Narrative:

During the approach phase, we experienced a 'terrain warning' just after leveling off at ATC assigned altitude (2800 ft MSL). The aircraft was approximately 14.5 DME on the san 110.9 localizer. (Just outside of 'swaft' intersection.) after hearing the audio portion of the terrain warning 'pull up' 'pull up' we climbed the aircraft immediately to approximately 5300 ft plus or minus 100 ft and advised ATC of the deviation. We were IMC at the time of the warning in rain. ATC advised us to try and level 5000 ft and we complied. At that point we were given the option to intercept the localizer (runway 27) and continue the approach. We accepted the clearance and continued and landed on runway 27 in san diego without further incident. Note: there is an obstacle near the point of our terrain warning at (2791 ft) on approach chart (11-2) localizer runway 27. Also there is terrain in that vicinity contained at 4000 ft (1000 ft obstruction clearance).

Title: GPWS WARNING -- FINAL APCH VECTOR.

Narrative: DURING THE APCH PHASE, WE EXPERIENCED A 'TERRAIN WARNING' JUST AFTER LEVELING OFF AT ATC ASSIGNED ALT (2800 FT MSL). THE ACFT WAS APPROX 14.5 DME ON THE SAN 110.9 LOC. (JUST OUTSIDE OF 'SWAFT' INTXN.) AFTER HEARING THE AUDIO PORTION OF THE TERRAIN WARNING 'PULL UP' 'PULL UP' WE CLBED THE ACFT IMMEDIATELY TO APPROX 5300 FT PLUS OR MINUS 100 FT AND ADVISED ATC OF THE DEV. WE WERE IMC AT THE TIME OF THE WARNING IN RAIN. ATC ADVISED US TO TRY AND LEVEL 5000 FT AND WE COMPLIED. AT THAT POINT WE WERE GIVEN THE OPTION TO INTERCEPT THE LOC (RWY 27) AND CONTINUE THE APCH. WE ACCEPTED THE CLRNC AND CONTINUED AND LANDED ON RWY 27 IN SAN DIEGO WITHOUT FURTHER INCIDENT. NOTE: THERE IS AN OBSTACLE NEAR THE POINT OF OUR TERRAIN WARNING AT (2791 FT) ON APCH CHART (11-2) LOC RWY 27. ALSO THERE IS TERRAIN IN THAT VICINITY CONTAINED AT 4000 FT (1000 FT OBSTRUCTION CLRNC).
