Dropped iPhone 5 in the snow, how long till damage shows?

I dropped it in the snow.picked it up right away. I had a case on it… The only part that got snow in it a bit was the speakers. It still charges and works like 20 minutes later, the only thing weird is that the speakers sound a bit weird. I also had on a screen protector… Do you think it'll be okay. & suggestions to make sure it is okay?

Not if the speakers arent

Cool

Iphone is great
