Narrative:
I was flying the river visual approach to runway 19 at dca; [when approximately] 4 NM from landing; we got a GPWS 'obstacle; obstacle' warning. I was scanning outside and inside the cockpit and did not feel we were near any obstacles that would trigger a GPWS warning. I did look down and notice that I was slightly below the advisory VNAV 'snowflake.' captain took the controls and made a slight correction to the glidepath and course. GPWS warning went away and we landed uneventfully.on the river visual approach to runway 19; we fly very close to some buildings as we come down the potomac river. It may have been a combination of being close to buildings; being slightly below the vpa snowflake; and having a momentary sink rate greater than normal that triggered the gwps warning.
