What does the yellow warning level mean?
The yellow warning level from AEMET (Agencia Estatal de Meteorología, the state weather service) corresponds to a situation with a low level of danger from adverse weather phenomena. It warns of possible disruption to certain activities, but is not a general ban on being outdoors or travelling.
The warning runs on 6 October 2026. Localised falls of up to 20 litres of rain per square metre are possible in one hour.
The heaviest rainfall is expected in mid-level and higher ground in the north, northeast and south of El Hierro. Thunderstorms are also possible at times.
What additional measure is in force across the Canary Islands?
The Dirección General de Emergencias del Gobierno de Canarias declared a pre-alert for rain from 12:00 on 6 October 2026. It applies to El Hierro, La Palma, La Gomera, Tenerife and Gran Canaria.
The decision is based on information from AEMET and other sources. It is made under the Plan Específico de Emergencias de Canarias por Riesgos de Fenómenos Meteorológicos Adversos (PEFMA), the Canary Islands emergency plan for adverse weather phenomena.
The 112 Canarias emergency service is sharing the situation and self-protection advice. The pre-alert level is the lowest level of the Canary Islands emergency system.
What does AEMET expect on El Hierro?
AEMET expects changeable cloud on El Hierro, with skies becoming increasingly overcast in the afternoon. There will also be light scattered showers and some calima in higher layers of the atmosphere.
Temperatures will remain largely unchanged. Northeast wind will blow along the coasts. The forecast mentions high tropical humidity and convective developments favoured by the terrain.
There is no separate warning for the coastal waters. AEMET expects north or northeast wind of force 3 or 4, with intervals of force 5 on the open sea off the north and northwest coast, together with moderate or rough seas and a northerly swell of around one metre.
What should residents and visitors bear in mind?
The authorities recommend avoiding car journeys during heavy showers and not entering areas at risk of flooding. Flooded bridges should never be crossed.
Walkers, campers and outdoor visitors should review their plans, especially in higher ground and near barrancos and other drainage channels. The authorities advise against camping in barrancos or other places at risk of flooding.
It is also recommended to check roofs and drains, follow instructions through official communication channels and watch out for possible rockfall, which can precede larger landslides.
What restrictions have been ordered?
The information available does not mention any ordered closures, cancelled ferry or flight connections, price changes, application deadlines or financial aid for El Hierro. Likewise, no specific evacuation or local closure is reported.
Changes depend on the actual development of rainfall and later instructions from the authorities. The next key moment was the start of the AEMET warning and the Canary Islands pre-alert at 12:00 on 6 October 2026.
After that, it will be decided whether the warning is extended or lifted.
What happens after 6 October?
The warning is initially limited to 6 October 2026. Whether it is extended depends on the further development of rainfall.
The authorities recommend following official communication channels. These include AEMET, the Dirección General de Emergencias del Gobierno de Canarias and the 112 Canarias emergency service.
No specific forecasts for El Hierro for the period after the warning window are available in the published information.
