Brad hit some of my thoughts.
My first guess was that it is not feedback in the primary vocal mic/wedge and she even moves the position of the mic significantly to see if that helps.
Given the wind onstage, the fact that it starts at a transition, that it doesnt seem to increase in level, and the fairly low tone she sings in reproducing it leads me to believe it is a resonance rather than gain related feedback.
Add to the fact that she sings the problem to the monitor tech who for all we know was involved in a list of cue changes or making changes to the needy but deaf guitarist who needs changes for every songs mix. Fairly shortly after her first couple of song lines she smiles at something so I would guess he said something in her ears to acknowledge the problem.
As far as the minute that elaspes after that before the problem appears to be fixed, that seems quick to me considering the tech has a stage with a footprint twice as large as my house, a six or seven piece band plus a horn section and backup singers, probably 8-10 wedge mixes and possibly as many iem mixes that he found and fixed the problem at the source fairly quickly without hacking the stars mix to shreds.
My bet is the that the wind was exciting a tenor sax with a clip on mic, and since the wind often significantly changes at sundown, I am not sure how you would prepare for that in advance.
Once again I know all the statements about mixing with your eyes, but helping with this problem is something having the spectrograph in Smaart on the cue bus excels with.
