Much of Western Australia's west has had its biggest rain in two-to-three months, with parts of the Pilbara and Gascoyne have had a real drenching. Karratha ammassed 104mm, its heaviest rain in three months, and heaviest May rain in 38 years or records. Further south rain was mostly light and patchy but it did more than settle the dust in places, adding moisture to the soil in what's been a dry start to the season. In the Central Wheat Belt, Dalwallinu only gained about five millimetres since it started raining on Sunday morning, but it's their most rain since early March. In the Central West, Morawa had 20mm, their heaviest since nearly 70mm fell in mid-February. In the Lower West and South West only sprinkles of a millimetre or two were recorded, a bit more on the hills. Perth only had 0.8mm in its wettest day so far this month, a month in which the long-term average is about 120mm. Further showers and even storms are likely over a large area of western WA during the next few days as a weakening low moves over the region. Later in the week a front will bring another burst of showers, this time favouring the south. It looks to be the wettest week for WA since February.
