A lightning strike also started a fire near a Long Island Rail Road substation on Tuesday evening, according to the Metropolitan Transportation Authority. CBS New York reported that while service was suspended for some lines, all service has since resumed on a modified schedule.
"Even though lightning fatalities in the United States have been on the decline since records began in the 1940s, lightning continues to be a leading weather-related killer on a national and worldwide basis each year," according to AccuWeather Senior Meteorologist Alex Sosnowski.
So far this year, there have been 15 reported deaths due to lightning, according to the National Weather Service. Of them, the majority have occurred in Florida, followed by Kentucky, Arkansas, Texas, Missouri, Alabama and Georgia. Twelve of the victims have been male.

People were struck while standing near or under trees, fishing, lingering on the beach and staying out in the open in general.
"Always move indoors at the first rumble of thunder. If you can hear thunder, you are at risk of being struck by lightning," Sosnowski said.
He also stressed that the safest place to be during a storm is in a home or building with a roof and enclosed walls. Avoid standing near windows and screen doors or on porches and beneath overhangs, and never stand under a tree or a small group of trees.
If hiking, move down the mountainside as quickly as possible. A widespread, thick forested area in a valley is a relatively safe option when hiking or camping, when a vehicle is too far away.
