If a crazy freak storm like this happens, I have a foolproof plan.
1. Load all computers and canned food into V8 station wagon.
2. Drive across the street to the liquor store, break the windows, and raid the entire place, by force if needed (I live in a residential area, but by a loophole, there is a small 1 story commercial liquor store. People have offered the old man who owns it hundreds of thousands for it so they can build a condo or something, but he refuses). Steal all hard liquor, beer is too cheap to bother with.
3. Drive to my job at the end of the peninsula I live on, US Sailing Center of Long Beach. Unload all alcohol, food, and electronics into the largest powerboat we have, a Grand Banks Committee Boat, using our loading ramp. I would be able to get to the sailing center before anyone else, living within 1 minute driving distance, so I would be the first person with access to the facilities. To prevent other cars from being able to enter the peninsula, I would quickly push all our trailers into the two lane road right outside that leads to the opening, then sever our fueling line from our underground fuel storage area, and throw the severed end into the street. Turn on pump, and ignite the resulting pool, it would buy me a river of fire for at least 15 minutes before draining. I do not need a load of idiot raiders trying to steal all the boats, that is my job.
4. While I am doing this, my family/friends will raid the sailing center for all marine clothing, flares, weaponry, fishing tools, inflatable boats, and all of our wheeled gaswalkers, and load them onto our biggest sailboat, a 62 foot trans-pac yacht. Use our nylon towing lines to tie the powerboat and sailboat together, run a flashstart on the engine, and gun it out to Chaffee island. It is a currently non-operation oil drilling facility, with a screw of only 8 right now. On the island, they have the food, water, and other things needed to live in complete isolation for 40 days, on a crew of 70 PEOPLE. I would either take them out by force, or trade my massive stash of alcohol for a spot on the island. They have a full, concrete covered storage facility for their transport boats that can weather any storm. Also, they have a helicopter.
Depending on how badly Cali is wiped out after the, I will then either cruise the wreckage for survivors of our ruined kingdom (ala Wind Waker), make the oil drilling island my semi-permanent residence, or go out 28 more miles to Catalina Island.
