It seems to me the best local storm names tend to be tied to a holiday or otherwise significant date:
Following that tradition, our recent flood would be the Summer Solstice Flood of 2012. But I haven’t heard anyone call it that, and it’s been over a month.
What are you calling it? Any good ideas? Maybe if we come up with a good one there will be more federal relief money sent our way, so perhaps we should work the word “disaster” in.
