What does the yellow warning mean for El Hierro?
The Agencia Estatal de Meteorología (AEMET, Spain's national weather service) classifies yellow as a low level of danger. For El Hierro, mostly cloudy skies, little change in temperatures and initially light easterly winds are expected, with winds possibly becoming moderate during the morning.
According to AEMET, the showers may be heavy and persistent and may be accompanied by thunderstorms. The probability of precipitation is between 40 and 70 percent. Up to 15 litres per square metre are expected within one hour and 60 litres per square metre within twelve hours.
According to the report by eldiario.es, El Hierro is the most affected island in the Canaries this Tuesday. On the other islands, light or locally moderate rainfall is expected in the mountain areas.
Which pre-alert level has been in force since Monday?
Diario de Avisos reports the AEMET risk period starting at 12:00 on Monday 19. This so-called prealerta is based on AEMET forecasts and the Canary Islands emergency plan PEFMA.
PEFMA is the Plan Específico de Protección Civil y Atención de Emergencias por Riesgos de Fenómenos Meteorológicos Adversos, the special plan for civil protection and emergency response to adverse weather events. The pre-alert level means that the authorities are monitoring the situation and urging the public to be cautious.
What should residents and visitors do on Tuesday?
The published advice is to take precautions and avoid unnecessary journeys, especially during heavy showers. If there is a risk of flooding, low-lying areas, barrancos and flooded roads should be avoided.
Barrancos are the typical Canarian ravines and dry valleys that can quickly turn into fast-flowing watercourses during heavy rain. The authorities recommend not crossing such places either on foot or by vehicle.
Walks should be postponed on Tuesday. The available official information does not mention any new fees, entry requirements, application deadlines or general closures.
What are conditions like around the coast of El Hierro?
The AEMET coastal weather forecast expects no warning-level conditions in the Canary Islands coastal areas from Tuesday at 20:00 until Wednesday 21 October at 20:00.
What impact is possible on El Hierro?
The available sources do not mention any specific closures of roads, ports, airports, schools or tourist facilities on El Hierro. There are also no confirmed damage reports or figures on actual rainfall amounts after the event.
Experience shows, however, that heavy rain on El Hierro can lead to landslides, suddenly swelling barrancos, local flooding and road closures. The Gobierno de Canarias has described similar effects for the western islands.
In the event of immediate danger, the Gobierno de Canarias recommends calling the emergency number 112. Up-to-date information should be followed through the official channels of AEMET and the Gobierno de Canarias.
What happens after Tuesday?
The AEMET coastal weather forecast expects no warning-level conditions in the Canary Islands coastal areas from Tuesday at 20:00 until Wednesday 21 October 2026 at 20:00. For land areas, the available sources contain no information on warnings for Wednesday.
Whether the yellow warning for El Hierro will be extended or lifted had not been published in the sources assessed by Tuesday. Travellers and residents should check the AEMET warning overview and the announcements from the Gobierno de Canarias during the day.
