In reply to JohnBson:
Even if the freezing level does drop again as MWIS predicts there's no way that there will be climbable ice Beinn Udlaidh and the Cobbler is unlikely to freeze so quickly after the mild conditions and rain of the last couple of days. The Met office is showing heavy precipitation, initially rain but turning to snow, and strong winds which will increase the avalanche hazard in the Central Gully area of Ben Lui.
