Airport; Human Factors
On downwind to runway 25L at LAS we were cleared the visual approach. A left turn and descent was initiated toward the final approach course and while on dogleg to final a 'terrain; terrain' was issued by the GPWS.  A climb was initiated and once clear of terrain by reference to the ND the approach was resumed.
ATC vectored the flight off the KEPEC 3 arrival very early in the arrival procedure. Eventually the flight was given a 050 heading and descent to 6800 feet well south of the field. While on that vector; ATC cleared the flight for a visual approach to runway 25L. The flight left the last vector heading and altitude and started a series of heading changes towards the final approach course. While descending the EGPWS gave a 'caution terrain' followed almost immediately by a GPWS 'terrain; terrain.' The flight path was aggressively changed by selecting TOGA and pulling up. The warning stopped immediately and upon confirming terrain clearance on the ND; the flight leveled off and proceeded towards the final approach fix. The remainder of the approach was uneventful. While debriefing the event; the pilot monitoring stated that he did see some yellow on the ND prior to the warning. As the pilot flying; I was not aware of the yellow on the screen due to looking towards the runway while flying the visual.
A319 Flight Crew experiences an EGPWS terrain warning at 6;500 feet while on a night visual approach to LAS Runway 25L from southeast of the airport. An immediate climb is initiated and the approach is continued to a normal landing.
