Tempest Claudia Delivers Additional Flooding to Portugal and the Spanish territory

Portugal and Spain are once more battling the aftermath of significant flooding in the wake of Tempest Claudia delivered heavy rain and powerful gusts the previous week.

Claudia's Genesis and Journey

This weather system originated from an area of low pressure that had previously caused early season cold and snowy conditions through the eastern regions of the Canadian territory and the north-eastern US during the beginning of the eleventh month.

Claudia journeyed east across the Atlantic during the second weekend of November before losing momentum and stopping to the north-west of the Iberian peninsula, caught in the trough of an progressively more wavy atmospheric river.

Impact on Spain and Portugal

The northwestern Spanish region of Galicia was hit first, with 80-150mm of rain pouring down along its western coastline in just a single day up to Wednesday evening as a slow-moving band of rain pushed across the western areas of the Iberian peninsula.

Additional rainfall and electrical storms on the following Thursday caused inundations to Portuguese localities where an elderly couple died in the capital Lisbon after water from the overflowing Tagus River invaded their residence as they rested.

Unsettled atmospheric states continued into the weekend, with a tornado tearing through a outdoor lodging area and a adjacent hotel in Albufeira in the south in southern Portugal on Saturday, fatally injuring an British woman aged 85 and wounding 28 individuals.

Broader Impacts across the European continent

Claudia had wider effects across Europe's western part. By siphoning heated air from the subtropical zones, the system helped temperatures in southwestern France to nearly 30 degrees Celsius, the nation's all-time high autumn temperature.

By the following Friday, this hot and moist atmospheric body collided with a chilly atmospheric body across the northern areas of the continent, creating a rainfall belt stretching from Ireland's west to Russia.

In the UK, this halting system of rain produced record-breaking rain accumulations, leading to severe flooding in the Welsh region.

As the storm loses strength early this week, the cold air mass will move towards the south, giving Europe its first taste of the winter season.

Related Incidents in the state of California

The Golden State encountered a plume of tropical moisture last week, causing heavy rain and strong winds that led to flash flooding and mudslides in zones affected by forest fires earlier this year.

Over two inches of rain was recorded in California's southern part on last Friday, with a additional two inches across extensive areas of California on Saturday last.

More than 100mm of rain was deposited on shoreline regions of southern California in total, attaining 200mm overall in areas of elevated terrain.

This meteorological feature is a concentrated stream of hot, humid air stemming from the tropics or subtropics.

Regions previously burned including Pacific Palisades and Altadena region suffered the most severe the sudden floods and earth movements, leading to evacuations.

Across California, a elderly male passed away after his vehicle was swept off a submerged bridge, and a young girl aged seven and her father were dragged into the sea by big swells on the California's Central Coast.
