Heavy rainfall that may lead to Flash Flooding may develop this evening about the Northern Rivers district, on both the Richmond River and Wilsons River, and possibly northeastern parts of the Northern Tablelands. This potential for heavy rainfall is expected to continue into Thursday morning, before easing by Thursday afternoon.
