Friday's rain will lead to sunny Saturday

A thunderstorm roared across Long Island on Friday, flooding roads, knocking out power and delaying motorists heading home in rush-hour traffic.

More than 9,300 customers out of about 1.1 million lost power in the storm, according to the Long Island Power Authority's website.

The Long Island Rail Road reported delays of 30 to 60 minutes east of Jamaica on all branches except Port Washington. Trains on that branch were running on the hour, instead of the usual half hour, said railroad spokesman Stanley Davis.

North Hempstead Town was working to assess the damage, town spokesman Collin Nash said.

"This rainstorm that just passed wreaked havoc," Nash said.

Reports came in across the Island of buildings being struck by lightning and roads being closed as a result of the weather.

The worst of the weather was expected to move out of the area Friday night and be replaced with scattered showers, said Tim Morrin of the National Weather Service.

In Nassau, live wires dangling across the roadway in Bellmore led police to close Merrick Road between Bellmore Avenue and Beverly Road.

In Suffolk, trees were down in Huntington Station and Hauppauge, wires down in Greenlawn and there was flooding in Lindenhurst.

By Saturday, the system will be gone, the National Weather Service said, leaving a mostly sunny day with a high of 83.

However, with a low-pressure system moving in on Sunday, there's a 30 percent chance of rain. Showers are expected after a clear morning.

The service said rain is expected again by midweek, with the chance of precipitation between 30 percent and 40 percent for Wednesday and Thursday.
