From the wind to the waves, Hurricane Lee will impact parts of Long Island even as it stays out to sea.

Communities along the East End prepared Thursday for the risk of high tides and coastal flooding.

The Town of Southampton already declared a state of emergency and some parts of Tiana Beach already saw flooding on roadways.

A coastal flood advisory goes into effect starting Friday night.

Waves came up over the dune in Hampton Bays and went through a piece of property and on to Dune Road. Crews were working to fortify the area on Thursday.

Southampton Town Emergency Manager Ryan Murphy said if they don't build up the dune, "what is now an overwash may actually turn into a breach where the ocean and the bay connect in the middle, and then it can start to degrade the roadway and the land around it, and we don't want that to happen."

The town says it surveyed the entire shoreline ahead of the storm using drones to document pre-storm conditions. This will help with assessing any potential damage.

Tommy Panebianco owns The Hamptons Watchdog Group, which looks after dozens of homes across the East End. He said now is the time to prepare your home for the threat of water damage.

"Window wells, if you have a basement. If you don't have plastic covers, make sure that those window wells are dug out and they have at least one inch of rock to absorb the water," he said. "That's for that to not pool up and get into the windows, into the basement, and cause any flooding in your basement."

He also recommends cleaning your gutters to prevent logs and leaks into your home as well as to check for any leaks in your roof or any skylights.

PSEG Long Island's senior director of Emergency Preparedness Larry Torres says the real cause for concern to them is the wind.

"With the heavy rains we've had over the past few days, it will weaken some of the trees," said Torres. "We are preparing to stage some of our resources, internal resources in that area so we can respond to any potential outages."

Panebianco also says to take in and secure any outdoor items that could damage your home.

"Umbrellas, if they're there and closed, that's still not good enough. They should be laid down and stored away," he said. "For furniture, you could have a few of them.

They want to be taken away from the property, away from the home and you want to put them together anchored down."

Many forecasts say Lee will stay hundreds of miles off of the coasts.

"We want to be prepared in case it wobbles a little bit to the west and maybe those winds increase slightly but the forecast is pretty confident," said Torres.

If you lose power, report it by calling PSEG LI or you can even contact them on social media.
