The whole of Portugal has been placed on yellow alert today due to a forecast of heavy rain accompanied by thunderstorms and strong winds gusting to 80 km/h along the coast, and 100 km/h inland.
In the Algarve the warning includes high seas with southeasterly waves of 2 to 3 metres along the south coast.
According to Bruno Gonçalves of the Algarve Meteofontes website, there is "a somewhat complex situation in the Atlantic with a depression and cooler air northwest of the continent moving to the south-east and a depression in the Madeira area moving towards the continent."
"The interaction between these two depressions will result in one, that will intensify near our coast so the weather will be poor this weekend."
The meteorologist said that "the analysis of the various models shows we have a relatively normal situation for this time of year, or a slightly worse one than usual. This will largely depend on the result of the merging of the two depressions and the shape and exact location where this happens, so monitoring by radar and satellite imagery is needed to confirm what actually will happen.”
The yellow warning has been activated as worsening weather is expected with the possibility of periods of strong and persistent rain and some thunderstorms, mainly in the Central and Southern regions with a peak at around lunchtime."
The wind will be a moderate to strong southerly with gusts to 80 km/h along the southern and central coast and 100 km/h in inland areas. At sea, the waves will increase to 3 metres in the southeast and south coast and to 3.5 metres in the southwest and along the west coast.
Sunday will see cloudy skies and periods of heavy rain and thunderstorms, mainly in the afternoon with rain persisting until Tuesday.
