The Emergency Management Agency has updated its weather alert for the Canary Islands, placing El Hierro, La Palma, La Gomera, Tenerife, and Gran Canaria under prealert status from 11.30 am today. A similar prealert is in effect for coastal phenomena, particularly around Tenerife and on the northern and western shores of the other islands.
Regarding the rain alert, the agency refers to the State Meteorological Agency (Aemet), which reports that the weather front associated with Storm Bruna has affected the Canary Islands in a less severe and more disorganised manner than initially expected, leading to a decrease in predicted rainfall.
However, La Palma, La Gomera, El Hierro, and Tenerife could see rainfall exceeding 20 litres per square metre in one hour and up to 60 litres in 12 hours, particularly affecting the western and southern slopes, with La Palma experiencing higher probabilities in its midlands. This rain is expected to continue until 6 pm on Sunday.
In Gran Canaria, rainfall may also exceed 20 litres per square metre in an hour, reaching 25 litres in the peaks, and up to 40 litres in 12 hours, especially in the western, southern, and northwestern areas of the island.
Lanzarote, Fuerteventura, and La Graciosa are likely to experience locally intense rainfall, which could similarly exceed 20 litres per square metre in one hour. On Gran Canaria, Lanzarote, Fuerteventura, and La Graciosa, these rainfall conditions may last until midnight on 9 November.
As for coastal phenomena, the Emergency Management Agency notes that although wind intensity is expected to gradually decrease this afternoon and evening, adverse wave conditions will persist. Forecasts indicate a swell from the north and northwest, with waves of 3 to 4 metres affecting the northern and western shores of the islands.
Furthermore, wind associated with a southwest direction is expected, particularly around the metropolitan area and southern coast of Tenerife, as well as the northwest coast of Gran Canaria near the Anaga-Agaete channel, where gusts could reach force 7 (50 to 61 kilometres per hour).
Residents are advised to take extra precautions in exposed coastal areas, especially during high tides, and to avoid access to docks, piers, and breaking wave zones.
