Welcome rain continues to fall across NSW

Wet weather is expected to continue bringing relief to parts of NSW that were ravaged by bushfires.
Wet weather is expected to continue bringing relief to parts of NSW that were ravaged by bushfires.

Much-needed rain is continuing to fall on parched NSW farms and fire grounds with thunderstorms expected to hit the state's south over the coming hours.

Some 69 fires continue to burn across the state with 20 yet to be contained, the NSW Rural Fire Service says.

Firefighters are working to slow the spread of fire and build containment lines while the rain lasts, with increased fire danger expected later this week.

BOM meteorologist Rose Barr said Sunday's rain was concentrated across central and northern parts of the state on, and east, of the ranges.

The highest falls were at Forbes River which received 41.4mm by 6pm.

Other towns on the Mid North Coast and the northern rivers received up to 40mm, Ms Barr told AAP.

In the southern part of the state, higher winds saw storms race overhead quickly, resulting in lower measured falls.

A 100km/h gust was recorded at Narrandera about 5.45pm.

The storms will continue on Monday with a severe thunderstorm warning issued on Sunday evening.

"Tomorrow we have a very active thunderstorm day forecast, particularly across southeastern and central-eastern parts of the state, as well as parts of the southwest slopes," Ms Barr said.

But again they are likely to move quickly with some "extremely strong wind gusts". There could also be large hailstones.

Winds will shift and come more from the north and west mid-week, bringing drier and warmer air on Wednesday and Thursday.

"That means on both of those days we may end up seeing fire dangers increasing again and causing more problems for our fire agencies," Ms Barr said.

But moisture will thankfully return on Friday and the weekend.

Downpours over the past few days have provided relief for parts of drought-stricken NSW.

The death toll from the state's unprecedented bushfires climbed to 21 this weekend following the death in hospital of an elderly man burned in Cobargo on New Year's Eve.

The 84-year-old was taken from his home on December 31 to South East Regional Hospital before he was transferred to Concord Hospital in Sydney where he died in the early hours of Saturday.
