The State Meteorological Agency (AEMET) warns that From today the “most adverse” part begins of this episode of heavy rains.

cold storm
According to the AEMET, it is likely that DANA will move towards the southwest until it is near the Gulf of Cádiz, while It will produce cyclogenesis at low levels, resulting in a drop in surface area around the southern coast of the peninsula between the afternoon and evening. In this way, DANA will “very likely” evolve into a cold storm.
As a consequence, an easterly wind will be established in the Mediterranean that will intensify on Tuesday, favoring the arrival of a large amount of humidity to the east of the peninsula. Very strong showers are expected without ruling out that they may reach torrential intensity locally.in addition to being persistent and accompanied by rvery strong wind blades.
As for the temperaturesa notable increase in maximum temperatures is expected in almost the entire country, with the exception of the Canary Islands, the Strait area and Empordà, where values will remain stable or even decrease. The minimums will rise in the center, east and Balearic Islands. In addition, snow is not ruled out in the Sierra Nevada.
How long is it going to rain?
The episode of heavy rain will continue until at least Thursday, although there is a possibility that it could be extended until Saturday. Tuesday is expected to be the “peak” day of this episode, with the highest probability of intense rainfall in the peninsular Mediterranean region, especially in the Valencian Community and Murcia, where more than 150 liters per square meter could accumulate in 24 hours.s. Precipitation is also expected around the Strait, although to a lesser extent in the center and south of the peninsula.
On Wednesday the areas with the greatest probability of intense and persistent rains be the west of Alborán, the Strait, the lower Guadalquivir and the northeast quadrant, mainly around Castellón and Tarragona. Meanwhile, the Cantabrian and Atlantic slopes, except the southwest of the peninsula, and the Balearic Islands, will be much less affected these days.
Starting Thursday, although uncertainty increases, the low pressure is likely to move towards Portugal, which would increase the probability of heavy rains in the south and southwest of the peninsula and in the Balearic Islands, and would reduce the intensity in the peninsular Mediterranean area.
