Widespread flooding in the Top End while hot and wet in the south - Northern Territory in March 2007
Heavy rainfall at several locations caused extensive flooding in the Top End mainly due to an active monsoon trough in the area. In the south, the Todd River ran for the fifth time this wet season (fourth for the year). Temperatures were warmer than normal in the central and southern parts of the Territory.

Rainfall
Most of the Northern Territory recorded very much above average rainfall for the month of March 2007. Heavy rainfalls at several locations across the Top End, with some recording their highest on record, caused widespread flooding.
A persistent monsoon trough over northern Australia, with embeded low / tropical cyclones off the west coast of Australia, contributed to above average rainfall across the Territory. As far south as the Alice Springs district good rainfalls were recorded.
Oenpelli, Jabiru Airport AWS, Batchelor Aero AWS and Mango Farm received more than 3 times their monthly average with all recording more than 700 mm of rainfall for the month.
Some sites had their highest total March rainfall on record.
Maximum temperature
Mean monthly maximum temperatures over southern parts of the Territory were above average during March 2007 with some areas up to 2°C higher than normal. In contrast the daily mean maximum temperatures over central NT and the Top End were 1 to 2°C below average.
Some sites had their highest March temperature on record.
Minimum temperature
Mean monthly minimum temperatures over far southwestern parts of the Territory were well above average during March 2007 with some areas reaching 3 to 4°C higher than normal. Minimums were 1 to 2°C above average in some areas of the central Northern Territory and about average in the remainder.
Some sites had their lowest March temperature on record.
Some sites had their warmest March night (highest daily minimum temperature) on record.
Some sites had their highest March mean daily minimum temperature on record.

Notes
This statement has been prepared based on information available at 4 pm on Monday 2 April 2007. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Normals are long-term means based on observations from
the years 1800 to 2006.
They are not shown for sites with less than 10 years of record in that time, as they cannot then be calculated reliably.
The median
is sometimes more representative than the
mean
of "normal" 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,
normal in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a
percentage of the long-term mean.
