Long Island Weather: Thunderstorms Knock Out Power To 900

Thunderstorms moving across Long Island Thursday morning have knocked out power to nearly 900 PSEG customers and the National Weather Service is warning of potential flash flooding. A hazardous weather outlook has been issued for the region.

Heavy rainfall and dangerous lightning are occurring. Showers and thunderstorms are expected to continue to lash the island through the afternoon before tapering off in the evening.

There is "certainly some potential for a few thunderstorms to be strong with a marginal risk for severe weather across much of the region for local damaging winds," the NWS said in a forecast discussion. There is a slight risk of flash flooding.

As of 8:34 p.m, PSEG Long Island is reporting that 897 of its customers are without power. See the outage map here.

Temperatures likely won't make it to 80 degrees on most parts of the island Thursday, but the heat is coming. We are looking at five straight days of highs near or above 90 degrees from Friday through the Fourth of July.
