Obviously, Los Angeles was not enough — and neither was New York — because the ravenous sharks are back in Syfy’s “Sharknado 3: Oh Hell No!,” premiering tonight.

This time, the entire Eastern Seaboard from Washington, D.C., all the way down to Orlando, Fla., is in jeopardy of mass destruction from the freak storms that spew vicious, man-eating sharks like raindrops from their churning, tornado-like clouds.

But never fear, because Ian Ziering as the aptly named Fin is again revving up his chainsaw to save the United States from the bloody devastation.

Also on board is returning favorite Tara Reid as April from the original made-for-television movies — “Sharknado” and “Sharknado 2” — that became a pop culture sensation and megahits for the cable network.

All have been directed by Anthony C. Ferrante and written by Thunder Levin.

Fans are in for a treat with performances from David Hasselhoff, who plays Fin’s father, and Bo Derek, who play’s April’s mom. Nickelodeon stars Ryan Newman and Jack Griffo also have juicy roles and Mark McGrath returns as Martin.

But what is really fun about this latest installment of the Sharknado canon are the large numbers of cameos — everyone from Mark Cuban to Rick Fox to Ne-Yo, Kathie Lee and Hoda, Frankie Muniz, Penn Jillette & Teller, Ann Coulter, Chris Jericho, Jackie Collins, Lou Ferrigno, Jerry Springer, Michele Bachmann, Kim Richards, Kendra Wilkinson, Holly Madison, Reza Farahan, Ray J and Jedward. Even, gulp, Anthony Weiner!

Which ones of them will survive the Sharknado? Viewers in the U.S. and those in 87 other countries will soon find out.

(“Sharknado 3: Oh Hell No!” premieres on Syfy Wednesday, July 22, at 9 p.m. ET/PT.)
