Tempest Claudia Brings More Inundation to the Portuguese nation and the Spanish territory
The Iberian nations are again recovering from significant inundation after Tempest Claudia brought torrential downpours and strong winds last week.
The Storm's Formation and Trajectory
The storm system originated from a region of depressed atmospheric pressure that had beforehand caused unseasonably early chilly and snowy weather through the eastern sectors of Canada and the north-eastern United States during the beginning of the eleventh month.
The system moved eastward across the Atlantic in the middle of the second week of November before decelerating and halting to the northwestern area of the Spanish and Portuguese landmass, snared in a dip of an increasingly amplified jet stream.
Consequences for Iberia
Spain's Galicia area in the northwest was initially impacted, with 80-150mm of rain pouring down along its Atlantic coast in just a single day up to the evening of Wednesday as a slow-moving band of rain drifted across the western areas of the region.
More downpours and stormy weather on the following Thursday caused inundations to parts of Portugal where an elderly couple died in Lisbon after floodwaters from the swollen Tagus flooded their dwelling as they rested.
Tempestuous weather continued into the weekend, with a twister tearing through a camping ground and a adjacent hotel in Albufeira in the south in southern Portugal on Saturday last week, fatally injuring an elderly British lady and wounding 28 individuals.
Extended Consequences across the European continent
This system triggered wider effects across western Europe. By pulling tropical air from the warmer regions, the system helped temperatures in southwestern France to 85.6 degrees Fahrenheit, the country's highest recorded November temperature.
By the following Friday, this hot and moist atmospheric body met a cold air mass across the northern regions of Europe, creating a precipitation zone running from Ireland's west to Russia.
In the UK, this stationary front of rain delivered exceptionally large precipitation amounts, causing major inundations in the principality of Wales.
As Claudia continues to weaken at the start of the week, the frigid air will push south, providing the continent its premier experience of colder weather.
Simultaneous Occurrences in California
California underwent a so-called atmospheric river last week, bringing heavy rain and strong winds that led to sudden inundations and debris flows in regions scarred by wildfires earlier this year.
Over two inches of rain fell in California's southern part on the week's end, with a further 50mm across extensive areas of California on Saturday.
More than 100mm of rain accumulated over coastal parts of southern California in aggregate, attaining 200mm overall in spots on high ground.
This meteorological feature is a narrow band of warm, moist air originating from the equatorial or near-equatorial zones.
Locations with fire damage including the Pacific Palisades area and Altadena region experienced the most severe the flash flooding and landslides, forcing residents to flee.
In other parts of the state, a 71-year-old man passed away after his car was washed off a inundated overpass, and a seven-year-old girl and her parent were dragged into the Pacific by large waves on the Central Coast.
