The districts of Vila Real, Bragança, and Guarda are under yellow art on Monday and Tuesday due to the extremely cold weather, according to the Instituto Português do Mar e da Atmosfera (IPMA). The yellow alert ends at 9 am on Tuesday for the three districts. These districts have reached negative temperatures, with Saturday having been the coldest day with temperatures reaching -2ºC.
The IPMA told CNN that the cold temperatures are a result of a polar air mass arriving in Portugal, as well as other European countries. The cities of Lisbon and Porto are not heavily affected as temperatures in these cities remain mild.
A yellow alert has also been applied to Faro until Tuesday at 3 pm due to rough waters. Waves of 2 to 3 meters are predicted in the district.
The North coast of Madeira and Porto Santo are also expecting waves of 4.5 meters and are under yellow alert until Monday at 6 pm. The more mountainous regions of Madeira were on yellow alert until today at 12 pm due to winds of 95 kilometers an hour.
A Yellow Alert means that the weather conditions represent a risk for certain activities. Essentially, it means residents need to be careful during the alert period.
