AHem - sorry about not being explicit on the non-imperial nature of our
weather reporting system. The thermals are pretty good at present with
cloudbase last weekend at 20,000 foot MSL (15,300"AGL)

One club member recorded a 13kt thermal in an L13, pity he had to
abandon it to let his nauseous passenger disembark...

Doesn't look too impressive till you realise that they're quoting thermal
strengths in Metres per second!
