You have the right idea My Dear Hogwartian, the wind indeed is a sign, but of what? What can you see and observe as the wind blows against you? You are close in thinking it's blowing you in a certain direction, but is it trying to tell you something. As annoying and as bitterly cold as it is, it is a clue to be interpreted. Can you predict something from it?

It's a good thing you have upped the grip on your wand for such strong winds would certainly tug it from your hands if you hadn't done that and your insulation charm is holding steady, keeping you warm from this unforgiving cold.

As you move southeast, snow keeps piling in the cuts you are making and the north wind is blowing hard against you, hampering any progress in moving eastward and forcing you southwards.
