The DANA that hits from Tuesday to various areas of the Mediterranean focuses this Thursday on its heaviest rainfall in western Andalusiaalthough It will also rain heavily on the Mediterranean coast and the Central System. The State Meteorological Agency (AEMET) has activated orange warnings of significant risk due to very heavy and persistent rains in the coastal areas of Cádiz, as well as in Huelva, the countryside of Seville and, until midday, on the coast of Valencia.
The yellow warning, which indicates moderate risk due to heavy rain, affects several areas of the country, such as lItoral north of Alicante, south of Ávila, north of Cáceres, the rest of the province of Cádiz, south of Castellón, the Sierra Norte of Seville and the interior of Valencia. Likewise, Meteorology has issued yellow warnings for coastal phenomena, with waves of four to five meters in A Coruña and two to three meters on the coasts of Almería and Granada.
The AEMET predicts that, throughout the day, lDANA will evolve into an isolated cold storm that will move to the southwest of the peninsula. Precipitation will mainly affect the southwest quadrant, the northwest, the southeast, the Levantine area, the Pitiusas and Canary Islands, although it is likely that it will also extend to surrounding areas. No rain is expected in the Cantabrian Sea, the upper Ebro, the northeast of the peninsula and Menorca. In some areas, especially in the west and south of Andalusia and in the Levant, the rains could be locally very strong or persistent, accompanied by storms.extending even to the Central System.
What is an Isolated Cold Storm (BFA)?
According to Meteored, the DANA will become a BFA (Isolated Cold Storm) after a cyclogenesis process occurs on the surface. From the meteorological information portal they explain that a BFA is a low pressure system that, when separated from the general atmospheric circulation, becomes “isolated” in a specific region. This phenomenon shares many characteristics with a DANA, but by being disconnected from the flow of the polar jet, uBFA can remain stationary in one area for several days. This significantly increases the risk of heavy rain and sometimes strong windsprolonging the adverse weather conditions in the affected area.
During the Fridaythe BFA would tend to remain quasi-stationary to the southwest of the Peninsula, with the highest probability of precipitation expected this day around the southwestern quadrant, mainly in the western end of Andalusia, where it is not ruled out that the showers will be locally very strongadvances the AEMET. In the Mediterranean slopeAlthough there could still be some rainfall, it would be much weaker and more dispersed. From Saturdaythe most probable scenario shows that rainfall would be restricted mainly to the western end of the peninsula while it would lose intensity.
Radical change in temperatures
As for temperatures, a general rise is expected on the peninsula this Thursday, being notable in some inland areas. Temperatures are expected to rise nine degrees in Ciudad Real, Jaén and Segovia; eight degrees in Palencia, Soria and Toledo; and seven degrees in Burgos, Córdoba, Granada, Guadalajara, Valladolid and Zaragoza. In Almería, León, Logroño, Murcia, Salamanca, Vitoria and Zamora, the increase will be about six degrees. The maximum temperatures will be recorded in Alicante and Almería, where they will reach 24 degrees, and in Las Palmas de Gran Canaria, Melilla and Santa Cruz de Tenerife, with 23 degrees. On the other hand, the minimum temperatures will be in Ávila (13 degrees) and in cities such as Burgos, San Sebastián, Santander and Segovia, with 15 degrees.
