Executive Summary for Heavy Rainfall and Thunderstorms Across Spain
Spain is preparing for a period of unsettled weather through Sunday (18 October), following several days of unusually warm and stable conditions. According to Spain’s State Meteorological Agency (AEMET), showers and thunderstorms may develop across parts of the country, with the possibility of locally heavy rainfall. The national Civil Protection authority has highlighted the Mediterranean coastline and Balearic Islands as areas of particular concern from Saturday (17 October) while thunderstorms are also possible inland. Forecast uncertainty remains regarding the precise locations likely to receive the heaviest rainfall. The principal operational risks include localized flooding, reduced road visibility, transport delays and disruption to outdoor activities. Businesses in exposed areas may face challenges involving employee travel, deliveries, construction schedules and access to facilities. Andalucía has also been forecast to experience showers and thunderstorms, with locally heavy rainfall possible in parts of Almería province. Businesses should monitor regional warnings rather than assume that conditions will be uniform across Spain.

What is Risk Analysis in the Context of Environment Events
Environment risk analysis for severe or unsettled weather evaluates the likelihood that rainfall, thunderstorms, strong winds and localized flooding will affect infrastructure, transport networks, employees and commercial operations.
Known Hotspots and Sensitive Areas
High Impact
- Mediterranean coastline and Balearic Islands: Spain’s Civil Protection authority has identified these areas as potential locations for significant rainfall from Saturday (17 October). Persistent or intense showers could increase localized flood risk and disrupt coastal transport and commercial activity. The exact locations of the heaviest rainfall remain uncertain.
- Eastern Spain: The forecast indicates that the eastern half of the country may experience the heaviest and most likely rainfall and thunderstorms. Businesses should monitor local warnings and prepare for potential travel and delivery delays.
Medium Impact
- Andalucía, including Almería province: Showers and thunderstorms are forecast, with locally heavy rain possible in Almería. Rainfall may affect road travel, outdoor work and access to commercial facilities. Strong easterly winds have also been forecast along parts of the Mediterranean coast and the coast of Cádiz.
- Interior regions: Thunderstorms may develop in parts of the interior, potentially producing localized travel disruption and interruptions to outdoor operations. The precise locations and severity will depend on how the weather system develops.
Low Impact
- Areas outside the main forecast rainfall zones: Locations that receive only light or intermittent showers may experience limited direct disruption. However, local conditions can change rapidly, and businesses should continue monitoring official forecasts.
Impact on Transportation and Services
- Road transportation: Heavy rain may reduce visibility, increase stopping distances and cause localized flooding, potentially delaying passenger travel and freight deliveries.
- Rail transportation: Severe weather may affect exposed infrastructure or services.
- Air transportation: Thunderstorms may affect airport operations and flight schedules locally.
- Maritime transportation: Strong winds and unsettled coastal weather may complicate some marine operations. Operators should check current local marine forecasts before departure.
- Utilities and telecommunications: Lightning and localized flooding could affect exposed infrastructure.
- Business operations: Outdoor construction, agriculture, tourism and logistics operations may require schedule adjustments if heavy rain or thunderstorms develop.
Recommended Actions
- Monitor official warnings: Check AEMET and Civil Protection updates for the latest regional forecasts, rainfall warnings and changes in expected storm intensity.
- Review flood exposure: Inspect drainage systems and identify vulnerable entrances, basements, storage areas and equipment.
- Adjust travel plans: Allow additional journey time and avoid flooded roads or underpasses. Do not attempt to drive through floodwater.
- Protect outdoor workers: Suspend exposed activities during lightning or hazardous weather and ensure employees can access safe shelter.
- Prepare logistics contingencies: Review delivery windows, alternative routes and communication arrangements for suppliers and customers.
- Secure exposed assets: Move vulnerable equipment and stock away from areas prone to water ingress, and secure loose materials where strong winds are forecast.
- Reassess plans daily: Because the precise areas of heaviest rainfall remain uncertain, update operational decisions as forecasts become more specific.

Final Thoughts
The forecast points to a period of elevated weather-related risk across parts of Spain through 18 October. The Mediterranean coastline, Balearic Islands and eastern regions warrant particular attention, while parts of Andalucía may also experience heavy showers and thunderstorms. Businesses should focus on flood preparedness, employee safety and flexible transport arrangements. The geographic uncertainty means local warnings should guide decisions, rather than treating the entire country as equally affected.
