A rain bearing cold front has clipped southwest Western Australia, bringing significant rainfall totals. Windy Harbour received 48mm to 9am Sunday, its highest 24 hour total since December 2008 and its heaviest October rain in a decade. At Cape Leeuwin, 30.2mm fell in the rain gauge, making it the heaviest October fall since 1999. It was four years since Albany residents have seen 20.8mm recorded in October. An unstable air mass in the wake of the front, has continued to generate light falls across the southwest of the state today. The heaviest falls were concentrated around the South East Coastal region, with 19mm recorded at Cascades and 18mm at Neds Corner. Light falls are expected to continue through into tomorrow, although edging further east and mainly restricted to the coastal fringe about the Eucla district. Looking further ahead, a low pressure system may develop around Wednesday or Thursday, potentially bringing a few more showers and the odd thunderstorm to the southwest of the state.
