Challenging conditions for firefighters in Vic and SA have eased as a rainband and cooler temperatures bring much-needed relief. 

Temperatures soared into the 40s over the weekend across the two states, with the hot, dry and windy weather causing extremely dangerous fire danger.  

The onerous weather provided a challenge for firefighters working to contain out of control fires burning in the Grampians, Vic, which had already burnt more than 76,000 hectares. 

Despite the challenging 48 hours, fire crews were able to contain the two fires burning in the Grampians as a cool and wet change arrived in Vic. Temperatures dropped around 10°C in four hours in Melbourne as the southerly arrived on Sunday evening. 

A cold front and associated low pressure trough sweeping the south of the country has brought some of the heaviest rain in four to six weeks across the state. The largest totals fell across western Vic and southeastern SA with 10 to 20mm observed in the 24 hours to 9am on Monday, January 6.

Melbourne already observed 21.2mm of rain in the three hours between 9am and midday on Monday. The rain impacting the state will continue into the evening before moving into NSW and Qld. 

One computer model suggests that by the end of Monday parts of Vic, southeastern SA and NSW could see 20 to 40mm end up in the gauges.

This dampening rain is good news for emergency services across the state that have been battling serious fire conditions for the past couple of weeks. While the rain is helpful for fire crews, the rainfall will not be sufficient to break the established drought conditions.

Temperatures will also remain cool for several days, before temperatures are expected to soar into the mid 30s to 40s later this week which will likely elevate fire danger once more.
