Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Rainfall Return Levels

57 years, 1939 to 2001

A day with at least 71.0 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 175.7 mm (6.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Colonia Empleado: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	71.0 mm (2.8 in)
5 years	92.4 mm (3.6 in)
10 years	108.9 mm (4.3 in)
25 years	132.9 mm (5.2 in)
50 years	153.1 mm (6.0 in)
100 years	175.7 mm (6.9 in)	Longer than the 57 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, 57 years of values from 1939 to 2001.

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: 199.9 mm (7.9 in) in 1956; 130.3 mm (5.1 in) in 1948; 127.0 mm (5.0 in) in 1976.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Colonia Empleado, at 1997. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1997 ran 0.8 C (1.4 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Colonia Empleado, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1997	-0.8	-1.4	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
