Proceeding visually east of Moose Center at JAC Rwy 19. Daylight visual conditions; received GPWS caution/warning from Blacktail Butte. Was starting turn to right at the time to intercept final. Alert went away once turn was commenced. I never felt uncomfortable with the terrain separation; and was surprised that it was triggered.
Air carrier pilot reported receiving a short GPWS aural alert during the turn to final approach course to Runway 19 at Jackson Hole Airport.
