Rivera said a friend of hers had already called the Cajun Navy, the ragtag team of Louisiana boaters who plucked dozens of stranded people from the rooftops of their flooded homes last year in hurricane-ravaged Houston, to come get her.
"Half my dock is floating," she said. "Our house is completely surrounded by the ocean on all sides. I feel like our house could go at any minute. ... We already have a foot of water in our garage and the neighbor's house is completely flooded out."

Rivera said she and her husband had ridden out other storms at home. She said they remembered how difficult it was for residents to return after Hurricane Matthew in 2007.
Plus, Rivera said, her husband is a doctor and they wanted to be around in case anyone needed his help. But now they need help.
"It's difficult for me to watch," she said. "Every angle that I look, I'm surrounded by ocean."
Rivera was not the only person in need of saving. Just north of where she was marooned, rescue crews in Craven County were busy.
"We currently have had over 188 calls for rescue of 488 people and the calls are still continuing to come in," said Craven County spokeswoman Amber Parker. "We have people that are reporting they're trapped in attics, they're on their roofs, and also in vehicles that are flooding."
Parker said they've deployed five swift water rescue teams and are also working with the North Carolina Emergency Management team — and the Cajun Navy as well.
"We do have people calling in themselves," Parker said. "We have individuals that are having family members contact us. They've been without power for a significant amount of time now and their phone batteries are just wearing out and so we've got family members calling and continuing to call and we're trying to get to everyone as fast as we can."
In Wilmington, help apparently came too late after a tree fell on a home and trapped three people inside.
NBC's Lester Holt, who was on the scene, reported that responding firefighters were able to get one of the victims out of the house and that the person appeared to be conscious.
A short time later, firefighters were seen emerging from the shattered structure with despondent looks on their weary faces. Their body language spoke volumes — they could be seen taking a knee to pray.
