In reply to Tim Davies:
I parked at the car park above Aber falls today. Skins on at approx 300m. Worthwhile skiing off Foel Fras and down from Drum back towards Aber. Top of Drum was icy and lots of sastrugi. Difficult heading down from there to the bwlch before heading up to Foel Fras. On the return only the top 20metres off Drum were icy before hitting good snow. I went as far as Foel Grach, decent turns off the top but probably not worth the skin over.
Road up to car park above Aber was completely clear today, no issues.
Interested to hear if anyone has been out elsewhere in Snowdonia.
