Nassau County health officials on Thursday lifted an advisory against swimming at 14 North Shore beaches.

The county's Department of Health had issued the advisory Wednesday as a precautionary measure because of heavy rainfall.

Bacteria levels at beaches known to have substantial storm-water runoff can climb, failing meet the New York State standards for swimming, according to the health officials.
