Synopsis for the far Southern CA coast

At 1 AM, a 1017 mb high was 600 nautical miles west of Morro Bay and a 1007 mb low was over Death Valley. Weak to moderate onshore flow will continue through Saturday. As a storm system moves through the coastal waters this weekend, shifting winds and seas are likely to increase Saturday night into Sunday morning, possibly to hazardous levels. There is also a slight chance of thunderstorms Saturday night and Sunday morning. Winds decrease late Sunday. Seas diminish on Monday as weak offshore flow develops.
