Narrative:
This is a second attempt to submit this report -- received message that first report was unable to be processed. While in IMC conditions and on vectors for a localizer runway 27 approach at san, we were given a descent to 3800 ft MSL. We were cleared to maintain 3800 ft until intercepting the localizer. Approaching 3800 ft MSL, approximately 15 NM east of the airport, we got a GPWS warning 'terrain, terrain.' we executed an immediate climb per S80 OM procedure to approximately 4800 ft MSL. GPWS warning stopped in climb. Once established on the localizer at 4800 ft, we began a descent with no further GPWS warnings. ATC was notified of excursion and reason. Radio altimeter never showed movement indicating ground closure during event. Captain was PF.

Title: SUPER MD80 ON VECTOR TO RWY 27 MAINTAINING 3800 FT. GOT GPWS AND FOLLOWED SOP AND BEGAN CLB TO 4800 FT BEFORE WARNING CEASED. REMAINED AT 4800 TILL ON THE GS. NO FURTHER PROBS.
Narrative: THIS IS A SECOND ATTEMPT TO SUBMIT THIS RPT -- RECEIVED MESSAGE THAT FIRST RPT WAS UNABLE TO BE PROCESSED. WHILE IN IMC CONDITIONS AND ON VECTORS FOR A LOC RWY 27 APCH AT SAN, WE WERE GIVEN A DSCNT TO 3800 FT MSL. WE WERE CLRED TO MAINTAIN 3800 FT UNTIL INTERCEPTING THE LOC. APCHING 3800 FT MSL, APPROX 15 NM E OF THE ARPT, WE GOT A GPWS WARNING 'TERRAIN, TERRAIN.' WE EXECUTED AN IMMEDIATE CLB PER S80 OM PROC TO APPROX 4800 FT MSL. GPWS WARNING STOPPED IN CLB. ONCE ESTABLISHED ON THE LOC AT 4800 FT, WE BEGAN A DSCNT WITH NO FURTHER GPWS WARNINGS. ATC WAS NOTIFIED OF EXCURSION AND REASON. RADIO ALTIMETER NEVER SHOWED MOVEMENT INDICATING GND CLOSURE DURING EVENT. CAPT WAS PF.
