A three-alarm fire struck the Weis Market store in Gap early Sunday morning. Firefighters were dispatched to an automatic alarm at the store and quickly upgraded the fire alarm to a building fire. The fire eventually went to three alarms bringing over 40 pieces of firefighting equipment to the scene from both Lancaster and Chester Counties. The Pennsylvania State Police Fire Marshal is on the scene investigating the fire. A cause has not yet been determined. As of 6:30 Sunday morning firefighters were continuing to extinguish flames inside the building.
