BarcelonaThe 'Adam' DANA and the arrival of humid sea winds have caused very intense storms in the last few hours, with accumulations that in some cases have exceeded 50 or 60 mm and have set some precipitation records (you will find more data at the end of this report). The weather will remain unsettled this Sunday, with widespread but less intense rain, good news for watering many regions in a more gradual way, without the downpours that have affected us regularly this month of October.

Weather forecast for this Sunday morning.

Sunday: gray and cold day

What we are already noticing this Sunday morning is a sharp drop in temperatures. The atmosphere will be generally cold, with many highs of only 13°C to 17°C, but clearly lower in mountain areas. On the coast, it will not reach 20°C. A sudden feeling of late autumn and values below what would be expected for this time of year. The decrease in highs may in some cases be up to 10 degrees compared to days ago.

All this with weather that will remain quite unsettled. Gray skies are expected across the territory, with a risk of rain anywhere. There is still some uncertainty about the final distribution of the precipitation, a classic in these Mediterranean autumn situations. There will be a risk of some downpours, especially between Tarragona and Barcelona, but in general, we will be talking about very well-timed rain.

Weather forecast for this Sunday afternoon.

Attention to the Valencian Community and the Balearic Islands, where rainfall will be heavy and abundant, with a risk of torrential downpours and significant accumulations. AEMET has issued a red warning for the southern coast of Valencia and the north of Alicante due to 24-hour accumulations of between 200 and 300 mm. There are also alerts activated for rainfall intensity.

Monday: more rain

The week will begin with still very unstable weather and locally intense precipitation that will advance from the sea towards land, with humid maritime winds that will help to maintain this unsettled weather situation. The rain will be locally intense in parts of the coast and pre-coastal areas, but also in some inland regions, with storms and new downpours in areas that have already received a lot of water since the beginning of the month. The minimum temperature will drop a little more, but the maximum will remain stable and the environment will be cool at midday.

Assessment of a new episode of downpours

The rain started to fall in parts of the northeast during Saturday afternoon, and as the hours passed, it spread to more areas, always more intense along the coast and pre-coastal regions. In some places, such as the Port of Barcelona, Sant Pere de Ribes (Garraf), or Cabrils, over 70 mm have been exceeded between Saturday and Sunday. In fact, in Cabrils and Sant Pere de Ribes, more than 60 mm fell in just thirty minutes, an exceptional intensity of precipitation in the country. In the case of Cabrils, the 37.8 mm that fell in 10 minutes is a new rainfall record for this time period in Catalonia.
