HOBOKEN, N.J. (AP) – New Jersey National Guard trucks are delivering ready-to-eat meals and evacuating the city of Hoboken.

About half the city remains flooded two days after superstorm Sandy struck. Thousands are still holed up in their brownstones, condos, and other housing.

The mile-square city is across the Hudson River from New York. The mayor’s spokesman, Juan Melli, said Wednesday many people are now asking to be evacuated.

Payloaders have been used to get people out for medical emergencies but Melli says the streets are so narrow they can get stuck.

Melli says the city is asking people with generators and boats to bring them to city hall, which is on dry ground and powered by a backup generator.

Mayor Dawn Zimmer on Sunday ordered an evacuation of basement and street-level units.
