Do any cave devotees have an idea of the lag time between heavy rain and seepage coming through?
I realise this is multifactorial, like if it's been dry for weeks it won't come through at all or whatever, but given how much time some people have spent there over the years I'm wondering have you any rules of thumb?
For reference, there was only a little bit of seepage on a few things yesterday, but yesterday afternoon and today there's been a lot of very heavy rain.
