A second nor’easter expected to strike New Jersey in the span of less than a week is already having some impact on travel.

At least 150 flights scheduled for Wednesday at Newark Liberty International Airport have been canceled ahead of the storm. Travelers are urged to confirm their flight’s status before arriving at the airport.

New Jersey Transit is also anticipating problems due to the storm. The agency tweeted Tuesday evening, “Due to projected snow accumulation in conjunction w/ local & county travel bans, it's possible for all North/Central NJ bus service, including to/from PABT, to suspend before afternoon peak travel.”

NJ Transit also announced a severe weather rail schedule for Wednesday, which means limited service. Cross-honoring will be in effect for Wednesday. NJ Transit employees are expected to be out at train stations assisting any riders who may have questions.

Wednesday’s storm is expected to bring over a foot of snow to some areas of the state. Parts of northern New Jersey could see around 18 inches of snow.

Gov. Phil Murphy declared a state of emergency for the state that went into effect Tuesday evening.
