Parts of South Australia, Victoria and Tasmania will experience a burst of warm weather at the start of this week, briefly increasing fire danger ratings in some areas.

The satellite images below show a cold front crossing southwestern Australia on Monday morning.

This animation above reveals a large field of speckled clouds on the western side of the front, indicating a cold air mass coming from the southern Indian Ocean. Ahead of the cold front, a much warmer air mass is being driven towards southern Australia by a strengthening flow of pre-frontal northerly winds.

Warm air ahead of the approaching cold front will cause temperatures to climb around 8 to 12°C above average in parts of SA, Vic and Tas on Monday and Tuesday.

On Monday, temperatures are forecast to reach around 30°C in Adelaide and over 40°C in the west of SA. This heat is expected to cause Extreme fire danger in SA’s West Coast district and High fire danger in other western and central parts of the state on Monday.

A relatively weak southerly change will then bring cooler air to southern parts of SA on Tuesday as the hotter air is forced further east into Vic, Tas and southern NSW.

Melbourne is forecast to reach 29°C on Tuesday and Hobart should reach around 25°C, which are about 8 to 9°C above average for this time of year.

Parts of northwest Vic, western Tas and central and eastern SA could see High fire danger ratings on Tuesday amid the brief burst of warm weather.

While this two-day pulse of warm weather is not going to cause catastrophic fire danger, these spells of early-season heat can help dry out vegetation to create more fuel for fires in the summer months.
