Hmmmm.... It's one those calls you just really don't know what to do! I have visited quite a few weather sites and they are all giving rain, but coming in at a different times of day. Some are suggesting it being in as early as 10:00 am, with a chance of a break in the afternoon and some suggesting mid to late afternoon.
Mild moist air coming in from the South West this time of year usually means clag on the westerly slopes on the Bwlch. That said if it clear with the wind speeds predicted it could be quite good on Mickey's. May be the bigger question is that will it stay clear for us to get three rounds in?
If I was pushed to make a decision right now I don't think we will get enough to get three rounds and would call it off, but with quite a bit of a contradiction between the various weather site I suggest we hold and I will make a call by midday tomorrow. Hopefully by then will have a clearer pictures.
All the best
