Recently, Grazalema, located in the mountains of Cádiz, has experienced a catastrophic weather event. Meteorologist Nahel Belgherze, who specializes in extreme weather worldwide, referred to the rainfall in this region as “hydrologically absurd.”
Understanding the Rainfall Phenomenon
“Hydrologically absurd”? Absolutely. Grazalema has recorded an astonishing accumulation of over 2,000 mm of rain in just the last 20 days, surpassing the average annual rainfall and occurring at the outset of February. This unprecedented amount of precipitation contributes to severe flooding and instability in the area.
Spain’s Reservoirs Under Pressure
Such heavy rainfall has not only impacted Grazalema but has also led to Spanish reservoirs holding a staggering 43,341 hm³ of water—5,634 hm³ more than just a week ago. Currently, Spain’s water storage is at an incredible 77.34% of its total capacity. In fact, many reservoirs are still discharging water in anticipation of even more rain.
The Graph: A Visual Representation
What do you see in the graph? The graph illustrates the cumulative rainfall data for the Grazalema station, with additional gray lines showing data from previous years. The unprecedented rain is starkly evident as the curve nearly reaches vertical. It is clear that we are witnessing a remarkable water surge compared to typical years, during which the river levels gradually rise in spring and winter.
Something Unprecedented. This extraordinary situation has compelled the CISC technicians to continue assessing the Grazalema aquifer. The local City Council has stated that residents will only be permitted to return when authorities can assure their safety. Meanwhile, experts from the Geological and Mining Institute of Spain (IGME) remain actively involved in studies.
The Aquifer’s Condition
The aquifer—spanning approximately 18 square kilometers—now faces immense pressure. Authorities are diligently working to eliminate even the slightest risk of collapse prior to allowing residents to return. The Junta de Andalucía has increasingly warned that these evaluations could take considerable time.
With high levels of rain and ongoing investigations into the geological stability of Grazalema, the future remains uncertain for its residents. The community, deeply integrated with the natural landscape, now faces dire challenges exacerbated by climate phenomena.
