Though I wont be around (fly back north tomorrow AM!), the forecast looks better from tomorrow PM onwards and not so bad for Sunday:

There was no evident damage when I went up there during the week but would hope that a member of the team would report back after they've been to the track tomorrow?
It will be damp but we've all been there before when it's like that!
