.SYNOPSIS...

Winds will quickly shift to the northwest behind the front tonight
with moderate offshore flow set to prevail from early Sunday
through Monday morning. The residual high swells and wave heights
from the south meeting these north winds will create very short
wave periods, resulting in steep seas after the frontal passage
for most of the day Sunday through Monday morning. Winds and seas
will gradually subside Monday afternoon and Tuesday as the surface
high settles over the area.
