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.
