Well you can see it coming, regardless of the fog of war - and the screen could rumble if it's close by (an explicit count down would work). I guess it could only knock-up people that are facing it - with people with their back to it merely being picked up. Alternatively it could just be a slow, and not apply any hard CC at all - the wave will slow you as it whooshes past, but doesn't actually CC you. Or, the screen could just go black for 0.25 seconds, and when it fades in the map's already covered in snow. Everyone is invulnerable while the screen is black (so you could, in theory, make plays like on Shaco's ult where you dodge things in those 0.25 seconds) - maybe have the screen rumble for a second or so before it happens.
