Scorching conditions and intense bushfires have swept through the parched landscape of Western Australia. With mercury levels expected to persist soaring above 40C (104F) over the next few days, a major alert for extreme heat has been issued across much of the south-west.

Widespread Extreme Heat Warnings Throughout Multiple States

These conditions come after this month's bushfires in another state, which caused the destruction of properties and loss of life. Severe heatwave warnings have additionally been activated for the coming days in parts of SA and New South Wales, as a ridge of high pressure shifts to the east, bringing intense heat to a broad swath of the region.

The mix of tinder-dry land and relentless heat presents a volatile scenario for firefighters.

Worldwide Climatic Events Cause Disruption

Elsewhere, a metropolis was plunged into blackout recently after strong winds damaged the city’s power grid, with toppled trees bringing down power lines. The stormy weather also caused significant transport delays at a key airport, where hundreds of air services were cancelled. Substantial damage to electrical infrastructure is anticipated to create ongoing issues as utility companies work urgently to restore power to over 1 million residents.

Atypical Fog Blankets Sunny Area

At the same time, a valley known for its sunny weather and plentiful sunshine has endured one of its grayest and most overcast periods on record. A specific type of fog, which usually lasts for only a few days, has been remarkably extensive and long-lasting this year, holding temperatures at a key transport hub under 8C for more than a week – the most prolonged period in over three decades. The prolonged fog has been driven by unprecedented autumn rainfall that resulted in soils saturated.

• Primary Driver: Exceptional autumn rainfall saturated the soil.
• Result: Prolonged and thick fog development.
• Effect: Thermal readings remained unseasonably low for an extended time.

Severe Weather Brings Wintry Weather to Holiday Islands

And in Spain, a weather system has brought heavy rainfall, powerful gales and even snow to a group of islands – conditions many would not associate with this popular tourist spot. While wintry precipitation is not unheard of at elevated areas, the storm delivered some of the deepest accumulations since 2016 to a national park, compelling its closure.

In addition to the snow, fierce winds from the north swept across the island chain, with gusts reaching 50mph observed on several islands. The effect of the storm is expected to ease this week with more typical conditions taking hold.
