area. Winds are expected to continue to ease through the morning, switching to light northerly at around 19-20Z early this afternoon, increasing to around 8 to 12 kt by 00Z Mon and remain like so through much of tonight.

KSEA...VFR conditions are expected to prevail through the TAF period. CIGs will gradually redevelop this morning as a dry front moves through the area. This will be relatively short lived as clouds scatter by this afternoon and high clouds prevail through the remainder of the period. S winds will gradually decrease through the morning, turning N by 20Z, and increasing to 8 to 12 kt after 00Z Mon through the end of the period.

MARINE
A weak and mostly dry front is currently traversing the coastal waters early this morning. Winds across the far northern portions of the coastal waters, as well as the west entrance to the Strait of Juan de Fuca remain a bit elevated with gusts up to 20-23 kt, but these winds should ease through the morning. Otherwise, high pressure will continue to dominate across the area through Monday. Seas will remain in the 5-8 ft range through Monday as well. The focus then turns towards Tuesday as a strong low pressure system moves into the region from the southwest. Uncertainty remains to the exact track of the system, but stronger winds and increasing seas are likely across the coastal waters. The NBM indicates that at least Small Craft Advisory winds are very likely (>90%) across all the coastal and interior waters, with 40- 60% chance of gale force winds across the coastal waters on Tuesday. GEFS ensemble guidance continues to show a 50-70% chance of seas exceeding 20 ft Tuesday night into early Wednesday.
