While summer is still more than a month away, fire crews have had a taste of things to come, being called to at least 17 fires across South Australia in the past 24 hours.

As the temperature almost reached 34 degrees in Adelaide, a blaze at MacDonald Park, in Adelaide’s outer northern suburbs, came within metres of a home.

The fire began after a spark jumped out of a metal drum being used to burn-off rubbish and ignited nearby grass.

It spread quickly and tore through several glasshouses, destroying the flower crops inside.

The flames crept to within just two metres of a nearby home before Country Fire Service (CFS) crews arrived and were able to save it.

Total damage to the rest of the property is estimated at about $100,000.

CFS crews were called out to about 17 fires in the past 24 hours.

Gerry Thomson from the CFS says it is a warning of things to come.
