Default Penzance - radar totals

Looking at the radar rainfall totals (Friday 12Z to Saturday 12Z) in a bit
more detail:

The area west of St Ives had typically ~170mm with a maximum of 193mm ~4km
SW of the town. Zennor had 136mm. However, very sharp E-W gradient with much
lower totals to the East of St Ives - typically no more the 25mm. Similarly
with Penzence - the centre of which the radar suggests had ~25mm, but a few
km to the west in the 80-100mm range.

The highest totals were just offshore to the NW of the coastline with up to
200mm - however, maybe brightband played a part here - this region is ~37km
from the Predannack and assuming a maximum height of the freezing level to
be ~2km puts it at the 3 degree beam elevation...

the
details later....
