Narrative:
On a visual approach in to mfr runway 32; we received an egpws warning of terrain; terrain; pull up. We were around yipug intersection intercepting the localizer back course approach at 7;800 when the warning was received. We complied with the warning and climbed up to 9;000. With no further warnings; we proceed to complete a visual approach to runway 14.the root cause of the event was the high terrain south of the airport and restricted visibility of said terrain due to it being night time. We had the airport in sight throughout the entire event and were adhering to the stepdown altitudes on the localizer back course approach. However; prior to yipug; we were not on the localizer back course final approach course; so terrain to the west of the approach may have triggered the warning.prior to the visual approach; we had been cleared to yipug and planned on intercepting final there. Perhaps if we had proceeded to ashie (IAF 5 miles prior to yipug) instead; and complied with the localizer back course minimum altitudes from that point; we would not have gotten the egpws warning. Weather permitting; landing on 14 may also be desirable when terrain clearance can't be accurately determined visually.

Title: CRJ-200 First Officer reported receiving a GPWS terrain warning on a night visual approach to MFR runway 32.
Narrative: On a visual approach in to MFR runway 32; we received an EGPWS warning of Terrain; Terrain; Pull Up. We were around YIPUG intersection intercepting the LOC BC approach at 7;800 when the warning was received. We complied with the warning and climbed up to 9;000. With no further warnings; we proceed to complete a visual approach to runway 14.The root cause of the event was the high terrain south of the airport and restricted visibility of said terrain due to it being night time.

However; prior to YIPUG; we were not on the LOC BC final approach course; so terrain to the west of the approach may have triggered the warning.Prior to the visual approach; we had been cleared to YIPUG and planned on intercepting final there. Perhaps if we had proceeded to ASHIE (IAF 5 miles prior to YIPUG) instead; and complied with the LOC BC minimum altitudes from that point; we would not have gotten the EGPWS warning. Weather permitting; landing on 14 may also be desirable when terrain clearance can't be accurately determined visually.
