Extreme heat and raging wildfires have devastated the dry landscape of Western Australia. With temperatures expected to continue soaring above 40C (104F) over the next few days, a major heatwave warning has been issued across much of the southwestern region.

Broad Heatwave Warnings Across the Region

These conditions follow recent bushfires in another state, which resulted in the loss of homes and loss of life. Intense heat alerts have additionally been issued for the coming days in areas within SA and NSW, as a system of high pressure moves eastward, delivering intense sunshine to much of the area.

The mix of extremely dry land and relentless high temperatures creates a dangerous situation for firefighters.

Global Climatic Events Trigger Chaos

Elsewhere, a metropolis was left in darkness recently after powerful gusts compromised the city’s power grid, with toppled trees bringing down electricity cables. The stormy weather also led to significant transport delays at a major airport, where numerous air services were cancelled. Severe damage to power systems is expected to create ongoing problems as utility companies scramble to reconnect electricity to more than 1 million residents.

Atypical Mist Blankets Typically Clear Region

At the same time, a valley famed for its sunny weather and plentiful sunlight has endured one of its dullest and foggiest periods on record. A particular form of fog, which typically lasts for only a short time, has been remarkably extensive and long-lasting this year, holding temperatures at a key transport hub below 8C for over a week – the most prolonged period in over three decades. The prolonged haze has been fuelled by exceptional autumn rainfall that resulted in soils waterlogged.

• Key Factor: Exceptional autumn rainfall saturated the ground.
• Outcome: Prolonged and dense mist formation.
• Impact: Thermal readings stayed unseasonably low for an extended period.

Storm Delivers Wintry Weather to Holiday Islands

And in another country, a weather system has ushered in intense rain, powerful winds and even snow to a group of islands – conditions many would not connect with this favored tourist spot. While snow is not unknown at higher ground, the storm brought some of the deepest accumulations in 2016 to a national park, forcing its closure.

In addition to the snow, fierce winds from the north swept across the island chain, with wind gusts exceeding 50mph recorded on multiple islands. The influence of the weather event is expected to ease this week with more typical conditions taking hold.
