Scorching conditions and intense bushfires have swept through the parched landscape of Western Australia. As temperatures expected to persist soaring above 40C (104F) over the coming days, a severe alert for extreme heat has been declared across much of the southwestern region.

Widespread Extreme Heat Warnings Throughout the Region

This situation come after recent fires in New South Wales, which caused the destruction of homes and loss of life. Intense heatwave warnings have also been issued for later this week in parts of South Australia and NSW, as a system of high pressure shifts to the east, delivering intense heat to a broad swath of the region.

The mix of extremely dry vegetation and unbroken heat presents a dangerous scenario for emergency crews.

Worldwide Weather Extremes Trigger Disruption

In another part of the world, a major city was plunged into darkness recently after powerful gusts damaged the urban power grid, with toppled trees knocking out electricity cables. The stormy weather also caused major travel disruption at a key airport, where numerous flights were grounded. Severe impact on electrical infrastructure is anticipated to create ongoing problems as service providers scramble to restore power to over 1 million inhabitants.

Unusual Mist Blankets Sunny Region

Meanwhile, a region known for its clear skies and abundant sunlight has experienced one of its grayest and foggiest weeks on record. A particular form of low cloud, which typically lingers for only a short time, has been unusually extensive and long-lasting this year, holding temperatures at a key transport hub under 8C for over a week – the most prolonged period in over three decades. The extended haze has been driven by unprecedented fall rainfall that left soils waterlogged.

• Primary Driver: Exceptional fall rains saturated the ground.
• Result: Extended and dense mist formation.
• Impact: Thermal readings remained below average for an lengthy time.

Storm Delivers Wintry Weather to Holiday Destination

Turning to another country, a weather system has ushered in intense rainfall, strong gales and even snow to a group of islands – weather many would not associate with this favored tourist spot. While wintry precipitation is not unheard of at higher ground, the storm delivered some of the deepest snow depths in 2016 to a protected area, compelling its closure.

Alongside the snow, fierce winds from the north swept across the island chain, with wind gusts reaching 50mph recorded on multiple islands. The influence of the weather event is expected to ease this week with more seasonal weather returning.
