A broad arc of dangerous thunderstorms is moving over eastern Australia this afternoon, prompting severe storm warnings from central Qld to southern NSW.
The animation below shows the massive band of storms, which has formed ahead of an approaching upper-level trough associated with an upper-level low centred over southern NSW.
At one stage on Wednesday afternoon, a bow echo formed as a line of intense storms tracked from the Southern Tableland towards the South Coast in NSW. This radar feature highlights the presence of powerful winds that are contorting the shape of storm’s precipitation band, which is a signature of a mature severe thunderstorm.
