Scorching conditions and raging wildfires have devastated the dry landscape of Western Australia. As temperatures expected to persist soaring above 40C (104F) over the next few days, a major heatwave warning has been declared across much of the southwestern region.

Widespread Extreme Heat Alerts Throughout the Region

These conditions come after recent bushfires in New South Wales, which resulted in the destruction of properties and loss of life. Intense heat alerts have additionally been issued for the coming days in parts of South Australia and NSW, as a ridge of high pressure moves to the east, bringing blazing sunshine to a broad swath of the area.

The combination of extremely dry vegetation and relentless heat creates a dangerous scenario for firefighters.

Worldwide Climatic Events Trigger Disruption

In another part of the world, a metropolis was left in blackout last week after strong winds compromised the city’s electrical network, with falling trees knocking out electricity cables. The weather conditions also caused major transport delays at a major airport, where numerous air services were cancelled. Severe damage to power systems is anticipated to cause further issues as service providers work urgently to restore power to more than 1 million residents.

Atypical Fog Blankets Typically Clear Area

Meanwhile, a valley famed for its sunny weather and abundant sunshine has endured one of its grayest and most overcast periods on recorded history. A specific type of fog, which typically lingers for only a short time, has been remarkably widespread and long-lasting this year, holding the mercury at a key transport hub below 8C for more than a week – the most prolonged period in over three decades. The prolonged fog has been driven by exceptional fall rainfall that resulted in the ground waterlogged.

• Primary Driver: Exceptional fall rains soaked the soil.
• Outcome: Extended and thick fog development.
• Impact: Thermal readings remained below average for an extended period.

Severe Weather Brings Wintry Weather to Tourist Islands

Turning to Spain, a powerful storm has ushered in intense rain, strong gales and even snowfall to a group of islands – conditions many would not associate with this popular holiday destination. While snow is not unheard of at elevated areas, the storm brought some of the deepest snow depths since 2016 to a national park, compelling its temporary shutdown.

In addition to the snowfall, strong northerly winds swept across the archipelago, with gusts reaching 50mph observed on multiple locations. The influence of the storm is forecast to ease this week with more typical conditions taking hold.
