Narrative:

Night visual approach to psp. Lost situational awareness and had a terrain warning. We briefed the terrain and egwps warning potential that is on the 10-7 chart. West side of valley. We also briefed the wind gust and gust factors. I thought we had cleared the high terrain east of the airport and began a slow descent. I was checking the RA (radar altimeter) readout and were above 2500 ft. Shortly received terrain caution; I added power and began a climb; RA showed 1500. Then received the warning. Added more power and climbed. RA showed 1100. We cleared that terrain and continued to a normal landing. As we were correcting the flight path approach control [asked] if we had the terrain in sight.I mistakenly thought we were clear of the terrain. Night time and the lack of lights on the east side of the valley made it difficult to see the terrain. I have also done many night visual approaches here and may have been too complacent with the terrain east of the airport. We spent time briefing the terrain west and also the gusty winds at the airport. I didn't brief the terrain east and that contributed to the event. I think I became fixated on the threats briefed and lost the big picture.I will spend more time reviewing the airport and surrounding terrain even when I feel familiar with the procedure. Also being aware of all threats and not fixating on the obvious ones.
