I am about a days sail or motor east of the Golden Gate Bridge leading out of San Franciso Bay to the Pacific Ocean. If a huge storm / hurricane / tsunami / flood is predicted, it is not likely I can sail out of the narrow Delta waterways and up or down the California coastline far and fast enough to avoid such things. At this point in time, all I can do is batten down the hatches, put out extra mooring lines to the dock, and deploy extra bumpers.

My big decision is whether or not to bug out in my vehicle and abandon the boat to its fate. I am pondering what factors and data I need to make that decision, which is the genesis of this thread.
