Weather May Ground Macy's Thanksgiving Day Parade Balloons

NYC changed rules after a 1997 accident led to four injuries

A blustery Thursday could mean more than canceled flights and frustrated travelers—it could result in the grounding of the biggest attractions at the 87th Macy's Thanksgiving Day Parade in New York.

Winds greater than 23 mph and gusts of 34 mph would keep SpongeBob, Snoopy, Pikachu and the rest of Macy's helium-packed behemoths firmly on the ground.
