Extratropical cyclone in Uruguay 2005: 20 years since the historic disaster
The 2005 extratropical cyclone in Uruguay turns 20 this August 23rd. For many Uruguayans, that night has been etched as one of the harshest and most traumatic climate-related experiences. With gusts of up to 200 km/h, the phenomenon entered through Kiyú, in San José, advanced toward Canelones, and struck Montevideo, Colonia, and Maldonado, leaving a toll of dead, injured, and displaced thousands.
Historical context of the cyclone
In Uruguay, we're accustomed to strong storms, especially in winter. However, what happened in 2005 was no ordinary storm. It was an extratropical cyclone , a type of phenomenon more common in other latitudes, which struck with an intensity rarely seen in the Río de la Plata.
Technicians from the Uruguayan Meteorological Institute had issued warnings, but the actual magnitude of the event exceeded any forecasts. The cyclone moved from the southwest to the center-south in just a few hours, with a disproportionate impact due to the population density of the affected departments. In total, 70% of Uruguayans felt the storm's effects directly .
Human impact of the extratropical cyclone in Uruguay 2005
The highest cost was human. The cyclone left ten dead across the country. There were also hundreds injured, mainly from falling objects and structural collapse .
More than a thousand people were displaced from their homes, most of them poor families who lost their roofs or saw their houses completely destroyed . Many of them spent weeks in gyms or makeshift shelters. Residents of Montevideo remember sleeping on mats, sharing mate and candles, not knowing when they would have electricity or water again.
The plight of the displaced was one of the elements that most impacted public opinion . In a country accustomed to storms, no one imagined that such a scale of uprooting could occur in the 21st century.
Material and infrastructure damage
The 2005 extratropical cyclone in Uruguay not only affected people, but also public and private infrastructure.
-
Thousands of homes were left roofless.
-
Entire businesses lost merchandise and structure.
-
Centuries-old trees and UTE columns collapsed.
-
In Montevideo, part of its flag fell from Plaza de la Bandera
-
In Punta del Este, several sailboats ended up stranded or adrift.
Basic services were disrupted for days. Hundreds of thousands of users were without electricity and drinking water. UTE and OSE crews worked tirelessly, but the magnitude of the disaster made recovery slow.
The State's response in 2005
The government of the time reacted with the tools at its disposal, although the magnitude of the cyclone exposed many shortcomings. Makeshift shelters in gymnasiums demonstrated the limitations of the emergency infrastructure.
As for warnings, meteorologists had predicted the arrival of a strong storm, but not as violent as the storm that ultimately unfolded. Communication to the population was insufficient, leaving thousands of Uruguayans unprepared for what was coming.
Lessons and changes after the cyclone
2005 extratropical cyclone in Uruguay made anything clear , it was the need for a more robust emergency management system.
That event was instrumental in strengthening the National Emergency System (Sinae) . From then on, stricter protocols were established, investment in equipment was made, and coordination between ministries, municipalities, and public agencies was improved.
Today, 20 years later, Uruguay has clearer and more detailed early warnings, evacuation plans, coordination with municipal governments, and a more effective communication system with citizens.
Twenty years later: memory and resilience
This year's anniversary invites us to remember and reflect. The 2005 extratropical cyclone in Uruguay marked a turning point not only in national meteorology but also in public awareness.
Residents of San José and Canelones still recount their sleepless night, nursing what little they had left or taking refuge in relatives' homes. Others recall the long lines to get water or charge cell phones in the few places with power.
In a context of climate change , experts point out that large-scale phenomena could be repeated. Therefore, looking back is not just about memory; it's also about preparation. The memory of 20 years ago becomes a warning for new generations.
Conclusion
The 2005 extratropical cyclone in Uruguay remains, two decades later, a reminder of the country's vulnerability to extreme events. It is also a testament to people's resilience and institutional learning.
