Extreme heat and raging bushfires have swept through the parched landscape of Western Australia. With mercury levels expected to persist soaring above 40C (104F) over the coming days, a severe alert for extreme heat has been declared across a large portion of the south-west.

Widespread Extreme Heat Warnings Throughout Multiple States

This situation follow this month's bushfires in another state, which caused the loss of homes and fatalities. Intense heat alerts have also been activated for later this week in parts of SA and NSW, as a system of atmospheric pressure moves eastward, delivering intense heat to much of the region.

The mix of tinder-dry vegetation and relentless heat creates a dangerous scenario for emergency crews.

Worldwide Climatic Events Cause Chaos

In another part of the world, a metropolis was left in darkness recently after powerful gusts compromised the city’s power grid, with falling trees bringing down power lines. The weather conditions also caused major transport delays at a key airport, where numerous flights were cancelled. Substantial impact on power systems is anticipated to create ongoing issues as utility companies work urgently to restore power to more than 1 million inhabitants.

Unusual Mist Blankets Sunny Region

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 low cloud, which typically lingers for only a short time, has been unusually widespread and long-lasting this year, keeping temperatures at a major airport below 8C for more than a week – the longest such streak in more than three decades. The prolonged haze has been driven by exceptional autumn precipitation that resulted in the ground waterlogged.

• Key Factor: Record autumn rainfall saturated the ground.
• Outcome: Extended and thick fog formation.
• Effect: Thermal readings stayed unseasonably low for an lengthy time.

Severe Weather Delivers Wintry Weather to Holiday Destination

And in another country, a powerful storm has brought intense rainfall, powerful gales and even snowfall to a set of islands – conditions many would not connect with this favored tourist spot. While wintry precipitation is not unknown at higher ground, the system delivered some of the deepest snow depths in 2016 to a national park, compelling its temporary shutdown.

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