50 years	214.2 mm (8.4 in)
100 years	249.6 mm (9.8 in)	Longer than the 94 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 94 years of values from 1867 to 1965.

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: 246.4 mm (9.7 in) in 1954; 240.0 mm (9.4 in) in 1963; 227.3 mm (8.9 in) in 1921.
