Coastal Waters Forecast for Washington
National Weather Service Seattle WA
224 AM PDT Mon Sep 30 2024

Inland waters of western Washington and the northern and central
Washington coastal waters including the Olympic Coast National
Marine Sanctuary

PZZ100-302230-
224 AM PDT Mon Sep 30 2024

.SYNOPSIS FOR THE NORTHERN AND CENTRAL WASHINGTON COASTAL AND
INLAND WATERS...Thermally induced low pressure expanding
northward along the Oregon coast today will turn the flow weakly
offshore. Onshore flow resumes Tuesday as a weak front dissipates
over the coastal waters. Northerly flow returns on Thursday as
another surface ridge builds into southern British Columbia.
Hazardous double digit seas are expected to reach the coastal
waters later Tuesday into Wednesday as the result of a deep
surface low passing well north of the area across the Gulf of
Alaska.
