The passage of a trough in medium and high levels of the troposphere along with the presence of abundant humidity is leading to the formation of storms “that will be very efficient when leaving precipitation,” the State Meteorology Agency (AEMET) explained this Sunday at the last minute. The agency maintains a special notice for rains watered for red notices in areas of southern Catalonia and the Valencian Community, and insists that this Monday and this Tuesday and this Tuesday “They will be the most adverse days of the episode.”
The night has already been complicated in various points in Castellón, as well as Aragon, despite the fact that red warnings were not decreed there. Neighbors of the northeastern peninsular have shared spectacular images of how heaven has downloaded furiously over their neighborhoods and towns, and some rainfall of regions such as La Plana Low They have already registered more than 150 liters per square meter In the early hours of this Monday, September 29. The situation is expected to stay that way. In the early hours of the day several static nuclei were developed, which made the situation complicated in cities such as Castellón de la Plana or Benicarló.
The problem will be precisely that: the big difference of this episode of storms and rainfall abundant rains in areas where these floods take place“In any case, the Aemet does not rule out that they can be grown up from channels and that is why he calls” extreme caution and avoid ramblas and ravines. “
The Aemet expects torrential rains with accumulated that could exceed 180 liters per square meter in 3 or 4 hours in the south of Tarragona or the north of the Valencian Community. In the province of Valencia, up to 180 liters per square meter can be accumulated in less than 12 hours, and 300 liters per square meter or more throughout the entire episode, which implies that floods or sudden floods of channels could occur.
For having reference: between two and fifteen liters per square meter at the time it is considered that the rain is moderate. From 15 liters of water per square meter at the time is when it is considered that an episode of rainfall can Putting risks for goods or people.
This is not here. The situation will be equally complex for the early hours of this Tuesday, where also a good part of the storms formed will end up arriving in the Balearic Islands where you can see equally intense situations. “It is difficult to specify the areas in which the rains will be more intense,” clarifies the Aemet, so “it is highly recommended to be informed of the situation of time and follow the civil protection recommendations.”
In the rest of the country
They are also expected Chubascos in Eastern Andalusia and Balearic Islandswhere it is not ruled out that they are locally strong, while in the Cantabrian and in the northern Canary Islands a cloudy environment with weak and scattered rains will dominate. The rest of the Peninsula will enjoy a more stable time, with cloudiness intervals but in general without rainfall.
For the rest, the day on Monday will begin with morning fog banks in different parts of the Thirds North, East and South, reducing visibility remarkably. As for temperatures, a clear contrast is expected: They will rise in Girona and in good part of the Atlantic aspect (locally notable inside its southern half), while they will descend in the archipelagos, in the Eastern Cantabrian and inside the east peninsular, with significant falls in these last areas. The minimums will also go down in the Balearic Islands, the Eastern Facade and the Northern Peninsular Half, maintaining without major changes in the rest.
The wind will blow with a changing basis: from west in the Strait and Alborán, and southwest in the coastlines of the Southeast, with intervals of strong. In the Levante, northeast of the northern plateau, east of the south, Western Cantabrian and Galicia will be imposed by the winds of north and east, moderate and with strong gusts on the Galician coast. In the rest they will be lazy in general, while in the Canary Islands the Alisio will dominate, with strong intervals in exposed areas.
