Warm air mass bringing haze and temperatures of 30°C activates alert for forest fires

The Canary Islands are under a pre-alert for the risk of forest fires due to a warm air mass bringing haze and 30 degree temperatures to Tenerife and Gran Canaria.

The alert has been activated today, Wednesday, by the Directorate General of Emergencies, based on meteorological data from the State Meteorological Agency (AEMET) and other sources.

The measure follows the guidelines of the Canary Islands' Special Civil Protection Plan for Forest Fire Emergencies (INFOCA).

Weather Conditions and Risk Factors

The region is experiencing a surge of warm, dry air accompanied by calima, resulting in unseasonably high temperatures nearing 30°C. Key contributing factors include:

• Low humidity: Relative humidity levels are expected to drop below 30% at altitudes above 600 metres, reaching as low as 400 metres in southern slopes.
• Temperature inversions: These limit moisture circulation.
• Strong winds: Southern winds with strong gusts, particularly in leeward and northern areas, are anticipated to intensify fire risk.

The prolonged drought in the main islands exacerbates the wildfire threat, although recent rainfall in the western islands has helped to alleviate water shortages and improved vegetation health.

Coastal Weather Alerts

In addition to wildfire concerns, the Canary Islands remain under pre-alert for coastal phenomena. The northwestern seas are expected to see rough conditions with waves between 1.5 and 3.5 metres, particularly along the northern and western coasts of El Hierro, La Palma, La Gomera, Fuerteventura, and Lanzarote, as well as the northern coasts of Tenerife and Gran Canaria.

Safety Recommendations

The Government of the Canary Islands urges residents and visitors to take precautions to minimize wildfire risks:

• Avoid outdoor fires: Do not discard lit cigarettes or matches.
• Leave no waste: Dispose of trash properly, especially in forested areas.
• Report smoke immediately: Call emergency services at 112 with precise location details if smoke or fire is observed.
• Refrain from unauthorized camping: Stick to designated areas and avoid isolated zones.
• Protect your property: Clear dry vegetation and debris around homes and vacant lots to reduce fire hazards.

For coastal safety, residents should avoid risky activities near affected shores and remain informed about maritime conditions.

Regional Restrictions and Monitoring

The public is advised to adhere to access restrictions and activity limitations imposed by local councils and municipalities. Measures include restricted access to forest areas and the suspension of certain activities in high-risk zones until the alert is lifted.

The Directorate General of Emergencies has assured continued monitoring of the situation and will issue updates as necessary.
