Just after midnight 683 responded to a vehicle fire at East Rd and Old Waterford Road.  High winds, blowing snow and -2* temperatures hampered the crews both enroute and on the scene.  The occupant reported the vehicle began to have engine trouble, she pulled to the side of the road and discovered a fire in the engine compartment.  On arrival 683 pulled a single 1 3/4" line to extinguish the fire.  PSP was on the scene and is investigating the accident.
