64.5mm overnight, but much more just to the north over the moors (take
a look at the stationery white echo at
www.metoffice.gov.uk/weather/uk/radar/index.html
I suspect overnight totals 100mm above St Ives. A real test for the
new flood defence work The stream in my garden is at it's highest
level since we moved in Aug '07. Still raining

Got to go out - more details later.
