Prepare thyself for TV's superstorm blitz. At deadline, there were three announced forthcoming documentaries:

Superstorm 2012 (National Geographic Channel, Thursday, 10 p.m.) Another look at the inside of the storm and the "fatal surge" that left so many thousands homeless, with a focus on "the hardest hit in New Jersey and New York communities, who are still reeling in its aftermath." NatGeo also explores the question of whether Sandy was either an anomaly or a predecessor to another storm.

NOVA: Inside the Megastorm (WNET/13, Sunday, 7 p.m.) "Are superstorms becoming more frequent, more destructive, more deadly? Can we engineer our way to safety if Sandy is a sign of things to come?" This "NOVA" special also promises first-person accounts of those who lived in the most devastated areas.

Superstorm 2012: Hell and High Water (History, Sunday, 9 p.m.) Promises a look at the "anatomy" of Sandy, how it spun out of control and whether "this was just a taste of things to come ... the story of a superstorm that is changing the way we think about the weather and our world."
