A year with missing days can understate an extreme.

Rainfall Return Levels

30 years, 1968 to 1999

A day with at least 90.9 mm (3.6 in) of rain is expected about once in 2 years. A day with at least 206.9 mm (8.1 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 30 years of values from 1968 to 1999.

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: 170.8 mm (6.7 in) in 1991; 169.0 mm (6.7 in) in 1990; 153.7 mm (6.1 in) in 1997.
