We were on a left base to a visual for runway 33 in day VMC. The autopilot was off due to the fact that the moderate turbulence had kicked the autopilot off.  We had been encountering moderate turbulence from 10;000 feet to the runway.   We had a 48 knot tailwind on the left base which caused my First Officer to deviate right off course on final when he attempted to make a left turn to intercept a visual final to runway 33. The entire time of the approach we saw only green terrain on the main fight display (MFD) and I only saw two white and two red on the PAPI.  I also was monitoring the glide slope as reference due to the fact we were on a daytime visual.  When my First Officer (pilot flying) attempted the left turn to a straight-in visual; he overshot final due to the 48 knot tailwind.  I told him to turn back left to get back onto final.  He said 'correcting' and was correcting.  While turning back left we received a 'whoop; whoop pull up terrain.'  The First Officer pulled up and was completely clear of terrain.  At the same time I monitored his vertical speed and observed no terrain conflict.  He corrected to a straight-in final to runway 33 and the GPWS stopped.  We landed without incident. I am submitting this ASAP because neither my First Officer nor I saw any terrain conflict although we received a GPWS.  We should have taken a sooner turn due to the 48 knot tailwind on the left base.   We saw no terrain conflict on the MFD nor visually.
Captain reported receiving a GPWS terrain warning on approach to BTV when the aircraft deviated from the visual Runway 33 final approach course.
