BarcelonaA small upper-level trough will finish crossing our latitudes during the early morning and morning of this Monday, and will destabilize the weather throughout the territory. Thunderstorms have discharged in counties of the Pyrenees and Pre-Pyrenees, with more abundant amounts in Berguedà, northern Osona or Ripollès where 10 to 20 l/m² have accumulated in a few minutes (27 l/m² in Orís and 20 l/m² in Cantonigròs, until 8 PM on Sunday). With the passage of this line of instability, the weather will improve, in a week that is expected to be calmer and with a clear recovery of thermometers.

You will find a list of accumulated rainfall observations at the end of this information.
