This post examines a sequence of powerful storms that battered the western Mediterranean over several weeks, bringing catastrophic floods, structural damage, and loss of life in Spain, Portugal, and Morocco. Drawing on on-the-ground reports and attribution studies, it also explains how climate warming is shaping these extreme events and what that means for resilience, warning systems, and policy.
What happened: storms, impacts, and human stories
Across the region, a relentless series of storms overwhelmed communities and infrastructure. In Grazalema, Spain—the country’s wettest town—a year’s worth of rain fell in just two weeks.
This inundated the karst aquifer and drove large-scale evacuations as water poured into homes through floors, walls, and even electrical sockets. In Portugal’s Leiria region, Storm Kristin generated winds up to 109 mph at Monte Real airbase before instruments failed.
This caused power outages and communications disruptions and placed residents at risk in collapsing structures and fallen trees. In Morocco’s Safi, flash floods and “explosive mud waves” swept through narrow medina streets and pottery souks.
These events contributed to dozens of storm fatalities, especially in confined urban cores. Scientists note that atmospheric changes have produced 16 rapid-fire storms this season.
While attribution work is still evolving, multiple studies point to climate heating as a key intensifier of these events. Climate Central found that a concurrent marine heatwave made early-February storms ten times more likely.
A World Weather Attribution analysis linked carbon pollution to stronger rains and worse flooding. Observational data show the most extreme rainfall days in Spain, Portugal, and Morocco now release about one-third more water than in the 1950s.
What scientists say about climate drivers and risk
From the perspective of decades of climate and risk research, the current sequence underscores how warming oceans, atmospheric dynamics, and land-surface responses interact to fuel extreme rainfall and flooding. The regional pattern—frequent, intense storm events in the western Mediterranean—appears increasingly likely as long-term trends push higher moisture content into storm systems and alter storm tracks.
Key factors cited by researchers include:
- Rapid-fire storm sequences: An unusually high number (16) of strong storms in a single season point to a changing storm regime.
- Marine heatwaves: Warmer ocean conditions amplified storm intensity and precipitation potential, as shown by Climate Central’s analysis.
- Global carbon pollution: Attribution studies link fossil-fuel–driven warming to heavier rains and more severe floods.
Regional responses and gaps in preparedness
Responses varied by location, revealing strengths to build on and gaps to address. In Grazalema, authorities executed a well-coordinated evacuation in cooperation with neighboring Ronda, earning praise for timely action.
In Portugal, some residents and experts argued that warnings did not generate sufficient public alarm or actionable guidance, highlighting challenges in risk communication and community readiness. Across Europe and North Africa, the storms exposed broad gaps in preparedness and adaptation.
This underscores the need for enhanced early warning, robust infrastructure, and better land-use planning to reduce exposure in vulnerable areas.
What this means for policy, resilience, and adaptation
For policymakers and practitioners, the events call for a multi-pronged approach to reduce risk in a warming climate. This includes improving forecast accuracy and communication.
Strengthening evacuation models and routes is also important. Investing in flood-prone infrastructure and building codes tailored to extreme rainfall and mudflow hazards is essential.
Adaptation must be integrated with mitigation—cutting carbon emissions while expanding resilient systems that can withstand harder rain, faster floods, and more intense heatwaves.
The lessons from Grazalema and its counterparts should guide future planning. Emphasizing community engagement, transparency in warnings, and regional cooperation will help anticipate and respond to similarly severe storms.
