The only ocean evidence of hurricane-assisted birds in Minnesota of which I'm aware are two sightings of Magnificent Frigatebird (9/22/88 & 10/1/88 - same bird?). The proximal cause of their arrival was probably Hurricane Gilbert, which made landfall in Mexico 9/16/88, moved up through Big Bend (9/18), and reached Missouri as a Tropical Depression 9/19.
The best chances for a pelagic would probably come from a strong storm heading due north near the TX/LA border. The eastern Great Lakes get shearwaters, storm-petrels, etc. from storms that hit the Carolinas and continue NNE. Paul
