Long Islanders were advised Friday to limit swimming at 62 beaches due to potentially increased levels of bacteria after Thursday's heavy rain, the Suffolk County health department said.
The beaches listed in the advisory, which extends into Saturday morning, are in the towns of Babylon, Brookhaven, Huntington, Islip and Smithtown. Lake Ronkonkoma and Tanner Park beaches are closed.
These areas are “heavily influenced by stormwater runoff” and have limited water circulation, according to a news release.
Swimming and other water contact should be avoided until Saturday morning, after the waters have been flushed by two tidal cycles, the department said. The advisory will be lifted unless there is more heavy rain or elevated levels of bacteria.
