* IMPACTS...There is a high risk for flooding of sea water over
vulnerable low-lying coastal areas, especially around the time
of high tide. This includes significant flooding of coastal
beaches, walkways and roads, and potentially damaging some
structures. Significant beach erosion is expected. Powerful
waves and strong rip currents will pose an exceptional risk of
ocean drowning and damage to coastal structures like piers and
jetties. Large breaking waves can cause injury, wash people
off beaches and rocks, and capsize small boats near shore.
Remain far away from the water's edge.

will create an extended period of large surf into next week,
with the potential for WARNING level surf again late Sunday

impacts will be west- northwest facing beaches, with
widespread flooding likely at low lying areas such as at
Oceano Dunes. Breaking waves may impact the Cayucos and Pismo
Beach piers as well as the Morro Bay Harbor entrance.

What to do: Stay off of beaches and coastal walkways, roads, and structures. Do NOT drive around barricades or through water of unknown depth. Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other water side infrastructure.
