Tempest Claudia Delivers More Flooding to the Portuguese nation and Spain
The Iberian nations are again recovering from significant inundation after Storm Claudia unleashed heavy rain and powerful gusts over the past seven days.
The Storm's Genesis and Journey
The storm system developed from an area of low pressure that had beforehand caused unseasonably early cold and snowy conditions through eastern parts of the Canadian territory and the American north-east during the beginning of the eleventh month.
The system tracked eastwards across the Atlantic Ocean during the second weekend 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 Spain and Portugal
Spain's Galicia area in the northwest was the first affected, with 80-150mm of rain pouring down along its Atlantic coast in just a single day up to the evening of Wednesday as a leisurely moving system of rain drifted across the western areas of the peninsula.
Additional rainfall and electrical storms on the following Thursday caused inundations to parts of Portugal where an older couple died in Lisbon after water from the overflowing Tagus River flooded their dwelling as they slept.
Tempestuous weather lasted through the weekend, with a tornado devastating a outdoor lodging area and a adjacent hotel in the town of Albufeira in southern Portugal on Saturday, fatally injuring an British woman aged 85 and injuring two dozen and eight persons.
Extended Consequences across the European continent
The storm produced wider effects across Europe's western part. By pulling tropical air from the subtropical zones, the system helped temperatures in France's south-west to 85.6 degrees Fahrenheit, the nation's all-time high autumn temperature.
By Friday, this tropical air mass collided with a cold air mass across the northern areas of Europe, forming a band of rain stretching from western Ireland to the Russian Federation.
In the Britain, this stationary front of rain brought exceptionally large precipitation amounts, leading to major inundations in the principality of Wales.
As Claudia progressively weakens in the coming days, the chilly atmospheric system will advance southward, providing the continent its initial glimpse of winter.
Related Incidents in California, USA
California encountered an "atmospheric river" the previous week, delivering torrential rain and strong winds that led to sudden inundations and mudslides in regions impacted by wildfires in the recent past.
More than 50mm of rain fell in southern California on last Friday, with a additional two inches widely across the state on Saturday last.
Over four inches of rain was deposited on coastal parts of Southern CA in total, hitting eight inches in total in spots on high ground.
An atmospheric river is a narrow band of hot, humid air originating from the equatorial or near-equatorial zones.
Regions previously burned including the Pacific Palisades area and Altadena experienced the most severe the sudden floods and landslides, prompting evacuations.
In other parts of the state, a elderly male lost his life after his vehicle was washed off a inundated overpass, and a seven-year-old girl and her parent were dragged into the sea by big swells on the California's Central Coast.
