NSW State Emergency Service specialist crews have been sent to the state's north and floodwaters in Gunnedah are set to exceed last weekend's major peak on Friday night, after widespread rain across the state.
After more than 150mm of rain fell on parts of the Northern Rivers in the space of two hours overnight, the NSW SES sent a text message to people in the Tweed, Ballina, Lismore and Byron areas warning of the possibility of flash flooding ahead of rapidly deteriorating conditions today.
