The Big Apple will likely dodge the worst of a nor’easter expected to slam the East Coast this weekend — though conditions should improve by Monday, meteorologists said.

Heavy rains and wind gusts topping 50 mph will batter the Jersey Shore, eastern Long Island and the New England coast — veering east of New York City, AccuWeather’s Carl Erickson told The Post.

“Minor to moderate coastal flooding can occur, worst on Friday and Saturday, driven by sustained onshore winds combined with this Saturday’s full moon, which will push tides higher than normal,” said Erickson.

“Some of the most flood-prone waterfront locations could see brief, minor flooding as early as this evening’s high tide, Staten Island is specifically prone to this, along with Long Island.”

Widespread rainfall totals of 1-2 inches are expected from southeastern New York through eastern New England, including Boston, according to AccuWeather Local StormMax.

The strongest wind gusts are also expected in these regions.

Tide levels across Staten Island and Long Island will reach 1-2 feet above average, with dangerous rip currents expected at ocean beaches throughout the weekend.

While major urban flooding is not expected, residents in vulnerable waterfront areas should prepare for minor to moderate coastal flooding around high tides over the weekend, with weather conditions gradually improving by Sunday, according to Erickson.

The core of the storm will move into the metropolitan area Friday into Saturday, when most of the rain will occur east of the five boroughs — and pinpoint areas out in Suffolk County.

Coastal flooding is especially possible on north-facing shores with localized power outages.

Erickson advises securing or removing all loose outdoor items such as furniture, trash cans and decorations before Friday. 

Residents should also avoid unnecessary travel to waterfront areas — particularly Staten Island’s South Shore and the North Shore of Long Island — during high tide.

“Expect a wet, blustery Saturday, with conditions improving by Monday,” said Erickson. 

More than a foot of rain is expected in parts of New England, including Boston and the Cape, with some locations receiving as much as 200% over their average rainfall.

The weather system is similar to a tropical storm and is slowly moving over the warmer waters in the Gulf Stream, which stretches from the Gulf of Mexico and flows through the Straits of Florida.

“Given that the developing nor’easter will be slowly moving over the very warm water of the Gulf Stream for two or three days, the storm may take on some characteristics that would resemble a tropical storm,” said AccuWeather chief meteorologist Jonathan Porter.

“Such hybrid storms are called subtropical storms. If that occurs, the storm could be assigned a name by the National Hurricane Center.”
