1108 PM PDT Thu Oct 9 2025

.SYNOPSIS FOR NORTHERN CALIFORNIA WATERS...Southerly to southeasterly
winds will increase preceding an approaching frontal system.
Strong wind gusts from 35 to 45 kt associated with isolated to
scattered thunderstorms will be possible (20% chance) early
Friday morning. This threat for thunderstorms and strong gusty
erratic winds will persist through the day on Friday as a decaying
low pressure system slowly tracks into the northern waters. Gusty
shower activity may continue overnight Friday and possibly into
Saturday morning, before more stable conditions and northerly
winds build by Sunday. A northwest swell around 4 to 6 ft at 10
seconds Friday will likely build to 5 to 7 ft on Sunday.
