The 19 Nassau County beaches closed over concerns about contaminated runoff after heavy weekend rains were opened again Sunday morning.
The closures by the Nassau County Department of Health had mostly affected beaches on Long Island Sound -- 14 on the North Shore and five on the South Shore. Parts of Long Island saw 2 1/2 inches of rain early Saturday.

Meanwhile, storm-related power outages were mostly resolved by Saturday afternoon. Sunday afternoon, LIPA's online outage map showed about 150 customers without power.
