The Iberian nations are again recovering from extensive flooding after Storm Claudia unleashed torrential downpours and strong winds last week.

Claudia's Genesis and Journey

This weather system developed from an area of low pressure that had earlier caused unseasonably early chilly and snowy weather through the eastern sectors of the Canadian territory and the north-eastern United States at the start of November.

This storm journeyed east across the Atlantic Ocean during the second weekend of November before decelerating and halting to the northwestern area of the Iberian region, trapped within a trough of an progressively more wavy air current.

Consequences for Spain and Portugal

Galicia in north-west Spain was the first affected, with three to six inches of rain falling along its west coast in just a single day up to Wednesday night as a slow-moving band of rain crawled across the western sectors of the peninsula.

More downpours and stormy weather on the following Thursday led to floods to parts of Portugal where an older couple died in the city of Lisbon after water from the overflowing Tagus River flooded their dwelling as they were asleep.

Stormy conditions continued into the weekend, with a twister tearing through a camping ground and a nearby hotel in Albufeira in Portugal's south on Saturday, claiming the life of an 85-year-old British woman and harming 28 individuals.

Broader Impacts across Europe

The storm produced wider effects across Europe's western part. By siphoning heated air from the subtropical zones, the system contributed to thermometers climbing in south-west France to 29.8C (85.6F), the nation's all-time high November temperature.

By Friday, this warm and humid air mass collided with a cold air mass across more northern parts of the continent, generating a rainfall belt extending from western Ireland to the Russian Federation.

In the UK, this halting system of rain brought exceptionally large precipitation amounts, resulting in severe flooding in the Welsh region.

As the storm progressively weakens at the start of the week, the cold air mass will push south, providing the continent its premier experience of the winter season.

Related Incidents in the state of California

The Golden State encountered a plume of tropical moisture recently, bringing heavy rain and high-velocity gusts that resulted in flash flooding and landslides in areas scarred by blazes previously in the year.

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

Over four inches of rain was deposited on shoreline regions of the state's south in all, hitting a full 200 millimetres in spots on high ground.

This meteorological feature is a concentrated stream of tropical, saturated air originating from the tropics or subtropics.

Burn scar areas including Pacific Palisades and Altadena region experienced the most intense the rapid inundations and landslides, forcing residents to flee.

Elsewhere in California, a elderly male passed away after his automobile was swept off a submerged bridge, and a young girl aged seven and her parent were dragged into the ocean by large waves on the California's Central Coast.
