What changes for holidaymakers in the south?

The pre-alert applies to the whole of Tenerife, not just the north. On Tenerife and La Gomera, rainfall is expected mainly from Sunday morning, 1 November.

The official notice names no specific restrictions for southern resorts such as Playa de las Américas or Costa Adeje. Nor does it announce any general closure of roads, airports, schools or visitor attractions.

When does it become critical on Tenerife?

From late Saturday afternoon, bands of rain may move onto the islands from the west. For La Palma and El Hierro, the government initially cites a higher probability of locally heavy showers.

The weather system may then shift eastwards and reach Tenerife mainly from Sunday morning, 1 November 2026. Exactly where the low tracks is, according to the government, highly uncertain.

What does the government actually advise?

The government advises following updates through the media and checking roofs and drains. Problems at overflowing barrancos should be reported to the relevant Ayuntamiento.

During heavy rain, you should avoid low-lying areas, barrancos and roads at risk of flooding. According to the reports available, no additional rules, fees or special applications apply to foreign residents and tourists.

In an emergency, call 112. Information is available on 012.

How reliable is the forecast?

The government considers the position and track of the low-pressure system, as well as the distribution and intensity of the rain, to be highly uncertain. The forecast may therefore change, and the warning may extend to further islands.

The AEMET hourly forecast for Santa Cruz de Tenerife initially showed a 20 percent chance of rain in the respective time windows on Saturday morning. No specific hazard warning had appeared there by 11:00.

What about roads, airports and excursions?

The official notice does not announce any general closure of roads, airports, schools or visitor attractions. Traffic disruption, closures or evacuations on Tenerife are not yet confirmed in the sources checked.

Anyone who still has to drive should use main roads, drive slowly and watch water levels. The government advises against driving through flooded areas and parking there.

What happens next?

The Dirección General de Emergencias says it will monitor the situation continuously and adjust the pre-alert if the weather changes. The next official AEMET forecasts and notices from the government and affected municipalities are now key.

New information is expected on Saturday 31 October and Sunday 1 November 2026. The published government notice gives no end time for the pre-alert.
