.SYNOPSIS FOR NORTHERN CALIFORNIA WATERS...Southerly winds will
strengthen early Monday, especially north of Cape Mendocino with
gusts near 25 kts. Strong winds and steep, short period seas
will create conditions hazardous for small crafts in the northern
outer waters through Monday afternoon. Winds will diminish into
Tuesday but a westerly mid-period swell building over 10 feet by
early Tuesday will maintain moderately steep seas. A series of
frontal systems are expected to bring strong southerly winds and
steep seas late into the week.
