The Suffolk County Department of Health issued an advisory Thursday against swimming in 63 beaches because of high level bacteria levels.
The beaches covered by the advisory are located in areas that are heavily influenced by stormwater runoff from the surrounding watersheds or adjacent tributaries, and because of their location in an enclosed embayment, experience limited tidal flushing.
This advisory will be lifted Friday, at 5 a.m., unless sampling reveals elevated levels of bacteria persisted.
