Parts of the Illawarra region have been battered by intense rainfall, with Mount Pleasant recording a staggering 101.5mm of rain by 4.30pm on Thursday, February 26, 2026. This deluge occurred in less than eight hours, leading to a severe weather warning issued by the Bureau of Meteorology for heavy rainfall in northern Illawarra.
