Yes
As Flying Press does 2x super effective damage to grass, ice, normal, fighting and dark, any Pokemon with a combination of those types, such as Scrafty, Cacturne or in your case Abomasnow, will take 4x damage from it under normal conditions.
There are potential exceptions to this, and further info can be found [here.][1]
Hope this helps
