Airlines are warning passengers to check their flight status before heading to the airport, as the U.S. East Coast braces for another blast of turbulent weather.

With a nor’easter bearing down on coastal states in the northeastern U.S., several airlines have issued travel advisories warning of potential delays or cancellations due to the weather.

Porter Airlines spokesman Brad Cicero said three evening flights to Newark and one to Boston from Toronto's island airport are cancelled due to the weather forecast.

All other Porter Airlines flights are scheduled to operate, Cicero said.

A travel advisory issued by Air Canada warns of potential delays or cancellations for flights to and from the New York region, Baltimore and other cities.

Air Canada spokesman Peter Fitzpatrick said the airline is monitoring the weather.

“If it deteriorates, some airports may reduce operations and that could affect us,” Fitzpatrick wrote in an e-mail to CP24.

For flights out of Pearson International Airport, he suggests people check the airport’s website for the latest on their flight’s status.

With a big storm expected to arrive later Wednesday, some U.S.-based airlines are also cancelling flights to and from the region.

American Airlines and American Eagle, for example, are suspending their operations in Philadelphia and at all New York-area airports.

The nor’easter is set to hit the region, including New York, New Jersey and Massachusetts, a week after superstorm Sandy lashed several states.

Forecasters are warning of powerful winds and minor flooding in communities that are still recovering from Sandy.

The storm may bring wind gusts as strong as 100 kilometres-per-hour and up to 50 millimetres of rain along the East Coast, said CP24 meteorologist Bill Coulter.

Further inland, communities from western Massachusetts to central Vermont and New Hampshire may be blanketed with up to 15 centimetres of snow, Coulter said.
