Ninety-nine fires were burning across the state on Monday morning, with 26 of them still out of control.

The two most serious fires are in the Greater Hume area, in the state’s south, and are still at the second highest ‘‘watch and act’’ level.

But firefighters hope cooler weather on Monday will make it easier for them to contain those two fires.

Three homes were destroyed on Saturday in Minnimbah about 30km southeast of Wagga Wagga. 

Around 100 firefighters are working on containing the blaze, which has so far burnt 9000 hectares.

Despite the milder conditions, authorities are urging people near fires against complacency.

‘‘They need to make sure that they have their properties ready and that they know what they will do if a bushfire threatens their property,’’ the Rural Fire Service spokeswoman said.

More than 1000 firefighters are working across NSW to contain the fires on Monday.

They were aided by ‘‘very favourable’’ conditions overnight, the Rural Fire Service says.

An emergency warning for a bushfire in the Hunter Valley, near Singleton, was downgraded to the lowest level of ‘‘alert’’ overnight.

Several fast-moving grassfires were on Sunday threatening homes in the area.
