Canary Islands declare pre-alert for heat and calima
The Directorate-General for Emergencies of the Canary Islands Government has declared a pre-alert for high temperatures across all the islands from 11:00 this Monday, 14 September. The measure coincides with the activation of a pre-alert for widespread calima from 00:00, ahead of an episode that will combine intense heat and airborne dust until at least Tuesday.
According to the regional government, high temperatures are expected on Monday and Tuesday, with varying intensity depending on the island. The forecast will be kept under review in case the weather warnings are updated.
Fuerteventura and Lanzarote to bear the brunt
Fuerteventura will record the highest temperatures, with maximums of up to 37°C and even higher values possible. In Lanzarote, 36°C could be reached. The heat will initially affect inland areas of both islands on Monday and will tend to spread to the southern and south-eastern coastlines over the course of Tuesday.
Gran Canaria could see 37°C
In Gran Canaria, temperatures could reach 34°C from Monday across large parts of the south and west, with isolated peaks of 35°C. On Tuesday, up to 37°C could be recorded locally in areas of the southern half of the island, with the possibility of those values spreading to the south-eastern coastline. In addition, various mid-altitude areas in the north of Gran Canaria could reach 34°C to 35°C during Tuesday.
Tenerife, La Gomera and La Palma
In Tenerife, temperatures of between 32°C and 33°C are expected in the mid-altitude and high ground of the south and west, as well as in parts of the metropolitan area, on Monday. On Tuesday, 35°C could be reached locally in the southern mid-altitudes and up to 36°C on the southern slopes of the metropolitan area.
La Gomera could record between 34°C and 35°C on Tuesday in the high ground and mid-altitudes of the south, with those values potentially even reaching the western coastline. In La Palma, maximums will hover around 30°C on Monday in the mid-altitudes of Tijarafe, the Caldera de Taburiente and El Paso. On Tuesday they could rise to 32°C in those areas and in the north-western mid-altitudes, while across the island’s mid-altitudes and high ground up to 31°C is expected.
El Hierro
In El Hierro, temperatures could reach between 31°C and 32°C on Tuesday across much of the island, except along the coasts, where they will be somewhat more moderate. In El Pinar and the north-eastern high ground, the thermometer could reach between 33°C and 34°C.
Saharan dust brings poor air quality
This episode of high temperatures will be accompanied by a widespread calima sweeping into the Canary Islands from the early hours of Monday. The Saharan dust in suspension will leave air quality unfavourable or very unfavourable in various parts of the archipelago.
The highest concentrations are forecast in the low-lying areas of Lanzarote and Fuerteventura, where levels will exceed 100 micrograms per cubic metre from Monday morning. In the mid-altitudes and high ground of the remaining islands, particle concentrations may exceed 75 micrograms per cubic metre and occasionally reach 100, with particular impact expected in the middle and higher areas of Gran Canaria and La Palma.
Health warnings and official advice
The activation of both pre-alerts follows the forecasts of the State Meteorological Agency (Aemet) and is being applied under the Canary Islands Specific Emergency Plan for Adverse Meteorological Phenomena Risks (Pefma).
The Canary Islands Government reminds the public that the combination of heat and calima can cause or aggravate health problems, particularly in people with chronic, respiratory or cardiovascular conditions, as well as children, older people and other vulnerable groups. The Directorate-General for Emergencies urges the public to consult official warnings and follow self-protection recommendations during this episode.
