Government declares weather alert in the Canary Islands due to rain, flooding and strong winds

The Government of the Canary Islands has officially activated a state of alert for heavy rain and flooding, based on the latest forecast issued by the State Meteorological Agency (AEMET). The declaration, issued by the Directorate-General for Emergencies, is made under the Specific Emergency Plan for Adverse Weather Conditions (PEFMA), as established by Decree 18/2014.

The alert will take effect from 3:00 p.m. on Wednesday, 12 November, while a separate alert for strong winds will begin at 12:00 noon on the same day. Both alerts apply to the entire archipelago.

Storm Claudia approaches the islands

AEMET reports that a cold front associated with Storm Claudia, currently located southwest of the British Isles, is advancing towards the Canary Islands. The system is expected to cross the islands from west to east:

• It will reach La Palma around midday on Wednesday.
• During the night, the rain will intensify as the system moves over Tenerife, La Gomera and El Hierro.
• By Thursday afternoon, it will be affecting Fuerteventura and Lanzarote, where locally intense showers are also possible.

Meteorologists warn of persistent rain, sometimes heavy or very heavy. On the mountainous islands, especially along western and southern slopes, rainfall could exceed 20–30 mm in one hour, and up to 80–100 mm in 12 hours. Lanzarote and Fuerteventura may also experience sudden downpours, with accumulations exceeding 15 mm in one hour.

According to AEMET, Storm Claudia will remain nearly stationary over the Atlantic northwest of the Iberian Peninsula, continuously sending active fronts towards the archipelago. In addition to rain, the storm will bring strong south-westerly winds and rough seas.

Risk of localised flooding and storm damage

The heaviest showers are expected on the most exposed slopes, where there is a risk of sudden flooding in ravines and runoff areas. Strong wind gusts may cause branches, trees or loose construction materials to fall. Rough seas and storm surge conditions may affect promenades, ports and seafront areas.

Authorities urge residents to take preventive measures and avoid unnecessary risks.

Official safety recommendations

The Directorate-General for Emergencies has issued clear guidance to residents and visitors of the islands:

• Do not attempt to cross flooded areas, ravines or riverbeds, even if they appear dry.
• Avoid using lifts during periods of heavy rain or potential flooding.
• Call 112 only in situations of real emergency.
  For general information, use 012.
• Stay away from scaffolding, cranes, billboards, deteriorated façades or any object that could be dislodged by the wind.
• Secure or remove flowerpots, outdoor furniture, and any loose objects from balconies and rooftops.

In the case of thunderstorms, people are advised not to approach areas struck by lightning and to avoid running in open spaces.
