Les Lever, acting station manager for the Bureau's Moree office, said residents in the North West slopes and plains should take care, with good rain forecast for this evening after big totals last night.

"There is a severe weather warning, with heavy rainfall and a possibility of flash flooding," Mr Lever said.

Burren Junction and Mungindi were two areas with the the highest rainfall last night, with 75mm at Mungindi and 70mm at Burren Junction.

Wee Waa and Narrabri also had heavy falls last night, Mr Lever said.
