Spring rain spreading across the country!

By the end of the week, most of the country will have seen rain, and it's all from one system! First it was WA, and now a low pressure trough is spreading rain and storms across the southern NT and most of SA. The moisture-ladden cloud will continue to spread east affecting western parts of NSW and QLD on Wednesday, before moving through much of eastern Australia during Thursday, Friday and the beginning of the weekend.

In the 24 hours leading up to 9am Monday, most parts of southwest WA picked up 5-15mm with Perth one of the only places to miss out. There were isolated pockets that received torrential downpours underneath intense thunderstorms. This included 53mm in Wongan Hills (Central Wheatbelt), its heaviest October rainfall in over 100 years!

Today, the rain and thunderstorm activity is affecting southern parts of the NT and most of SA. This rainfall comes as a relief to the Red Centre which has been ravaged by bushfires over the last six weeks. Widespread falls of 5-15mm are expected but once again, these isolated thunderstorms have the potential to be severe with heavy falls, damaging winds and small hail. The rain is likely to arrive in Adelaide during the late afternoon/evening.

On Wednesday/Thursday, rain and storms will spread across most western and inland parts of QLD, NSW, VIC and TAS, before affecting the east coast late Thursday/Friday and the weekend. Isolated pockets could receive heavy falls from thunderstorm activity.
