Global Climatic Events Trigger Disruption

Elsewhere, a metropolis was plunged into darkness recently after strong gusts compromised the city’s electrical network, with toppled trees bringing down power lines. The weather conditions also led to significant travel disruption at a major airport, where numerous air services were cancelled.

A particular form of low cloud, which usually lingers for only a short time, has been remarkably extensive and persistent this year, holding the mercury at a key transport hub under 8C for more than a week – the longest such streak in more than three decades. The prolonged haze has been fuelled by unprecedented autumn precipitation that resulted in the ground waterlogged.

• Key Factor: Record autumn rainfall saturated the soil.
• Result: Prolonged and dense mist development.
• Effect: Thermal readings stayed unseasonably low for an lengthy time.

Storm Brings Snow to Tourist Destination

And in another country, a powerful storm has brought intense rainfall, powerful gales and even snowfall to a group of islands – weather many would not associate with this favored holiday destination. While wintry precipitation is not unheard of at higher ground, the storm delivered some of the heaviest snow depths in 2016 to a national park, compelling its temporary shutdown.

In addition to the snow, fierce winds from the north buffeted the island chain, with wind gusts reaching 50mph recorded on several locations. The effect of the storm is expected to ease this week with more seasonal conditions returning.
