Thanksgiving Macy's balloons could be grounded for wind

The blustery winter weather making its way along the East Coast is already snarling travel plans for thousands, but the storm could claim another Thanksgiving tradition: the massive balloons at the Macy's Thanksgiving Day Parade.

According to a report from ABC News, the 16 biggest balloons won't be allowed to fly if winds peak at speeds higher than 23 miles per hour. Winds are projected to blow between 15 and 25 miles per hour on Thursday in New York City, with gusts as high as 40 miles per hour.

The balloons that could be grounded include some of the parade's most popular, including Spiderman, Sonic the Hedgehog, Spongebob SquarePants and Snoopy, accompanied by his little bird friend, Woodstock.

The 23 mile per hour limit for the balloons was set by a mayoral commission in New York in 1998. The rule was made following an accident at the 1997 parade, when a 40 mile per hour wind gust blew the Cat in the Hat balloon into a light pole, knocking its horizontal arm into the crowd, injuring two people. One woman spent 24 days in a coma from injuries sustained in the accident.
