Alert for heavy storms in a large part of the country tomorrow
Extensive spell of showers and thunderstorms this Thursday, with a temporary drop in temperatures
BarcelonaThe calm of this Wednesday will not continue. This Thursday instability will clearly increase, and from midday and during the afternoon an extensive spell of showers and strong storms is expected that will sweep across a large part of the country. Not yet in the morning, when calm will dominate, although variability and clouds will be increasing as the hours go by.
Precipitation will start punctually in the Pyrenees and Pre-Pyrenees, where the first shower may appear before noon. Storms will quickly spread in the afternoon towards Central Catalonia, and showers will eventually reach a large part of the interior and pre-coastal areas, especially the central ones, as well as the Ports. Some showers will also reach the coast, especially between Maresme and Camp de Tarragona, although they will initially be more scattered and less intense. It will be less likely to rain in the northeast of the Girona region and between the south of Camp de Tarragona and the Ebro coast.
Storms will in many cases leave authentic downpours, accompanied in some cases by hail, sleet or strong winds. Extreme phenomena that will be fueled by so much accumulated heat this summer. The most affected areas will be Central Catalonia, the eastern Pyrenees and pre-Pyrenees, the Barcelona coast and the interior of Camp de Tarragona. The Inuncat plan is activated in alert phase, and Meteocat's warnings for heavy rain extend over a large part of the country. In addition, in the most affected areas, the new alert for accumulations of more than 60 l/m² in just three hours has also been activated.
Given all this, Civil Protection asks to exercise extreme caution, especially regarding mobility and outdoor activities, particularly in areas where rapid water accumulations or sudden flash floods in streams and torrents may occur. Downpours can also occur inland in the counties of Girona and Valencia.
All this will cause a drop in temperatures, especially where it rains heavily. Therefore, more bearable heat is expected, with many highs between 29 and 34°C. The change will be barely noticeable on the coast, where thermometers will remain similar to Wednesday's and the mugginess will continue to be significant.
More heat in the coming days
The showers will decrease in the coming days, but they will not disappear. On Friday, there will be remnants of instability in the Pyrenees and the northeast, and on the weekend, afternoon showers and thunderstorms will increase again in the north of the country.
However, the degrees lost on Thursday will be recovered on Friday and during the weekend. Therefore, we will continue with temperatures clearly above average, with marked heat and mugginess. Next week could be particularly warm again, as the North African warm bubble would be reinforced.
