In another part of the world, a major city was left in darkness last week after strong winds damaged the city’s power grid, with falling trees knocking out electricity cables. The weather conditions also led to major travel disruption at a major airport, where numerous air services were grounded.

A particular form of fog, which usually lasts for only a few days, has been remarkably widespread and long-lasting this year, keeping temperatures at a key transport hub below 8C for more than a week – the longest such streak in more than three decades. The prolonged fog has been driven by unprecedented autumn precipitation that resulted in the ground waterlogged.

Severe Weather Delivers Snow to Holiday Islands

Turning to Spain, a weather system has brought heavy rainfall, powerful gales and even snowfall to a set of islands – weather many would not connect with this popular holiday destination. While snow is not unheard of at elevated areas, the storm delivered some of the deepest snow depths since 2016 to a national park, forcing its closure.

Alongside the snow, fierce winds from the north buffeted the island chain, with wind gusts exceeding 50mph recorded on multiple islands. The influence of the storm is expected to diminish this week with more seasonal weather taking hold.
