With the heat wave almost at the point where it's about to break, a transformer on Eastchester Road in Morris Park reached its breaking point.
Firefighters battled a smoky fire in the Woodhaven section of Queens.
Two underground transformer fires burned in Forest Hills, Queens early Friday morning.
A transformer blew at International Drive and Route 46 in Budd Lake. Some 15,083 customers are without power in Morris County.
PSE&G said the transformer caught fire and fell, landing on the two cars and causing them to go up in flames as well.
The explosion happened around 9 p.m. Tuesday at Beach Channel Drive and Beach 92nd Street.
