Why do news reports keep mentioning that Sandy will be making landfall on the day of a full moon? Is there a scientific significance or is it just superstition?

I understand the storm surge risks of hurricane landfall during high tide but what does the lunar phase have to do with that?

Tides are marginally stronger during a new or full moon than during a quarter moon, because the tidal effects of the sun and moon are added together instead of opposing one another.

This is already explained in the larger thread about Sandy in askscience.
