The Canary Islands Government has declared a rain pre-alert for La Palma from 8:30 a.m. this Thursday, 1 October, due to forecasts of heavy rainfall that could leave accumulated totals of up to 80 litres per square metre over 12 hours.
The measure affects the north and east of the island, where rainfall may be heavy, particularly in mid-altitude areas. The decision was taken by the Directorate-General for Emergencies, based on information from the State Meteorological Agency Aemet and other available sources.
Aemet has also issued a yellow warning for rain in eastern La Palma. The warning is in force from 10:00 a.m. on Thursday until 9:00 a.m. on Friday, 2 October. According to the forecast, rainfall could reach 80 millimetres over a 12-hour period, with the highest accumulations expected in the mid-altitude areas of the north and east of the island.
The Directorate-General for Emergencies has activated the pre-alert in accordance with the Canary Islands’ Specific Emergency Plan for Risks from Adverse Meteorological Phenomena, known as PEFMA.
Where the heaviest rain is expected
The area included in the pre-alert covers the north and east of La Palma. Emergency services warn of the possibility of moderate to heavy rainfall, with the most significant accumulations expected in the mid-altitude areas of these slopes.
These conditions require particular caution in areas prone to water accumulation, as well as in ravines and on roads that may be affected by heavy rain.
The rainfall episode is expected to develop between Thursday and Friday morning. Aemet’s warning specifically refers to the possibility of up to 80 millimetres of rain over 12 hours in eastern La Palma.
Residents and visitors are therefore advised to follow official updates and take precautions, especially in areas where heavy rainfall may cause localised flooding or difficult driving conditions.
Recommendations during heavy rain
The Directorate-General for Emergencies recommends avoiding unnecessary car journeys during periods of heavy rain. If driving is essential, drivers are advised to reduce speed, exercise caution and use main roads whenever possible.
The authorities also warn against driving through flooded areas or crossing bridges that have been submerged by water. People should avoid ravine beds, forest tracks and secondary roads when weather conditions are adverse, as these areas can become dangerous quickly during heavy rainfall.
At home, emergency services recommend checking drains, gutters and flat roofs to help prevent water accumulation. They also advise against entering flooded garages or basements, and recommend switching off the electricity if there is a risk of water entering the property.
The authorities remind the public that the emergency number 1-1-2 should be used only in urgent situations, while 012 is available for general enquiries. The Canary Islands Government will continue to monitor the situation in La Palma and may update the pre-alert depending on how the rainfall develops over the coming hours.
