The State Meteorological Agency warns of the imminent arrival of storm Therese, an atmospheric phenomenon of great intensity that this Friday will discharge all its power over Spain.
The forecasts indicate that the isolated depression at high levels (DANA) will experience a process of explosive cyclogenesis, a technical term that meteorologists use to describe a very rapid deepening and that in colloquial language translates as an “explosion” of the storm.
The result will be a day marked due to the storm in large areas of the country, with special incidence in the Canary Islands, where the most severe effects are expected.
The Canary Islands will bear the brunt of Therese’s onslaught. From the early hours of Friday, the skies will remain overcast and rainfall will be widespread, becoming stormy in many areas and without ruling out the fall of hail.
The accumulated water will be very significant in large areas, But where the storm will show its most violent face will be on the islands of greatest relief. The southwestern slopes of La Palma, Tenerife and Gran Canaria They could register very strong rain intensities, exceeding the thresholds that usually activate maximum alerts.
In addition, the snow level will decrease until it is between 1,900 and 2,200 meters, covering the highest peaks in white. The wind will blow with very strong gusts from the southwest, adding another dangerous component to the situation.
The peninsula, under the growing influence of the storm
Although the center of the storm will be located near the Canary Islands, its field of clouds and precipitation will extend towards the Iberian Peninsula throughout Friday.
A cloud mass will advance from the southwest to the northeast, progressively covering most of the peninsular territory, with the exception of the extreme northeast and the Cantabrian coast, where the skies will remain clearer or with intervals of high clouds.
The rains will make an appearance in the middle southern peninsulain it west end and in the autonomous cities of Ceuta and Melilla. They will be more abundant during the first half of the day in the southwest, where they could become locally strong and leave significant accumulations in points of western Andalusia and in the west of the Alboran Sea.
In the afternoon, postfrontal instability could generate locally heavy showers in Galicia and the interior of Asturias.
The thermometer will also reflect the presence of Therese. Maximum temperatures will experience a general decline in the peninsula, especially pronounced in areas of the central west.
On the contrary, in the northeastern third they will remain unchanged or even with slight increases, and in the Canary Islands they will rise due to the dynamics of the storm.
The minimums, for their part, will rise in the northwest quadrant peninsular and on the islands, while they will decrease in the northeast. The frosts will be limited to the Pyrenees and, locally, to parts of Iberia.
The wind will blow from the east, with light to moderate intensity in the interior of the peninsula, but reaching warning strength on the southeastern coasts and in Alborán, where winds are expected. very strong gusts which could also occur on the coast of Cádiz. In the Balearic Islands, the moderate northeast wind will predominate, and in the Canary Islands, as has been noted, the southwest will blow with very strong gusts. throughout the day.
