Narrative:

On final approach to detroit metropolitan inside the OM for runway 21L. We received a terrain alert from the GPWS. After realizing the cause the PF (the first officer) announced 'continue.' I became aware that the final flap confign was not selected. And the thrust reversers unarmed. Recognizing our position; I elected to continue without a confign change. The landing was uneventful with a higher than normal touchdown speed. Upon landing; I armed the reversers and we used them to exit the runway. Our debrief consisted of both decisions at the time of the alert to continue considering our proximity to the landing flare. Contributing factors were checklist discipline. A checklist was not called for at the proper time; and neither crew member verified usage.
