California waters-
Inner waters from  60 nm to 150 nm offshore.
Outer waters from 150 nm to 250 nm offshore.

Conditions given represent the highest within that period.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

.SYNOPSIS FOR CALIFORNIA WATERS...A stationary front draped
across the northern half of the waters will begin lifting N as a
warm front today as low pressure develops just W of the northern
waters. As that low moves quickly NE and then N away from the
area, a cold front extending S from the low will move SE across
the northern and central waters tonight and Fri, reaching the
southern waters Fri night. On Sat, a new weaker area of low
pressure will develop W of the waters. It will move E into the
northern waters Sat night into Sun before weakening into a trough
Sun night. The low will drag a cold front across the central and
southern waters Sun night through Mon night. An additional weak
and broad area of troughing will extend S from broad low pressure
N of the area and will move E across the northern waters Mon and
Mon night.
