Spain’s weather agency Aemet is reporting very wet and locally stormy conditions in the Canary Islands on 2 November 2026. Particularly on La Palma, El Hierro and La Gomera heavy to very heavy showers with thunderstorms are possible, with short, intense bursts of rainfall in some areas. The Government of the Canary Islands had already updated warning levels for these three western islands on 1 November and warned of possible hourly rainfall totals of more than 30 millimetres.
At the same time, Aemet expects atmospheric instability to increase across large parts of Spain at the start of the week. This is due to an influx of colder air at higher altitudes. For 3 November, the agency considers the formation of a so-called DANA — a cut-off upper-level low — over the north of the Iberian Peninsula possible. Combined with moist Mediterranean air, very heavy and sometimes prolonged showers could then occur on the coast of Catalonia and on the Balearic Islands In the Cantabrian region, Aemet expects widespread lighter rainfall.
The warnings relate to a dynamic situation whose precise effects may vary greatly from region to region. Aemet and the regional civil protection authorities therefore point to rapidly rising water levels in barrancos, possible flooding in urban low-lying areas and short-notice disruption to transport. Power supply disruptions cannot be ruled out on exposed islands. Aemet is continually publishing specific warning levels in its official notices.
Forecast assessments: statements about expected areas of rainfall, the position of a possible upper-level low and the intensity of showers in midweek are model-based projections, not confirmed events. Whether a DANA develops and where the main areas of activity form will depend on conditions over the next 24 to 48 hours. Atlantic low-pressure systems could have an additional influence later in the week, but the extent and timing remain uncertain.
The latest updates were published on 2 November and cover the immediate period up to midweek. Travellers and local infrastructure operators should make decisions based on the latest official forecasts and warnings, as localised thunderstorms can escalate at short notice.
