Narrative:

We were cleared direct to omaxi for the ILS 07 approach to montego bay. We had to deviate east of course for weather. Once clear of weather we were re-cleared direct omaxi. We were at 3000 ft and I started slowing and configuring the aircraft for the approach. I was at 180 kts and flaps 2 prior to omaxi. We were coming into omaxi at a 90 degree angle requiring a hard left turn to intercept the localizer. I did not want to overshoot the localizer due to high terrain to the south so I slowed and configured early. When cleared for the approach I turned slightly left to intercept the localizer inside of omaxi. Once localizer captured I started a descent to 1800 ft so I would not be above glide slope and put the gear down to make sure we were stable early due to weather. After getting the 2500 ft call we got a terrain warning at approximately 2400 ft. Disconnected the autopilot pulled the nose up and selected toga thrust. Advised approach control we were going around. Turned left away from terrain and climbed to 3000 ft. Got vectors for another ILS 07 approach.too steep of a descent on approach.know your exact position in relation to terrain.

Title: A319 flight crew reported receiving a GPWS terrain warning on approach to MKJS.

Narrative: We were cleared direct to OMAXI for the ILS 07 approach to Montego Bay. We had to deviate east of course for weather. Once clear of weather we were re-cleared direct OMAXI. We were at 3000 ft and I started slowing and configuring the aircraft for the approach. I was at 180 kts and flaps 2 prior to OMAXI. We were coming into OMAXI at a 90 degree angle requiring a hard left turn to intercept the localizer. I did not want to overshoot the localizer due to high terrain to the south so I slowed and configured early. When cleared for the approach I turned slightly left to intercept the localizer inside of OMAXI. Once localizer captured I started a descent to 1800 ft so I would not be above glide slope and put the gear down to make sure we were stable early due to weather. After getting the 2500 ft call we got a terrain warning at approximately 2400 ft. Disconnected the autopilot pulled the nose up and selected TOGA thrust. Advised Approach Control we were going around. Turned left away from terrain and climbed to 3000 ft. Got vectors for another ILS 07 approach.Too steep of a descent on approach.Know your exact position in relation to terrain.
