Plan for a hot weekend across much of Australia, with severe thunderstorms possible in the southeast and a heatwave affecting the northwest. Check Bureau of Meteorology warnings before heading outdoors, especially for lightning and fire danger.
Where will the thunderstorms hit?
Thunderstorms are most likely across southeast Queensland, eastern New South Wales and Victoria on Saturday and Sunday. The main risk is damaging wind gusts and large hail. Isolated heavy rain may cause localised flash flooding, particularly along the New South Wales coast. The storms should ease by Monday.
Which areas are under heatwave conditions?
A severe heatwave is building across the Kimberley and Pilbara regions of Western Australia, with daytime temperatures reaching 44 °C in some spots. Parts of South Australia and the Northern Territory will also see above‑average temperatures. Overnight lows will stay high, making it harder for homes to cool. Keep hydrated and avoid strenuous activity during the hottest part of the day.
Is it safe to travel this weekend?
Travelling is fine if you stay flexible. Avoid driving through floodwater and never shelter under trees during a storm. In heatwave zones, travel early in the morning or late evening.
Will the heatwave cause power outages?
High demand for air‑conditioning can strain the grid. Check your energy provider’s load‑shedding schedule and keep a torch and phone charger handy.
When should I call emergency services?
Call 000 if you see a fallen power line, a building damaged by wind, or someone suffering heatstroke (confusion, red dry skin, no sweating).
