According to forecasts from the Institute of the Sea and the Atmosphere (IPMA), the week from January 30 to February 5 will be marked by "cold weather associated with a predominant east or northeast flow", favouring the "formation of frost and/or or ice associated with the sharp nocturnal cooling", and the formation of mist or fog, particularly with regard to northeastern Transmontano and Alto Douro.
According to the body, the maximum temperature should reach values between 5 and 16°C throughout the week. In turn, the minimum temperature will vary between -6 and 8°C, "with the lowest values expected for the interior North and Center regions".
"For this week, the anomaly of total precipitation and the average temperature will remain below normal, starting the week with a small decrease in the minimum temperature compared to the previous weekend (28th and 29th)", points out also the entity.
The IPMA issued a yellow warning for all districts on the mainland for Saturday and Sunday due to the persistence of low minimum temperature, which should be renewed next week, according to meteorologist Madalena Rodrigues.
