Decent rain en route to bone-dry southwest WA

14:29 AEST Welcome rain is coming to the parched southwest WA this week, possibly including Perth and Bunbury which are both having their driest 7 months on record. Many locations in the southwest will see the driest April on record, with much of this rainfall likely to contribute to May’s totals, as a cold front approaches the state on later in the week. Rainfall and thunderstorms are forecast in the Gascoyne region on Monday afternoon, before shifting to the Central West, Lower West and Central Wheatbelt regions on Tuesday.
