SCO, The pitch was cleared initially up til an hour or so before the match but the snow kept coming down. The ref decided it was fine to play on and that the under soil heating would help clear it during the match. The under soil heating was in fact on but there was too much snow on the surface for it to make any real difference, ineffective as it usually is on surface snow anyway, and the forecast they received at the match was that more snow was on the way, which is why the game was eventually abandoned.
