Gunnedah State Emergency Service crews prepare for flooding sooner, disaster assistance extended to Tamworth, Gunnedah and Liverpool Plains

Piles of sand have been dumped at SES headquarters in Gunnedah as two weather fronts threaten to bring up to 100mm of rain to the region.

SES Gunnedah Unit Inspector Phill Miegel said crews were regrouping, and preparing differently compared to the flooding events that hit Gunnedah and Tamworth two weeks ago.

"There's a number of things we are doing differently this time," he said.

"We're preparing a lot sooner and we also have new apps on our phones where we can record where we've been door knocking and how far the river heights were."

Minor to moderate flood warnings have been issued for the Peel River and minor to major flooding is predicted for the Namoi and Gwydir River systems.
