In a dramatic turn of events, Spain is bracing for an extreme weather phenomenon known as a gota fría or “cold drop” this week. According to meteorologists, the eastern regions of the country, particularly Valencia, Catalonia, Murcia, and eastern Andalucía, could bear the brunt of this atmospheric assault, with some areas potentially receiving over 150mm of rain within a mere 24 hours on Tuesday – an astonishing seven times the typical average for the entire month.
Gibraltar, too, finds itself in the crosshairs of this meteorological menace, with forecasts suggesting rainfall totals exceeding 40mm. But what exactly is a gota fría, and why does it pose such a significant threat to these regions?
The Science Behind the Storm
A gota fría, while poetically named, is a complex and often unpredictable weather event. Officially known as a “depresión aislada en niveles altos” or “DANA” to Spanish meteorologists, it translates to “isolated depression at high altitudes” in English. This phenomenon occurs when a pocket of cold air becomes detached from the main jet stream and drifts over the warm waters of the Mediterranean Sea.
The stark contrast between the cold air aloft and the warm, moisture-laden air rising from the sea creates a cauldron of atmospheric instability. As the warm air rapidly ascends, it condenses into towering cumulonimbus clouds, setting the stage for an onslaught of heavy rain, hail, thunderstorms, and potentially severe flooding.
The Unpredictable Nature of Gota Frías
While the broad strokes of a gota fría event can be forecasted, pinpointing the exact locations that will be most severely impacted is a daunting challenge for even the most seasoned meteorologists. These storms are notoriously localized, with rainfall totals varying wildly over short distances.
Gota frías are some of the most dynamic and difficult weather events to predict. You can have one town experiencing catastrophic flooding while a neighboring village just a few kilometers away remains relatively unscathed.

This unpredictability makes it all the more crucial for residents in the potentially affected regions to stay informed and heed any warnings or evacuation orders issued by local authorities. Even a seemingly minor miscalculation in the storm’s trajectory could have profound consequences.
A History of Destruction
Spain is no stranger to the devastation wrought by gota frías. In September 2019, a particularly severe cold drop event unleashed torrential rainfall across the southeastern regions of the country, leading to catastrophic flooding that claimed the lives of six people and caused widespread damage to infrastructure and agriculture.
More recently, in August 2023, another gota fría battered the Costa Blanca region, inundating streets, homes, and businesses. The resort town of Benidorm saw its beachfront promenade transformed into a raging river, while the city of Orihuela experienced its worst flooding in over a century.
It was like something out of a disaster movie. Cars were being swept away like toys, and people were clinging to trees and lamp posts to avoid being carried off by the floodwaters.

Preparing for the Worst
As the gota fría bears down on eastern Spain, authorities are scrambling to prepare for the potential fallout. Emergency services have been placed on high alert, with additional personnel and resources being deployed to the regions most likely to be affected.
- Sandbags are being distributed to help fortify homes and businesses against floodwaters
- Drainage systems are being cleared of debris to prevent blockages and minimize the risk of flash flooding
- Residents in low-lying areas are being urged to have emergency kits ready and to familiarize themselves with evacuation routes
Schools and universities in Valencia and Murcia have preemptively cancelled classes for Tuesday and Wednesday, while many businesses have opted to close their doors until the storm passes. The Spanish military has also been placed on standby, ready to assist with rescue and relief efforts if necessary.
The Climate Change Connection
As the Mediterranean region contends with yet another potentially devastating gota fría, some experts are pointing to climate change as a contributing factor to the increased frequency and intensity of these events. Rising sea surface temperatures in the Mediterranean, a consequence of global warming, provide more fuel for these storms, allowing them to grow stronger and dump more rain.
While gota frías have always been a part of the Mediterranean climate, there’s growing evidence to suggest that climate change is making these events more common and more severe. It’s a trend that we can’t afford to ignore.

As Spain braces for the imminent arrival of this latest gota fría, it serves as a stark reminder of the ever-present threat posed by these capricious Mediterranean storms. In the face of an increasingly volatile climate, it’s a threat that is likely to only grow more pronounced in the years to come.
For now, all eyes are on the skies over eastern Spain, as residents, emergency responders, and the nation as a whole hold their collective breath, hoping that the cold drop will prove more merciful than its predecessors. Only time will tell if those hopes will be realized, or if the gota fría will once again leave a trail of destruction in its wake.
