Highway restrictions, train schedule changes and largescale flight cancellations went into effect Tuesday across the varied modes of transportation in Philadelphia as the region braced for a potent snowstorm Wednesday.
Hundreds of flights were canceled at the Philadelphia International Airport and a spokeswoman said travelers could expect hundreds more to be canceled.
American Airlines had already canceled more than half of its scheduled upcoming flights by early Tuesday afternoon. Airlines, the airport spokeswoman said, are asking passengers to change their travel plans.
"Overall, we expect more than 50 percent of today's flights will be canceled," spokeswoman Mary Flannery said in an email. On average, the airport handles about 1,000 flights each day.
The snowstorm that began in the Philadelphia region at noon Tuesday is to blame. It's the fourth nor'easter in a month, and most damaging to the prospects of flying out of or into Philadelphia is that the hazardous conditions will last 36 hours.
Up to a foot of snow is expected to fall in many places across southeastern Pennsylvania, New Jersey and Delaware, according to the NBC10 First Alert Weather Team. Strong winds and flooding in coastal towns are also forecast.
