This includes subways, buses, ferries, PATH, Metro-North, Long Island Railroad, and (perhaps obviously) AirTrain. New Jersey Transit will suspend all rail service until Thursday at 8PM tonight. No re-start time for the MTA has yet been announced. Wherever you are at 11PM, you’ll likely be there for 36-48 hours.
UPDATE: Gov. Cuomo has also declared a ban on all non-emergency vehicular traffic beginning at 11PM, warning that those caught on the roads will be ticketed and fined $300.
