Rainfall Return Levels

92 years, 1887 to 1992

A day with at least 48.2 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 100.3 mm (3.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Ida: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	48.2 mm (1.9 in)
5 years	61.3 mm (2.4 in)
10 years	70.3 mm (2.8 in)
25 years	82.0 mm (3.2 in)
50 years	91.1 mm (3.6 in)
100 years	100.3 mm (3.9 in)	Longer than the 92 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, 92 years of values from 1887 to 1992.

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: 104.9 mm (4.1 in) in 1940; 88.9 mm (3.5 in) in 1970; 84.1 mm (3.3 in) in 1931.
