AEMET, Spain's national weather agency, has warned that a new DANA storm system will bring intense, persistent rain to the Mediterranean coast and the Balearic Islands from Saturday, October 17, peaking into Sunday. Valencia, Catalonia, Murcia and the Balearics face the highest flood risk, less than three weeks after an earlier DANA killed one person and forced the rescue of about 90 residents in Albacete province.
Spain's State Meteorological Agency, AEMET, said on Wednesday, October 14, that a new DANA — an isolated depression at high altitude, sometimes called a "cold drop" — combined with cold air aloft will trigger a sharp weather change over the coming days. The agency's notice specifically flags the risk of an episode of intense precipitation over the Balearic Islands and the Mediterranean coastal and pre-coastal strip.
An abrupt end to an unusually warm spell
Before the change arrives, much of Spain is experiencing temperatures well above seasonal norms, with highs exceeding 25°C across much of the peninsula and near 30°C in the southwest and center. Cities such as Seville and Badajoz could still reach 33–34°C between Wednesday, October 14, and Friday, October 16, according to AEMET-based reporting, just before a frontal system begins to move in.
Timeline: rain spreads south and east from Saturday
AEMET's most likely scenario has the frontal system entering through the Cantabrian coast during the first half of Saturday, October 17, bringing continuous rain there and scattered showers and storms inland. During the second half of that day, precipitation is expected to intensify and spread toward the Mediterranean coast and the Balearic Islands.
The heaviest and most persistent rainfall is expected to concentrate on Sunday, October 18, along Mediterranean coastal and pre-coastal areas and in the Balearic Islands, where AEMET says significant rainfall totals could accumulate over the course of the episode.

How much rain, and how much uncertainty
AEMET itself has stressed that significant uncertainty remains over the exact track of the DANA, an associated upper-level trough, and surface wind flows, meaning it cannot yet say precisely which areas will receive the largest rainfall totals. The agency says the evolution of these three factors "will be decisive" in defining the scope of the episode.
Regional estimates reported for the Valencia area put likely coastal accumulations around 200 litres per square metre, with some preliminary model runs suggesting totals above 500 litres per square metre could occur in the metropolitan Valencia area over a longer, roughly nine-day window if the system lingers. These figures are explicitly described as preliminary and are updated twice daily, not a fixed AEMET forecast.
It's still too early to pinpoint the intensity.

Temperatures expected to fall sharply
Alongside the rain, AEMET expects a generalized drop in both daytime and nighttime temperatures, most pronounced in the northwestern quarter of the country and the Cantabrian mountains, with milder change in the Balearics. In the Valencia area specifically, forecasts cited by regional media point to highs falling from 24–27°C on Saturday to around 20°C on Sunday — a 7 to 10°C drop — with inland overnight lows dipping below 10°C.

Second DANA episode in under three weeks
This is being described by Spanish meteorological reporting as a new, distinct DANA, arriving less than three weeks after an earlier one struck southeastern Spain. On the night of October 2, heavy rain linked to that earlier DANA caused flash flooding in Madrigueras, a town in Albacete province. At least one person died, and firefighters rescued around 90 residents, according to World Central Kitchen, the aid organization that deployed food trucks and a local restaurant partner to support affected families.
Questions
What is a DANA?
A DANA — depresión aislada en niveles altos, or isolated depression at high altitude, sometimes translated as a "cold drop" — is an upper-level low-pressure system that, combined with cold air aloft, can destabilize the atmosphere and trigger intense, sometimes slow-moving rainfall, according to AEMET-based reporting.
When will the rain reach Spain?
AEMET's most likely scenario has a frontal system entering via the Cantabrian coast on the morning of Saturday, October 17, then intensifying and spreading toward the Mediterranean coast and Balearic Islands that afternoon, with the heaviest, most persistent rain expected on Sunday, October 18.
Which regions face the highest flood risk?
AEMET and regional reporting point to the Comunitat Valenciana (especially south Valencia province and Alicante), the Balearic Islands, Catalonia and Murcia as the areas most likely to see the heaviest rain.
How much rain is actually expected?
AEMET says there is still considerable uncertainty about exact totals because the DANA's track is not fixed. Preliminary regional estimates for the Valencia coast suggest around 200 litres per square metre, with some longer-range model projections for metropolitan Valencia running higher over a multi-day window, though these figures are explicitly preliminary.
Is this the same storm that caused deadly flooding earlier in October?
No. Spanish meteorological reporting describes this as a new, separate DANA. An earlier DANA caused flash flooding in Madrigueras, Albacete province, on the night of October 2, killing at least one person and prompting the rescue of about 90 residents.
How the world is telling it
SpanishSpanish outlets frame the story around AEMET's own acknowledged forecast uncertainty and a sharp "desplome térmico" (temperature collapse) after an unusually warm October, with particular attention on the Comunitat Valenciana given its exposure to Mediterranean DANA episodes; coverage repeatedly stresses that exact rainfall totals cannot yet be pinned down.

Hurricanes, typhoons and cyclones are the same storm type, named differently by ocean basin, and they form when warm ocean water, rising air and low wind shear combine over tropical waters. This guide explains the formation process step by step and lists the preparedness actions recommended by the US National Weather Service and NOAA, using Typhoon Champi's October 2026 strike on Taiwan as a current example.
Odisha has ordered schools and colleges closed in five southern districts and put more than 300 disaster-response teams on standby ahead of Cyclone Arnab, a Bay of Bengal system forecast to cross the north Andhra Pradesh–south Odisha coast around October 28, 2026. Authorities are preparing shelters, evacuation transport and hospital transfers for pregnant women in low-lying coastal areas.
Typhoon Champi, designated Typhoon No. 30 of the 2026 season, is forecast to approach Japan's Kyushu region around Monday, October 26, after weakening from super-typhoon strength. The Japan Meteorological Agency is warning of heavy rain, flooding and landslides across western and central Japan as the storm interacts with a stalled weather front.
Forecasts are built by feeding billions of daily observations into supercomputer models that solve the physics equations of the atmosphere, then running the model dozens of times with slightly different starting conditions to gauge uncertainty. According to the US National Weather Service, a 5-day forecast is right about 90% of the time, a 7-day forecast about 80%, and forecasts beyond 10 days are close to a coin toss.
