Tempest Claudia Brings More Flooding to the Portuguese nation and Spain

The Iberian nations are again dealing with the consequences of widespread flooding in the wake of Storm Claudia brought torrential downpours and powerful gusts the previous week.

Claudia's Origin and Path

The storm system developed from a low-pressure zone that had beforehand driven unseasonably early cold and snowy conditions through the eastern sectors of Canada and the American north-east at the start of November.

Claudia moved eastward across the Atlantic Ocean during the second weekend of November before slowing and stalling to the north-west of the Iberian peninsula, snared in a dip of an progressively more wavy air current.

Consequences for Iberia

Galicia in north-west Spain was initially impacted, with three to six inches of rain pouring down along its west coast in just one full day up to Wednesday night as a slow-moving band of rain crawled across the western areas of the Iberian peninsula.

Additional rainfall and electrical storms on the following Thursday led to floods to parts of Portugal where an older couple perished in Lisbon after floodwaters from the swollen Tagus entered their home as they were asleep.

Unsettled atmospheric states lasted through the weekend, with a tornado tearing through a campsite and a close-by inn in Albufeira in the Algarve region on Saturday, claiming the life of an elderly British lady and harming 28 individuals.

Wider Effects across Europe

The storm produced broader repercussions across the western European nations. By pulling tropical air from the subtropics, the system contributed to thermometers climbing in France's south-west to 29.8C (85.6F), the country's highest recorded autumn temperature.

By Friday, this hot and moist atmospheric body clashed with a chilly atmospheric body across the northern regions of the continent, forming a precipitation zone stretching from the west of Ireland to Russia.

In the Britain, this stationary front of rain delivered very high rainfall totals, leading to major inundations in the Welsh region.

As this weather phenomenon loses strength at the start of the week, the chilly atmospheric system will advance southward, providing the continent its initial glimpse of winter.

Related Incidents in California

The Golden State experienced a plume of tropical moisture last week, bringing torrential rain and high-velocity gusts that provoked sudden inundations and landslides in regions affected by blazes in the recent past.

In excess of 50 millimetres of rain was recorded in southern California on last Friday, with a further 50mm widely across the state on Saturday last.

Over four inches of rain fell over coastal areas of Southern CA in aggregate, hitting 200mm overall in areas of elevated terrain.

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

Burn scar areas including Palisades and Altadena region experienced the most severe the rapid inundations and earth movements, leading to evacuations.

In other parts of the state, a man in his seventies lost his life after his car was carried away from a submerged bridge, and a child of seven years and her father were swept into the ocean by powerful waves on the the state's central shoreline.
