Some UK records

1901

Highest 120-min total 193 mm (7.6 in)Walshaw, W Yorks 19 May 1989

Highest 24-hour total (1800-1800) 341.4 mm (13.44 in)
Honister Pass, Cumbria 5 December 2015

Highest 24-hour total (0900-0900) 279 mm (11.0 in)
Martinstown, Dorset 18 July 1955

What you can be sure of is that on all these occasions it is highly
unlikely that the gauge was in the wettest spot.

Interesting that there is such a difference between the highest
1800-1800 24-hr total and the highest 0900-0900 24-hr total. Almost
invariably when somewhere is reported as having had a record wet day it
is the 0900-0900 24-hour totals that are being considered, although
this is seldom explicitly stated. The figures above show how misleading
it can be if only the 0900-0900 totals are considered.
