Storm Charles Puts Spain on Alert: Atmospheric River and Landslide Risk 2026

Storm Charles has put Spain on high alert, with an atmospheric river and hurricane-force winds threatening to cause widespread disruption and landslides. The storm, which has already battered the Canary Islands, is now moving into the peninsula, prompting AEMET to issue yellow, orange, and red weather warnings across the country.

What Is Storm Charles and Why Is It Dangerous?

Storm Charles is a powerful low-pressure system that has been fueled by an atmospheric river—a narrow band of moisture that transports large amounts of water vapor from the tropics. This phenomenon can produce extreme rainfall and strong winds, making it a significant threat to affected areas.

According to AEMET, the storm has already begun to enter from the southern flank, and its impact is expected to be most severe on Wednesday. The combination of saturated soils from previous storms and the intense rainfall from Charles increases the risk of flooding and landslides.

Current Weather Warnings Across Spain

AEMET has issued a series of weather warnings, with many regions on high alert. The map is dotted with yellow, orange, and red warnings, indicating varying levels of risk. The most critical areas are those where red warnings are in place, meaning extreme danger to life and property.

The warnings cover a range of hazards, including heavy rain, strong winds, and coastal phenomena. Residents and travelers are advised to stay informed and follow local authorities' instructions.

Canary Islands: First to Feel the Wrath

Before reaching the mainland, Storm Charles lashed the Canary Islands with wind gusts of 80 to 100 km/h in mountainous and exposed areas. There is a growing possibility that gusts could exceed 130 km/h in parts of La Palma and Tenerife, which could cause significant damage to infrastructure and vegetation.

The islands have experienced heavy rainfall as well, leading to localized flooding and hazardous driving conditions. Authorities have urged residents to secure loose objects and avoid unnecessary travel.

Mainland Spain: Extreme Rainfall and Landslide Risk

As Charles moves over the peninsula, AEMET warns of extremely high rainfall accumulations. The storm is expected to dump large amounts of rain from Wednesday to Thursday, with some areas potentially receiving over 300 mm over the course of both storms Bruna and Charles.

This is particularly concerning for regions in the Central System that were affected by wildfires last summer. The lack of vegetation cover means the soil is less able to absorb water, increasing the risk of landslides and mudslides. AEMET has issued a specific alert for these areas, warning that the terrain could become a trap of mud and debris.

Key Takeaways

• Storm Charles is driven by an atmospheric river, bringing extreme rainfall and strong winds.
• Red weather warnings are in place for parts of Spain, indicating extreme danger.
• The Canary Islands have already experienced hurricane-force gusts and heavy rain.
• Areas burned by wildfires are at high risk of landslides due to lack of vegetation.
• Accumulated rainfall could exceed 300 mm in some regions, leading to flooding.
• Residents are advised to stay indoors and follow official guidance.

Comparing Storm Charles to Previous Storms

Spain has faced several severe storms in recent years, but Charles stands out due to its atmospheric river and the heightened risk of landslides in fire-scarred areas.

What to Watch Next

The storm is expected to continue affecting Spain through Thursday, with conditions gradually improving on Friday. However, the risk of landslides may persist for several days after the rain stops, as the ground remains saturated.
