Storm Claudia Delivers More Flooding to Portugal and Spain

Portugal and Spain are once more recovering from extensive flooding in the wake of Storm Claudia unleashed torrential downpours and powerful gusts over the past seven days.

Claudia's Genesis and Journey

This weather system developed from a low-pressure zone that had previously ushered in early season chilly and snowy weather through eastern parts of the Canadian territory and the north-eastern United States during the beginning of the eleventh month.

This storm moved eastward across the Atlantic in the middle of the second week of November before losing momentum and stopping to the northwestern area of the Iberian region, trapped within a trough of an increasingly amplified air current.

Effects in Spain and Portugal

The northwestern Spanish region of Galicia was initially impacted, with three to six inches of rain pouring down along its western coastline in just 24 hours up to the evening of Wednesday as a sluggish front of rain crawled across the western sectors of the region.

Additional rainfall and electrical storms on the following Thursday brought flooding to parts of Portugal where an elderly couple perished in Lisbon after water from the overflowing Tagus River invaded their residence as they rested.

Unsettled atmospheric states continued into the weekend, with a twister tearing through a campsite and a nearby hotel in Albufeira in the south in the Algarve region on the weekend's Saturday, fatally injuring an British woman aged 85 and injuring two dozen and eight persons.

Extended Consequences across the European continent

Claudia had wider effects across the western European nations. By siphoning heated air from the subtropics, the system assisted in raising temperatures in southwestern France to 85.6 degrees Fahrenheit, the country's highest recorded November temperature.

By Friday, this hot and moist atmospheric body met a cold air mass across more northern parts of Europe, creating a band of rain running from Ireland's west to the Russian Federation.

In the Britain, this stalling band of rain brought record-breaking rain accumulations, resulting in major inundations in the Welsh region.

As the storm progressively weakens at the start of the week, the frigid air will advance southward, providing the continent its initial glimpse of colder weather.

Simultaneous Occurrences in California, USA

The Golden State underwent a so-called atmospheric river recently, bringing torrential rain and high-velocity gusts that provoked rapid flooding and debris flows in areas affected by wildfires earlier this year.

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

Over four inches of rain fell over coastal areas of Southern CA in all, reaching 200mm overall in spots on high ground.

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

Regions previously burned including the Pacific Palisades area and Altadena experienced the worst of the flash flooding and earth movements, leading to evacuations.

Across California, a elderly male died after his automobile was washed off a inundated overpass, and a young girl aged seven and her parent were dragged into the Pacific by big swells on the Central Coast.
