Three hurricane-themed episodes of Seth MacFarlane's hit comedy shows Family Guy, American Dad and The Cleveland Show have been dropped from TV in the aftermath of this week's tornado disaster.

Severe storms swept across six southern states over a 24-hour period, beginning on Wednesday, devastating entire neighborhoods and claiming nearly 300 lives.

Executives at America's Fox network had planned to air three crossover episodes of MacFarlane's popular shows on Sunday, but the TV special has been postponed because of its storm storyline.

A statement from Fox reads, "In light of the recent storms that have affected the nation, Fox has decided to postpone the crossover episodes that were originally scheduled to air this Sunday."
