Severe thunderstorms will bring large hailstones and a flash-flood risk to inland NSW as heavy rain belts catchments to the east, renewing the flood threat to the state's coastal rivers.
"We're bracing for significant rainfall right across NSW today," Flood Recovery Minister Steph Cooke said on Friday.
Severe thunderstorm alerts have been issued for parts of the Northern Rivers, North West Slopes and Plains and Northern Tablelands.
