Just some very basic comments for using the hr-by-hr forecasts. Wave 1 starts at 07:00. Wave 1 runners with 4hr race times will finish at 11:00. Wave 2 starts at 07:30. The A-Frame cutoff is 4 hrs + 15 minutes from the start at 11:45. The cutoff for the PPA is 6 hrs + 30 minutes (14:00 for wave 2 runners). There is also a cutoff at Barr Camp at 3 hours from the start. The general weather pattern for PP is clear sky early in the morning followed by increasing cloudiness and afternoon showers/Thunderstorms. If it starts to thunder before you have reached A-Frame, you could be trouble because the cutoffs could be moved up.
