Firefighters And Residents Brace For Soaring Temperatures In Bushfire Battle

NSW firefighters hope to seize on a temporary easing of conditions to get critical back-burning and containment work done before temperatures soar later this week.

Firefighters faced after another tough day on Saturday as dozens of fires continued to burn throughout the state, including the massive Gospers Mountain blaze near Sydney's northwestern outskirts.

NSW Rural Fire Service commissioner Shane Fitzsimmons on Saturday afternoon said they were hoping to see conditions ease over the next 24 hours.

He told the ABC it would allow firefighters "to really get in, consolidate and establish some containment lines" and conduct critical back-burning.

"Because we are expecting a return to another hot day, particularly Tuesday," Fitzsimmons said.

"We're expecting to see temperatures climb into the high 30s or early 40s right across parts of NSW."

Sunday's fire danger will be very high in the central ranges, northwestern, New England, Greater Hunter and northern slopes regions.

The danger will be high in the Greater Sydney, Monaro alpine, far north coast, southern slopes, north coast, ACT, southern ranges and Illawarra/Shoalhaven areas, and low to moderate in the rest of NSW.
