.SYNOPSIS FOR THE SOUTHERN OREGON COASTAL WATERS...South gales
and very steep wind-driven seas are expected today as a cold
front moves through the waters. Winds will diminish after the

through Friday due to building long-period west swell. Gusty north
winds are expected to develop early next week as a thermal trough
strengthens along the coastline.
