October 1, 2013 - Dust storm in South Australia

Dust storm in South Australia

Strong winds, high temperatures and dry conditions prevailed across the state of South Australia at the end of September, 2013. On September 23 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the region and captured this stunning image of a plume of dust blowing across the region.

Windy weather continued on September 30, when severe weather swept across the state, bringing storms and winds gusts up to about 105 km/h (65 mph), with at least a dozen stations reporting severe gusts greater than 90 km/h (56 mph). Although the wild weather brought some relief from the heat, dropping the mercury about 10°C, it also brought trees down – about 100 reports of trees and branches blocking roads, broken power lines and downed traffic lights were received across the state.

Earlier that same day the strong northwesterly winds blew dust from the Lake Eyre basin across Adelaide at sunrise, according to local new reports. Adelaide, the capital city of South Australia, is located well south of this image. It lies north of the Fleurieu Peninsula on the Adelaide Plains between the Gulf St. Vincent and the low Mount Lofty Ranges. Rains reduced the dust by the afternoon of September 30, and on the morning of October 1 the South Australian Bureau of Meteorology cancelled the severe weather warnings for the state.
