Singh was due to fly home to Ponte Vedra Beach, Florida, on Sunday after his win in the Pennsylvania Classic but due to the hurricane he was unable to return until Monday.
When he did get back, the storms had left his house with no power and water was coming in.
European Tour officials said that despite Singh's withdrawal, 44 of the top 50 in the world rankings would be teeing up in the tournament which starts on Thursday. They include three-times winner Tiger Woods.
