A weak surface low over the interior waters will fill and shift eastward on Tuesday as a weak surface ridge builds over the coastal and interior waters. The ridge will shift eastward Tuesday evening as a vigorous frontal system moves into the offshore waters. A frontal triple point will come onshore over Vancouver Island while the trailing cold front sweeps onshore into Western Washington late Wednesday morning. There is a 70-90% probability of gale force wind gusts just ahead of the front over portions of the coastal waters and the east entrance to the strait. Gale watches are in effect for those areas. A gradually weakening surface low will track southeastward across the offshore waters Wednesday night into Thursday. Weak surface ridging will rebuild over the waters early in the coming weekend. Coastal seas will build back into hazardous double digits Tuesday night into Wednesday and likely remain above the 10 foot threshold into early Friday. 27 (Issued: 805 PM PDT Mon Oct 28 2024 by NOAA)
