25 years	123.5 mm (4.9 in)
50 years	143.7 mm (5.7 in)
100 years	165.6 mm (6.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 101 years of values from 1882 to 1984.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 153.7 mm (6.1 in) in 1910; 152.0 mm (6.0 in) in 1963; 143.5 mm (5.6 in) in 1971.
