Rainfall Return Levels

33 years, 1989 to 2025

A day with at least 114.3 mm (4.5 in) of rain is expected about once in 2 years. A day with at least 447.8 mm (17.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Ponchatoula 4 E: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	114.3 mm (4.5 in)
5 years	166.1 mm (6.5 in)
10 years	211.9 mm (8.3 in)
25 years	287.1 mm (11.3 in)
50 years	359.1 mm (14.1 in)	Longer than the 33 years of record
100 years	447.8 mm (17.6 in)	Longer than the 33 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, 33 years of values from 1989 to 2025.

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: 406.4 mm (16.0 in) in 2021; 339.3 mm (13.4 in) in 2016; 211.6 mm (8.3 in) in 2015.
