Yesterday morning the State Emergency Service (SES) Macquarie Region was watching several rivers including the Talbragar.

By early afternoon it was warning of minor flooding next week at Collarenebri and Walgett.

The Orana team of the NSW Rural Fire Service also was vigilant, despite rain on Australia Day "quietening things down a bit" in and south of Dubbo, team superintendent Lyndon Wieland said.

On Saturday night at Euchareena, volunteers extinguished a fire in trees hit by lightning but had "quite wet" ground on their side.

Mr Wieland said north of Dubbo had not shared in the moisture windfall and stormy weather this time of year did not provide the blanket protection of good general rain.

He urged against complacency because sunshine could make wet patches vulnerable to fire.

The fire danger rating for the Orana region, taking in Dubbo, Wellington and Narromine, was high yesterday.

"We need good general rain across the Orana area," Mr Wieland said.

At its Bultje Street headquarters, the SES Macquarie Region was busy writing bulletins.

Controller David Monk issued a flood watch for the lower Namoi River at and downstream of Bugilbone, along with a minor to major flood warning for the Barwon River at Mungindi.

"Combined with flood waters flowing from the Gwydir River, major flooding is also expected at Mogil Mogil later next week with minor flooding expected at Collarenebri and Walgett," he said.

Mr Monk predicted "some nuisance minor flooding" along the Talbragar River downstream of Elong Elong.
