What does the yellow warning level actually mean?
The yellow warning level is the lowest of three risk levels in the AEMET (state meteorological agency) system. It means a low risk, but individual areas or exposed assets may already be affected.
For Lanzarote, including La Graciosa, AEMET expects heavy showers that may be accompanied by isolated thunderstorms. Up to 15 millimetres of precipitation is possible within one hour.
The heaviest showers are expected on Friday afternoon and overnight into Saturday. According to La Voz de Lanzarote, the rain is likely to be heaviest in the north-east of the island, particularly in the final hours of the afternoon.
Why is the weather unstable right now?
The cause is a DANA (Depresión Aislada en Niveles Altos), an isolated high-altitude depression. According to La Voz de Lanzarote, it forms from a tongue of cold air that breaks away from the polar latitudes.
According to the report, the forecasts show “considerable uncertainty” about the exact position of this DANA. Current estimates suggest it will not hit the archipelago directly, but will remain north of the islands, between the Canaries and the Gulf of Cádiz.
What is confirmed is the rain warning for Lanzarote, but not a certain direct hit from the DANA. Its development and track remain changeable.
What advice applies to residents and visitors?
The Consorcio de Seguridad y Emergencias de Lanzarote y La Graciosa recommends reconsidering outdoor activities during the critical period and checking the weather development regularly.
Low-lying areas, barrancos (dry valleys), drainage channels and roads at risk of flooding should be avoided. Vehicles should not be parked in barrancos or other flood-prone areas.
Flooded roads should never be crossed by car. During thunderstorms, keep your distance from metal structures and isolated trees. The same advice applies to expats and holidaymakers as to local residents.
Are there any closures or other restrictions?
The available sources do not mention any specific closures of airports, ports, tourist attractions, schools or roads. No new charges, legal deadlines or changed entry requirements are known either.
The warning level mainly means an increased risk of short-term flooding and difficult road conditions. There are so far no official reports of property damage, evacuations or the activation of a higher emergency level.
A weather warning alone is not a declaration of emergency. It does not automatically trigger closures, evacuations or compensation.
How will the weather develop on Saturday?
Reports differ on when the yellow warning ends: one says Saturday 10 October 2026 at 06:00, provided there are no changes; another says Saturday at 00:00. La Voz de Lanzarote says only that it will last “at least into the early hours of Saturday morning”. The weather instability may nevertheless continue after that.
According to the reports, further showers are possible on Saturday, even if the formal warning has expired. AEMET may update the warning up to 9 October if the amount of precipitation, thunderstorm risk or duration changes.
Temperatures between 21 and 27 degrees are expected on Friday. The wind will be light to moderate from the north.
