From a week-starting range of nearly 20, the number of beach closures monitored by the Ocean County Health Department winnows down to five, with no new entries - plus, for the first time this week, no swim advisories.

The five closures are lake- and river-related: High and low beaches at Harry Wright Lake in Manchester, the lake in Ocean County Park in Lakewood, Bamber Lake  and Lake Barnegat's Middle Beach in Lacey, and Avon Road in Pine Beach.

The New Jersey Department of Environmental Protection records no closures of beaches that it monitors in Ocean or Monmouth County.

With a likelihood of scattered thunderstorms Saturday, the possibility looms of new inrushes of enteroccocus and fecal coliform bacteria in stormwater runoff to the ocean, bay, rivers, streams and lakes.

Health Department staffers begin a new round of tests Monday.
