Catalonia will start Tuesday under the influence of an instability line that will be felt from midday. According to forecasts, a significant activation of showers and storms is expected to affect different parts of the territory. May continues, and with it the instability of a spring that is being especially wet.
As the day progresses, convection will advance in areas of the interior and north of the Catalan territory. All of this with storms that could be locally intense and accompanied by hail. The most affected regions by this episode will be those of the Pre-Pyrenees and Pyrenees, where convective cores will reach greater intensity.
Precipitation could exceed 0.8 in. (20 mm) per hour in some areas, with added risk of hail. Especially in mountain areas like Alt Urgell, Cerdanya, Ripollès, and Berguedà. Notable storm activity is also expected in points of the extreme south of the territory, especially in the interior of Les Terres de l’Ebre.
Catalonia keeps its unstable pattern
In contrast, the central coast and pre-coastal areas, including the metropolitan area of Barcelona, will receive less impact. The storms in these areas will be much weaker, if they form at all, and are not expected to cause significant incidents. However, caution is recommended due to the variability of these situations.
This episode is linked to the persistence of an anticyclonic block in northern latitudes, which keeps the doors open to the entry of cold air to the northeastern peninsula. This configuration, which has been repeated in recent weeks, favors a more unstable weather pattern in Catalonia. This translates into frequent rains and temperatures below what is usual for this time of year.
Storms and hail will continue to be the main features
The situation will continue until Wednesday, with a slightly cooler environment and the possibility of intermittent showers. Despite this spring pause, experts warn that intense heat will not take long to arrive. But for now, the main features will continue to be the storms.
Authorities recommend staying alert to weather updates, especially in the interior and northern regions of the territory. It is there where storms could be accompanied by adverse phenomena such as hailstorms, strong wind gusts, or rapid water accumulations. Therefore, there is no choice but to keep being patient and enjoy all the good things that water also brings.
