Six Nassau County beaches were closed to bathing on Monday due to storm water runoff, according to the county's health department.

The beaches -- Laurel Hollow Beach, Morgan Beach, North Hempstead Beach Park, Sea Cliff Village Beach, Tappen Beach and Theodore Roosevelt Beach -- are all on the North Shore and were closed as a precaution after the weekend's heavy rainfall, the department said.

Storm water runoff can lead to higher bacteria levels in the water, according to the department.

Updated information about beach closures is available on the department's recorded hotline, 516-227-9700.
