The isolated depression at high levels (DANA) that will hit Spain this weekend will leave up to 50 liters of rain per square meter in one hour in Mediterranean areas and hailstorms. Its effects will begin to show already today in the northeast of the peninsula. This autumn appetizer is the time that will accompany the last summer return operation that began this Thursday: 6,820,000 long-distance movements on the highway are expected until Sunday.

An autumnal atmosphere will predominate throughout the weekend, with temperatures below what is usual for these dates in a good part of the peninsula, according to the predictions of the State Meteorological Agency.

The General Directorate of Traffic indicates that departure movements are also expected during the weekend due to the beginning of the September holidays, especially towards coastal tourist areas. As always, the DGT recommends planning trips in advance and, if possible, avoiding the most unfavorable hours: these are these.

The communities of Aragón and Navarra will activate the orange alert (significant risk) this Friday afternoon, due to rains of 30 liters per square meter in one hour; from there they will spread with greater intensity through the eastern end of the country from Saturday, according to Aemet.

As of today, weather warnings are also expected, although yellow with a slightly lower risk, for rains of up to 15 liters per square meter in one hour, in Castilla-La Mancha, in the Cuenca mountains and in Guadalajara late on Friday, and also in Madrid, in the mountains, and also by strong storms.

On Saturday, the alerts will extend to the eastern end until they affect more than a dozen regions, of which the Balearic Islands, Catalonia and the Valencian Community will be at an orange level, due to rains of up to 50 liters per square meter on islands such as Ibiza or Formentera. In Tarragona (Catalonia) and the interior of Castellón (Valencian Community) up to 40 liters per square meter can be collected in one hour; In addition, storms accompanied by hail and very strong gusts of wind are expected.

In the eastern Cantabrian area, the Ebro valley and this peninsular, rainfall could be more intense and persistent, with the largest accumulations.

During Sunday, it is likely that the Dana will center in the southwest of the peninsula and establish a humid and intense Levante flow, providing moisture from the sea and favoring abundant rainfall. Again the showers and storms will affect a large part of the peninsula and the Balearic Islands, according to Aemet.

The greatest probability and intensity of the precipitations will possibly be in the east, southeast quadrant and center of the peninsula, where they will be strong or very strong and persistent. Very strong gusts of wind are also expected in these areas.
