Tempest Claudia Brings Additional Flooding to the Portuguese nation and the Spanish territory

Portugal and Spain are once more recovering from extensive flooding following Storm Claudia delivered torrential downpours and strong winds the previous week.

Claudia's Genesis and Journey

This meteorological event formed from a low-pressure zone that had previously ushered in early season cold and snowy conditions through the eastern sectors of Canada and the American north-east during the beginning of the eleventh month.

The system journeyed east across the Atlantic in the middle of the second week of November before slowing and stalling to the northwestern area of the Iberian region, snared in a dip of an progressively more wavy atmospheric river.

Impact on Iberia

Spain's Galicia area in the northwest was initially impacted, with three to six inches of rain falling along its western coastline in just a single day up to Wednesday night as a leisurely moving system of rain pushed across western parts of the peninsula.

More downpours and stormy weather on Thursday brought flooding to areas in Portugal where an elderly couple perished in Lisbon after rising waters from the bursting Tagus River invaded their residence as they slept.

Tempestuous weather lasted through the weekend, with a violent whirlwind tearing through a campsite and a nearby hotel in Albufeira in the south in the Algarve region on Saturday, killing an elderly British lady and injuring 28 individuals.

Wider Effects across the European continent

This system triggered more extensive impacts across Europe's western part. By pulling tropical air from the subtropics, the system assisted in raising temperatures in south-west France to 29.8C (85.6F), the country's highest recorded autumn temperature.

By last Friday, this hot and moist atmospheric body met a frigid air system across the northern areas of Europe, generating a rainfall belt stretching from Ireland's west to Russia.

In the Britain, this stalling band of rain brought exceptionally large precipitation amounts, resulting in significant waterlogging in the Welsh region.

As the storm continues to weaken at the start of the week, the chilly atmospheric system will advance southward, giving Europe its first taste of winter.

Parallel Events in California

The Golden State encountered a so-called atmospheric river recently, causing intense precipitation and powerful winds that led to rapid flooding and mudslides in regions scarred by forest fires in the recent past.

Over two inches of rain was recorded in the southern region of the state on Friday, with a another 50 millimetres broadly over the state on Saturday.

In excess of 100 millimetres of rain was deposited on coastal areas of the state's south in all, reaching a full 200 millimetres in areas of elevated terrain.

This meteorological feature is a narrow band of hot, humid air originating from the equatorial or near-equatorial zones.

Regions previously burned including Palisades and the town of Altadena suffered the most severe the sudden floods and landslides, leading to evacuations.

Across California, a man in his seventies lost his life after his car was washed off a flooded bridge, and a seven-year-old girl and her dad were swept into the ocean by large waves on the Central Coast.
