The rainfall on 20 September 1980 is our all-time highest 24 hr (09-09)
total on record here in Wokingham. We had 71.6mm. I do have a list of the
falls on that day for other stations in this area, with Yateley Manor School
being the highest with 84.3 mm. Other values over 70 mm were 72.6 mm at
Reading Road, 71.8 mm at Sonning Farm, 70.8 mm at Beaufort Park. There was
quite a sharp cut off to the east and west, with Slough Ragstone Road having
24.8 mm and Inkpen having 27.4 mm.

Could anyone direct me to suitable places to find daily rainfall figures
for September 1980 for a station in (north)(west) London ?


http://www.metoffice.gov.uk/media/pdf/t/3/Sep1980.pdf

tells me that

"during evening of 20th, band of heavy rain and thunderstorms moved
northwestwards from west sussex across south midlands and Wales"

and

http://www.metoffice.gov.uk/climate/...rackstorm.html

says 20th September 1980 tops the list of the 5 wettest days in Bracknell
with 70.8mm

but I don't know if the storms hit London.

I ask as I am interested in the modelling behind the overflowing of my
local sewage works into the Thames and the "typical" rain year used
includes September 1980 :

Version AB of the response mentions that the list of storm discharges has
been updated to include storms in September 1980 and then doesn't actually
list any in that month !
