New York City subways, buses and suburban commuter trains will begin shutting down at noon on Saturday, officials said.

The system-wide transit shutdown will begin when trains and buses begin their final runs at noon.

Hurricane Irene has weakened slightly to a Category 2 storm as it approaches the East Coast, where a hurricane warning has been extended to New Jersey.  It is expected to arrive in the tri-state area late Saturday.
