The South Fork took a beating from Tuesday's storm that battered beaches and flooded roads.
Massive waves were still hitting Main Beach in East Hampton on Wednesday.
Town crews created barricades of sand to try and keep the tide away. The heavy rain and surf still sent water onto the beaches, over roads and into some front lawns.
The storm surge also swept away sand, further eroding the coastline that residents say is shrinking with each storm.
Longtime Montauk residents say they hope the destruction will not leave a lasting mark.
"A hit like this makes it harder for it to come back," says Kathy Havlik, of Montauk.
Town officials are asking people to continue to stay off the beaches as the high surf is still hazardous.
