In reply to Chubbs:
Monday was very heavy rain in the Central Lakes. Tuesday morning also wet. Today was a wet morning, now bright in Ambleside (and so is Langdale).
Pillar and Scafell will likely be pretty damp for a few days.
Pikes crag (on Scafell Pike) will dry much quicker, if you're wanting the really high crags. Otherwise go for S / SW facing crags. Gimmer springs to mind.
