Scorching conditions and raging bushfires have swept through the dry landscape of Western Australia. With mercury levels forecast to persist climbing above 40C (104F) over the next few days, a major heatwave warning has been declared across a large portion of the south-west.

Broad Heatwave Warnings Across Multiple States

This situation follow recent fires in another state, which caused the loss of properties and fatalities. Intense heatwave warnings have also been issued for the coming days in parts of South Australia and New South Wales, as a ridge of atmospheric pressure moves eastward, bringing blazing heat to a broad swath of the region.

The mix of extremely dry land and relentless high temperatures creates a volatile situation for emergency crews.

Worldwide Climatic Events Cause Chaos

In another part of the world, a major city was left in blackout recently after strong winds compromised the city’s power grid, with falling trees knocking out power lines. The weather conditions also caused major travel disruption at a major airport, where numerous flights were cancelled. Substantial impact on power systems is anticipated to create further issues as service providers scramble to reconnect electricity to over 1 million inhabitants.

Unusual Mist Blankets Sunny Area

At the same time, a region known for its sunny weather and abundant sunshine has endured one of its grayest and most overcast weeks on record. A specific type of fog, which typically lingers for only a few days, has been unusually extensive and long-lasting this year, keeping the mercury at a major airport under 8C for more than a week – the longest such streak in more than three decades. The prolonged haze has been driven by unprecedented autumn precipitation that left the ground saturated.

• Primary Driver: Record autumn rainfall saturated the ground.
• Result: Extended and dense mist development.
• Impact: Temperatures remained unseasonably low for an extended time.

Severe Weather Delivers Wintry Weather to Holiday Islands

And in another country, a weather system has ushered in intense rain, powerful gales and even snowfall to a set of islands – conditions many would not associate with this favored tourist spot. While snow is not unknown at elevated areas, the storm brought some of the heaviest accumulations in 2016 to a national park, forcing its temporary shutdown.

Alongside the snow, fierce winds from the north swept across the island chain, with wind gusts reaching 50mph observed on multiple islands. The effect of the weather event is forecast to diminish this week with more typical weather returning.
