The Bureau of Meteorology (BoM) advised thunderstorms are likely across the Blue Mountains and the north-east of NSW.
Weatherzone said yesterday rainfall between "20-40mm is forecast in the state on Sunday, while some areas could see 50-100mm, particularly with thunderstorms".
NSW SES Assistant Commissioner Nicole Hogan added the severe weather could cause flash flooding.
"Our catchments are very wet, and our dams are full, so it will not take a lot for floods to occur," Ms Hogan said.
"We need people to be mindful of their flood risks and be prepared."
Flood watches have already been issued for the Upper Macintyre, Gwydir, Peel, Castlereagh, Belubula, and Macquarie to Bathurst.
"In the event flooding does occur, there is a very real chance that roads can be impacted," Ms Hogan said.

Hail and strong winds are also expected.
It comes after Coffs Harbour only recently was hit by a freak storm which caused extensive damage to homes and businesses.
"Some of our communities, including Coffs Harbour, are still recovering from previous severe weather," Ms Hogan said.
"It is important you do what you can to protect your homes before the weather hits.
