I think the northern migration will start at a trickle, slowly start increasing but still slow enough people don't really notice, and then suddenly and without much warning become a flood.
Just need to make sure you sneak in before that flood, but if you try to time it just right you'll probably wait too long and be in the same situation as everyone else.
