A fast-moving thunderstorm swept across Long Island Wednesday night, causing power outages and electrical transformer fires, authorities said.
More than 5,000 customers were without power on Long Island as of 9:20 p.m., said PSEG spokeswoman Elizabeth Flagler. Of the affected customers left in the dark, 3,500 were in Nassau, with 1,800 more in Suffolk, Flagler said.
“Nassau got hit the hardest,” she said. “Crews will continue to work overnight and restore power as quickly as we can.”
Suffolk police reported a transformer fire about 8:45 p.m. on Church Street in Patchogue. A second transformer fire was reported about 8:30 p.m. near Great River Road and Riviera Court in Great River, police said.
There were reports of power outages in Huntington on East Main Street and Park Avenue and Park Avenue and North Woodhull Road Wednesday night, Suffolk police said.
The storm came after another warm day across Long Island with more sun and heat expected for the rest of the week.
Showers and thunderstorms are possible into Thursday, bringing the potential for gusty winds and heavy rain, the National Weather Service said.
The odds are 40% that Suffolk will see strong or even severe isolated thunderstorms Thursday afternoon and into the night, the weather service, which issued a hazardous weather outlook.
Highs in the mid-80s are predicted.
Look for sunshine and highs in the mid-80s for Friday to Sunday. Monday and Tuesday are expected to be much the same, but just a few degrees warmer, the weather service said.
