.SYNOPSIS...Isolated light showers will continue to taper off
during the early morning hours. Northwest gale-force winds (35 to
40 knots) will slacken during the morning, but we will hang on to
hazardous marine conditions through Monday as breezes and seas
will be slow to come down. North to northeast breezes will slacken
further on Tuesday, becoming gentle to moderate. Near the end of
the week, another cold front may push through the area, and could
bring another push of freshening breezes and building seas.
