Narrative:
ATC turned us onto the approach at voaxa intersection and 15400 ft which placed us high on the profile. Ege WX was reported 7500 ft broken 8 mi visibility. While descending on the arrival between hamos and barza we received a GPWS terrain warning. We executed a missed approach; came back around and landed without further event. Because we had been high on the approach I ended up rushed and somewhat behind on approach procedure; however; we were above the published minimum altitudes for the approach. The temperature was reported as -3 degrees C; so no altitude corrections were applied. On the second approach I stayed 300-500 ft above the descent profile until closer in to the airport.

Title: AN A320 CREW RPTS ATC KEEPING ACFT HIGH APCHING EGE IMC CAUSING EGPWS WARNINGS WHILE DSNDING RAPIDLY TO ACQUIRE A DSCNT PROFILE.
Narrative: ATC TURNED US ONTO THE APCH AT VOAXA INTXN AND 15400 FT WHICH PLACED US HIGH ON THE PROFILE. EGE WX WAS RPTED 7500 FT BROKEN 8 MI VISIBILITY. WHILE DSNDING ON THE ARR BTWN HAMOS AND BARZA WE RECEIVED A GPWS TERRAIN WARNING. WE EXECUTED A MISSED APCH; CAME BACK AROUND AND LANDED WITHOUT FURTHER EVENT. BECAUSE WE HAD BEEN HIGH ON THE APCH I ENDED UP RUSHED AND SOMEWHAT BEHIND ON APCH PROC; HOWEVER; WE WERE ABOVE THE PUBLISHED MINIMUM ALTS FOR THE APCH. THE TEMP WAS RPTED AS -3 DEGS C; SO NO ALT CORRECTIONS WERE APPLIED. ON THE SECOND APCH I STAYED 300-500 FT ABOVE THE DSCNT PROFILE UNTIL CLOSER IN TO THE ARPT.
