No. It would be the clockwise flow around the high pressure behind the trof that would force it back on a westerly course. Will that happen? I don't know. But the flow around the trof wouldn't deflect it SW, if it were part of the steering regime. It would have SWly winds out front of it tending to steer it off to the NE. Hey, I got a big fat "F" in physics, but I do understand clocks.

I like to leave the physics for the models...Here's a link to the current 1000mb or surface level steering currents.

Though tropical disturbances are steered much more by the 500/850 mb flow (depending on the size). Of course winds still flow counterclockwise around an anticyclone, and clockwise around a cyclone.
