Updated on Nov. 11, 2026 in Forecasts
Heavy and thundery rain is forecast through Spain and Portugal on Wednesday, November 11, 2026, with a risk of flooding. Heavy rain is expected to continue across Spain, Portugal, Italy and Austria on Thursday, November 12, 2026.
Why it matters
Forecast flooding risk across several countries in a single week means residents and travelers may need to plan for disruption to roads and travel. Early warnings give authorities and the public time to prepare.
The forecast describes heavy and thundery rain with flood risk but gives no rainfall amounts, so the scale of the threat is not yet quantified. Exact totals and the most affected localities remain unknown.
The details
Heavy and thundery rain is forecast across Spain and Portugal on Wednesday, with rain also in the Balearics, Corsica and Sardinia. On Thursday, heavy rain is expected in the north and west of Spain and Portugal, much of Italy, Austria and Switzerland, with rain and sleet in Finland and wintry showers in Norway.
Timeline

Thursday, November 12, 2026: heavy rain forecast across Spain, Portugal, Italy and Austria, with flooding expected in Austria and Switzerland.
Seasonal Patterns
Multi-country flood-risk forecasts like this one are a recurring feature of autumn weather across southern and central Europe, when Atlantic and Mediterranean systems often bring heavy rain to the region. The forecast fits that seasonal pattern rather than marking an unusual departure from it.
Drivers in Spain, Portugal and northern Italy should allow extra time and avoid flooded roads during the forecast rain on November 11 and 12. Residents should monitor official warnings from their national meteorological service for updates on any flood alerts in their area.
The takeaway
Check local weather alerts before travelling through the forecast rain zones this week, since flood risk can change quickly and roads may close with little notice. Plan extra travel time and avoid driving through standing water.
