Does the weather ever get better?

[Two-Six]

Hi all,
Here is the situation. I am at the end of a patrol and have no torps left. I have used my last three on a C3 cargo, and it's nearly dead, on fire and immobile. I have parked up next to it and now I am waiting for the weather to get better so I can use my gun on in to finish him off.

Here is the question. If I stay in one place, and zoom forward in time a couple of days, will the weather even get better?

s this a waste of time, or will the weather ever get better if I hang around long enough?

I am on day four or five now and it's still terrible, and too rough to turn the cargo's hull into a sieve with my AP rounds..

What shall I do? Give up and go home, or stay a bit longer?
