Canary Islands on pre‑alert due to dust haze

In response to the situation, the Canary Islands Health Department urges the public to adopt preventive measures.

Government Response

The Government of the Canary Islands, through the Directorate General of Emergencies, has placed the entire archipelago on a pre‑alert for calima (dust storm) this weekend. The episode officially began on Saturday, primarily affecting mid‑altitude and high‑altitude areas, and could last at least until next Monday.

The decision is based on data from the State Meteorological Agency and other sources, applied under the Specific Emergency Plan for Adverse Meteorological Phenomena (PEFMA).

• On Friday, no significant dust influx from the African continent was recorded, but air quality was already sub‑optimal.
• A new influx of suspended dust is expected this weekend.
• The episode will start on Saturday, continue on Sunday with a higher dust load, and extend at least through Monday.

“The phenomenon will reduce visibility and may exacerbate health problems for people with chronic and respiratory diseases.”

In parallel, the islands are also on pre‑alert for coastal phenomena. Since 19:00 h on Friday, forecasts indicate:

• Northeastern winds of force 4–5, increasing to force 6 in the channels between islands.
• Combined north and northwest seas, especially from swell, with waves reaching 3 m and up to 4 m north of La Palma, where wind impact may be stronger.

Health Precautions

The Canary Islands Health Department, anticipating dust presence on several islands in the coming days, recommends the following preventive actions:

• Avoid prolonged outdoor exposure.
• Keep doors and windows closed.
• Refrain from strenuous physical activity outdoors.

Given that the alert coincides with Carnival celebrations and large public gatherings, special advice is directed to:

• Individuals in sensitive groups.
• People who typically experience mild symptoms during dust events (e.g., eye, nose, or throat irritation).

Additional recommendations:

• Reduce time spent outside as much as possible.
• Adapt participation in outdoor activities where feasible.
• Prioritize indoor venues for celebrations.

High concentrations of suspended dust can cause mild symptoms such as nasal or throat irritation, eye itching, or cough, and may trigger or worsen:

• Asthma attacks.
• Chronic obstructive pulmonary disease (COPD) or emphysema.
• Cardiovascular conditions.
