Weather in the Canary Islands: pre-alert for rainfall

The cold front, which will divide into two as it approaches the Canary Islands, is expected to reach La Palma in the morning and will advance to El Hierro by midday.

Today, the western islands of the Canary Archipelago are experiencing increased instability due to the arrival of a high-altitude trough of cold air, leading to significant cloud formation. A cold front, splitting into two upon nearing the Archipelago, is set to reach La Palma in the morning and then advance to El Hierro around midday. This front is expected to bring rainfall that could be moderate and, though less likely, may become locally intense, with the possibility of storms in the vicinity of both islands.

Consequently, the Directorate General of Emergencies of the Canary Islands Government has declared a pre-alert for rain on La Palma and El Hierro, starting from 11:00 hours. This is in response to forecasts predicting rainfall that could amount to 15 litres per square metre within an hour, based on warnings issued by Aemet and other sources.

In La Gomera and Tenerife, the day will see an increase in cloudy intervals, progressing to overcast skies with a chance of moderate rainfall, mainly affecting the northern and western slopes. Light rainfall in other areas cannot be ruled out.

Meanwhile, in Gran Canaria, Fuerteventura, and Lanzarote, skies are expected to be generally lightly cloudy with a low probability of isolated, weak rain in the afternoon. A yellow warning for coastal phenomena is in effect from tonight until midday Friday in the east, south, and west of Tenerife.


AEMET initiates pre-alert status for rainfall in the Canary Islands

Yesterday, scattered showers were observed in various parts of Tenerife, La Palma, El Hierro, La Gomera, and Gran Canaria. However, the rainfall was not as heavy as anticipated, often being weak and localised over short periods.

The heaviest rainfall occurred in the Candelaria and Güímar areas, with 20 litres per square metre recorded. There was also a sea spout formation observed off Radazul and Tabaiba in the afternoon.

Significant rainfall was also recorded in the metropolitan area, with over 12 litres in La Cuesta and Tenerife North Airport. In the north, San Juan de la Rambla reported 8 litres/m2.

In La Palma, Fuencaliente recorded 3 litres/m2, San Andrés y Sauce and El Paso 1.5 litres/m2, and Puntagorda and Tijarafe 1 litre/m2.

Temperatures have slightly dropped, with highs of 26.5ºC in Vallehermoso (La Gomera) and 25ºC in La Aldea, Gran Canaria. Some areas even experienced temperatures 10 degrees lower than the previous day.

Authorities have lifted the wind alert in La Palma and Tenerife, and the pre-alert status has also ended in the other islands. Last Tuesday’s strong wind gusts led to nearly thirty flight cancellations at Mazo airport, damage to fruit trees and crops, particularly on the Isla Bonita, and the collapse of a disused wind turbine in Lanzarote.

The highest wind gust recorded yesterday was 85 km/h in Izaña, followed by 60 km/h in Vega de San Mateo (Gran Canaria), 56 km/h in Alto de Igualero (La Gomera), and 51 km/h in Breña Baja.
