A broad low pressure trough stretching from Western Australia's Kimberley to the far southwest of the state created significant rainfall about the Lower West and western parts of the Great Southern. The trough brought widespread falls of between 1-15mm from the coast around Mandurah to inland areas near Narrogin in the Great Southern. Jarrahdale received 36mm overnight, making it the wettest March day since 2010, where 57.2mm fell. Mount Solus gained 45mm to 9am this morning, an amount generally exceeding the monthly total and makes it the highest daily total in March since 2004. Other notable mentions include Dog Hill (27mm), Serpentine (14mm) and Wigarra (14mm). An approaching cold front and trough may bring some more falls to the region on Tuesday 25th, although likely to be less than 5mm.
