In reply to mark s:
We just finished Hawkwing when the storm broke and saw a party on The Pedestal. Not sure what happened after that as we ran back to the car. Not sure why they wouldn't just be able to ab off if they needed to. Plenty of gear there. The storm passed in about 20 mins and the sun came out again so they'd probably have been able to finish the route before MR arrived.
It was pretty obvious a storm was coming. You could see it heading in over Stoke, so maybe setting off on a multi pitch route wasn't the smartest idea.
