.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A warm front moving
E over the area will quickly be followed by a cold front moving
E across the waters later today into tonight before moving inland
Sun. The associated low pressure system will track E tonight,
remaining N of the waters and quickly weakening. However,
significant swell generated by this system will move E into the
waters tonight. The swell will then gradually diminish Sun and
Sun night. A high pressure ridge will build NE across the waters
Sun night through Mon. Another weaker cold front will move E and
then SE across the waters Mon night before dissipating on Tue.
High pressure ridging will follow the front on Tue, before
quickly moving inland ahead of the next cold front, passing over
the waters Tue night into Wed. Yet another stronger cold front is
expected to move E across the area late Wed night.
