Extremely rough surf prompted officials to prohibit swimming Sunday morning at Robert Moses State Park and Jones Beach, but the ban has since been lifted.

The beaches remained open, but no swimming was being permitted for a time Sunday morning. At 11 a.m., parks officials said the ban had been lifted.

It comes as the National Weather Service has issued a high rip current risk statement through this evening along the South Shore of Nassau and part of Suffolk.

News 12 is told that lifeguards will be monitoring the conditions throughout the day.

Meanwhile, Nassau County has issued an advisory against bathing at 19 beaches Sunday. The county's Department of Health says it's a precautionary measure for the beaches that are known to be affected by stormwater runoff caused by heavy rain.

"Stormwater runoff can impact bathing water quality by elevating bacteria levels, which may cause exceedances of the New York state standard for bathing water quality," the department says.

The affected beaches include:
