Human Factors; Procedure
We were planning to do a visual approach to MFR runway 32 and were sequenced behind an aircraft doing the same thing. For spacing reasons and because there was an unreported layer of clouds; we were vectored onto the LOC/BC-B approach. The Captain briefed the approach on the downwind vector and we finished just as we were given the base vector. I asked for and received flaps 8 and 20 and we were told to turn to a final heading and maintain our current altitude (8700) until established. We were in and out of the clouds at this time. I initially bugged what I thought was the next altitude (7800) but the captain corrected me and I bugged 8400 ft. Just as the localizer captured but before we started a descent; we received a 'Terrain; Terrain' warning followed by 'Pull up'. I added max thrust and pitched up slightly but did not hit the TOGAs or really get the nose up. The Captain prompted me and I continued the maneuver. I climbed to approximately 9500 feet before leveling off (I didn't know exactly what altitude to climb to and didn't want to climb too far and cause a potential traffic conflict; even though I didn't see any traffic). We actually could see the airport from that position so we executed a visual and landed without incident.I believe that the cause of the event was either a poor vector by ATC or oversensitivity of the EGPWS. We couldn't have prevented this event. However; I believe I could have performed better. I had briefed terrain as a threat but didn't review the EGPWS escape maneuver. This was the first time that I had performed this maneuver for real and the first time I had practiced it or really even thought about it since initial sim. The escape maneuver is now on my list of things to periodically review.
I believe that our vector onto the LOC BC from the southeast at 8700 placed us in close proximity to terrain just south of ASHIE intersection of 7500. Without having the gear down that could have set off the EGPWS warning. We could have asked ATC for a higher vectoring altitude.
Air carrier flight crew reported taking evasive action after receiving an EGPWS terrain warning on a visual approach to Runway 32 at MFR. The ATC vector was possibly a factor in the incident.
