From Thursday, in addition to heavy rain and strong wind, sea disturbances are also expected due to storm Karlota, putting mainland Portugal under a yellow warning.
The yellow rain warning is in force for 18 districts of Portugal, between 3pm and 9pm on Thursday 8th February, plus an orange warning for Porto, Viana do Castelo and Braga between 12:00 and 18:00 on Thursday.
The districts of Faro, Setúbal, Lisbon, Leiria, Beja, Aveiro and Coimbra will be under yellow warning due to the state of the sea until 06:00am on Saturday.
According to a statement from IPMA , “this depression is part of a complex depression system, with two nuclei, which is evolving into just one nucleus, which will be located southwest of Ireland”.
The depression has an associated cold frontal surface and it will be this front that will affect mainland Portugal from Thursday onwards.
The change in the weather begins to be felt this Wednesday with light rain, especially in the North and Center regions, and with the wind intensifying from mid-afternoon.
