Fire broke out at at a house at the corner of 8th and Duss Avenue (802 Duss Avenue) this morning, right across the street from Ambridge Area High School. Bevaer County Radio News Correspondent Sandy Giordano reports that the flames erupted at the same time that Ambridge teachers were on the picket lines during their 3rd day of their strike. The fire caused a power outage in the area, which prompted officials to open up a warming center at the Ambridge borough building (in the fire station). No injuries were reported.
