"It's likely the tidal portion of the Hudson River will also be greatly affected, and tides will be greater than normal because water won't be able to drain out of the Hudson at low tide because it'll be piled up into Long Island Sound and any other tributaries that it empties into," meteorologist Craig Allen said.
"It's quite likely that there will be some major flooding — moderate to major flooding — even in towns right along the Hudson River as far north as the tidal portion of the river goes. It's going to be quite a scene."
Allen warmed of the dangers of the hurricane.
"Everything you are reading about major inundation from record tidal flooding, river flooding and power outages lasting a week or more may come true," he said. "The Hudson and Delaware rivers will likely flood from ocean water backed up. This area has never been through anything like this. Never has a hurricane moved west toward Long Island, New York City and New Jersey."
