Early Tuesday morning on appropriately named River Road in Sayville, the water also came in during high tide.
High tide is expected again there at 1:40 p.m.
For the North Shore of Long Island, the big story is snow. Lots of it.
From Huntington where the snow is piled high in people's backyards to Melville where it's piled high on top of people's cars.
The island got slammed with this storm.
"It's good to see some snow. After two years of nothing. It's a nice change. I like the seasons," said Ed Libretto, an East Northport resident.
There were concerns the combination of heavy, freezing snow and wind could lead to widespread power outages on Long Island.
But Tuesday, most power was restored.
Monday night evening, many side streets were packed with thick snow that turned to ice as the sun went down.
Drivers who thought it was safe to go out became stuck, making it impossible for plows to get through the clear that snow and ice away.
Nassau County Executive Laura Curran says the county saw 150 car accidents on Monday.

"Those who did venture out found it to be slippery and dangerous," Curran said.
Some parts of the island saw 16 inches of snow, and it's not even over yet.
"I think the worst of this storm is that it's relentless, it just keeps coming and coming, but our guys are doing a fantastic job, they keep going out and plowing, and then going out and doing it again, it's similar to the homeowners who have to keep shoveling the driveway and the sidewalks, and then an hour later they have to go out and do it again," Curran said.
Suffolk County mobilized 300 snow response vehicles while Nassau County had 115 plow trucks and 21,000 tons of salt and sand.
