Torrential rain pounded southeast Queensland, Australia, on Jan. 10, 2011, bringing devastating flash floods to several communities just west of Brisbane. This image, made from the Multi-Satellite Precipitation Analysis (MPA) based on data from the Tropical Rainfall Measuring Mission (TRMM), shows the intense rain on Jan. 10.

The storm was relatively concentrated, with the highest rainfall west and northwest of Brisbane, according to a NASA statement. In the darkest blue regions of the image, the TRMM MPA recorded rainfall totals greater than 200 millimeters (8 inches) for the day. Weather stations on the ground reported similar totals.

The rain fell on already saturated ground, said the Australian Bureau of Meteorology. With nowhere to go, the water formed intense flash floods that ripped through the Lockyer Valley, killing ten people and leaving 78 missing, according to news reports.

The water drained east, pushing several rivers past major flood stage. Queensland's largest city and capital, Brisbane, and the nearby city of Ipswich, expected the floods to affect some 45,000 homes by Jan. 12, said Brisbane's Courier Mail.

The storm continued a trend of rainy weather linked to La Niña.

According to the Australian Bureau of Meteorology, Queensland had the wettest December on record in 2010, while the continent as a whole experienced its third wettest year in 2010. The extreme rain triggered widespread flooding across Queensland and New South Wales in December and January.
