I'd seen one of these that had been done for Hurricane Irene going around, that a lot of people probably thought was Hurricane Sandy. I created this one from a NASA satellite image (distributed by NOAA) from Sunday, October 28, 2012 at 1745zulu (6:45pm EDST).
I posted it to my Tumblr, and it's a bit downscaled from my original (3000 x 2400). The satellite photo is public domain and I've given my poster of it a CC license.
