The goosebowl comes: a pre -warning
The Borrasca Jana has been officially named by the State Meteorological Agency (AEMET) at a time when the forecasts indicate a drastic change in the weather conditions in Barcelona and other regions of Catalonia. This situation is expected to take place over the weekend, carrying intense winds, high waves and precipitation.
Beyond the storm: the current rains
Although the Aemet has identified the Spanish storm, the rains that will fall on Thursday and Friday are not attributable to this phenomenon. In fact, these precipitation is the result of a east and xaloc wind corridor that have been formed between a high pressure on the Balkans and a low that is being developed in North Africa.
Evolution of the storm
It is expected that the Jana storm is considerably deeper, near the Galician coast. From Friday, the effects will be palpable on the peninsula, with alerts due to adverse conditions such as strong winds and dangerous waves, in particular affecting the northwest areas.
An active climate front
A frontal front linked to the Borrasca Jana promises a significant change in the climate of Catalonia. This front is expected to arrive between Saturday afternoon and Sunday morning, triggering a new wave of rains.
Rain and storm expectations
It is estimated that the front will cause an episode of rainfall, which could include storms and strong winds of wind, especially in the interior regions. Intense rain is expected to begin to fall on Saturday afternoon, with significant accumulations that could affect the heads of the rivers.
Alerts of the Meteorological Service
The Meteorological Service of Catalonia has issued warnings for the intensity of rain and wind, with the possibility that some areas of the northeast receive more than 100 liters per square meter. Wind conditions can also exceed 90 km/h in the Pyrenees.
Futuristic perspectives
Although the most active front is expected to leave before noon on Sunday, there is evidence that the Jana storm will continue to generate instability. However, current models do not foresee any significant rainy episode after this weekend.
