Make sure you are each carrying an ice axe. During the winter months, the lower slopes may look clear put near the summit it can be knee deep in snow. If you have never used an ice axe, then learn before you go and practise braking (arrest) when there is good stable snow on the slopes. You may need crampons, but is unlikely.
When on the summit, if there is snow be careful with conrnices i.e snow overhangs,as there has been many accidents with people standing on these thinking they are on the edge, yes they are on the edge of a very long drop!!
Above all else have fun!!!
