Smoke, snow and storms.

These have been the weather conditions seen in Australia within the first 16 days of our 2019 summer.

Indeed, weather extremes have been ever the extreme this December – ranging from hail falling to hazardous air.

And the severity is only set to continue, as ferocious fires continue to blaze in NSW and Western Australia. A heatwave is also forecast to deliver extreme temperatures to South Australia, NSW and Victoria this week.

Here are just 16 photos from around Australia that depict the first 16 days of summer this year.

Today's the first day of #summer but you might be better to grab the #snow, not the water skis! Snow is forecast for the next 3 days for the #alps, as low as 1200 metres on Monday. Stay safe if you are in the high country by following the alpine forecast: https://t.co/0CFTjppmVF pic.twitter.com/36GlkT02qN

A stunning #sunrise in #Darwin this morning due to some cloud from overnight storms. Unfortunately, heatwave conditions will continue across most of the #NT this week. There will be some relief for #AliceSprings later this week. See your forecasts at https://t.co/CWBIqauWEY pic.twitter.com/Gaui61uXkx
