Another road related question.. Anyone know what conditions are like in Snowdonia, particularly the A55/A5 to Llanberis/Nant Peris and the A470 to Betwys-Y-Coed. Was planning to head to Nant Peris and do a walk over the Glyders from there but heard the A5 is pretty impassible, so we're thinking of maybe heading to Capel Curig along the A470 instead.
