In the afternoon, flood warnings were issued for coastal streams between Rockhampton and the Gold Coast, and severe weather warnings were issued for the Capricornia, Wide Bay, Burnett and Southeast coast districts.

Notes

This statement has been prepared based on information available at 9 am on Monday 1 June 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Please note that the rainfall data from Bureau of Meteorology telemetry gauges (those with ALERT, AL or TM in their names) includes real-time operational data from automated systems and has not been checked.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably. *In this case, averages from a nearby suitable site have been used instead (these are marked with an *).

The median is sometimes more representative than the mean of long-term average rain.

The temperature anomaly maps are calculated with respect to the reference period 1961−1990. The rainfall decile maps are based on a reference period comprising all gridded analyses from 1900 to the present available at the time the deciles are calculated.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
