An apparent lightning strike sparked a basement fire at a home in Eatons Neck Sunday night, officials said.

Firefighters from Eatons Neck and Northport responded to the residence on South Harbor Road at 6:42 p.m., at the peak of a swift thunderstorm that darkened skies and brought high winds. Callers reported that a blaze started in the basement after a lightning strike, fire officials said.

The Eatons Neck Fire Department dispatched two pumper trucks, a rescue truck and an ambulance, though no injuries were reported, said firefighter Bob Leone. The fire was fully contained shortly after 7 p.m.

Further details, such as the extent of damage to the home, what was struck to spark the blaze, and how many people were inside at the time, were not available from officials.

David Urquhart, who lives next door on South Harbor Road, about 100 yards away, said he was visiting another neighbor during the storm when he saw a "very bright flash" and "almost instantaneous thunder," followed quickly by the sound of sirens. At first, someone he was with was worried his home had been struck.

"That's what we're always worried about," Urquhart said of lightning strikes.

Houses were also reportedly struck by lightning in Mount Sinai, although fire officials weren't immediately able to provide more information. A house fire was also reported in Terryville, but it was not clear if lightning was to blame.

Suffolk County police received a report of flooding at Christian Avenue and Quaker Path in Setauket and a vehicle stuck in water in Huntington at Creek Road and New York Avenue, as well a handful of calls about downed wires.

In Central Islip, firefighters spent two hours putting out a blaze sparked by downed wires on Wheeler Avenue, said Kevin McAteer, first assistant chief with the Central Islip Fire Department.

"It was just a nightmare trying to manage the traffic situation," he said. "People were trying to drive over the live wires."

Long Island Power Authority crews arrived on site, shut down power and were able to repair the damage, which caused outages to about 1,200 customers in the area. Power was mostly restored by 10 p.m.

At times, more than 3,800 customers in Suffolk County were without power, with the heaviest concentrations in Islip, Huntington and Brookhaven towns. By 10 p.m., 909 customers were still without power. Restore times for some areas were estimated at 3 p.m. Monday.
