The Suffolk County Department of Health Services announced that the closure of all Atlantic Ocean beaches as well as all beaches on the southern shoreline of Fishers Island in Suffolk County is being extended and will remain closed through Saturday morning.
Meanwhile, the New York City Parks Department announced on Friday that city beaches will reopen on Saturday.
New Jersey officials have yet to announce plans for beaches this weekend after Gov. Phil Murphy declared a state of emergency on Thursday afternoon as Erin battered coastal communities with strong winds and waves that flooded streets and eroded beaches.
Murphy warned that "life-threatening rip currents will be present at all ocean beaches across the state" for the next few days.
"Absolutely no one should be in the water today or tomorrow," he wrote on social media.
He said winds could reach 50 mph, waves could be as high as 17 feet, and 1 to 3 feet of water could inundate some flood-prone areas.
State of emergency in NJ due to life-threatening rip currents and flooding
The National Hurricane Center reported Friday evening that Erin had weakened to a post-tropical cyclone, with maximum sustained winds of 90 mph (150 kph), and was located about 375 miles (605 kilometers) south-southwest of Halifax, Novia Scotia.
Despite being twice the size of an average hurricane, Erin so far has managed to thread the needle through the Atlantic between the East Coast and several island nations, limiting its destructiveness.
LONG ISLAND
Weather conditions significantly improved on Friday but the waves remain rough and the rip currents are strong on Long Island as well. Coastal flooding and beach erosion also remain concerns.
As a result, Suffolk County beaches will remain closed for swimming through at least Saturday morning, according to officials.
On Jones Beach, Saturday's scheduled summer fest has been postponed.
Dangerous surf continues as Hurricane Erin passes
Easthampton has reopened its beaches to foot traffic, but swimming and beach driving are still not permitted.
But some good news, Long Beach anticipated that swimming would resume on Saturday.
NEW YORK CITY
In New York City, swimming at all city beaches will remained prohibited on Friday due to dangerous rip currents and large breaking waves caused by Erin, but the Parks Department did announce city beaches will reopen on Saturday.
Beaches were closed to swimming Thursday in New York City, but that didn't stop more than a dozen surfers from taking on the waves at Rockaway Beach in Queens.
Scott Klossner, who lives nearby, said conditions were great for experienced surfers.
"You wait all year round for these kinds of waves. It's challenging, really hard to stay in one place because there's a heavy, heavy, heavy rip," he said. "But this is what surfers want - a hurricane that comes but doesn't destroy my house? I'll take that."

JERSEY SHORE
Despite the strong currents and powerful wave action, swimmers in Sea Bright were daring even though the sign leading to the beach warned people to stay out of the water.
The temptation to take a dip in the ocean is appealing, but there are no lifeguards on duty, so there is a big risk. Officials are asking everyone to be patient.
Jersey Shore towns saw some street flooding during Thursday night's high tide. The main street in Avalon became a river and the same happened in Margate.
The back bay bulkheads help to keep the water from rising in Sea Bright, where there were no major issues from Thursday night's onslaught from Erin.
