I live in FL too, and never experienced this. My house is air conditioned too....but I have developed film without power for days, outside, and never had this problem.
From the pictures...That looks like ALOT of water would have to still be on those negatives...like a visible amount of water still on the negative?
I am with Chris - looks like maybe way too much photo-flo to me too. The last picture, is that dried on the negative? It is shiny right? Or am I crazy?
