Harsh winter weather on the East Coast forced the cancelation of more than 700 flights on the day before Thanksgiving, one of the busiest travel days of the year. About 3,000 more flights were delayed, and more than 7,000 homes and businesses in the Northeast were left without power. New Jersey Gov. Chris Christie declared a state of emergency and emergency speed restrictions on highways and other major roads. Connecticut alone reported at least 125 accidents on slippery snow-covered roads.
