The National Emergency and Civil Protection Authority (ANEPC) issued a warning to the population on Thursday, for the next 24 hours, of heavy rain in the north and central coastal regions, wind, and snowfall above 1,400 meters in altitude.
The warning was based on forecasts from the Portuguese Institute of the Sea and Atmosphere (IPMA) which reports "rainfall, sometimes strong and persistent, in the regions of the north and central coast, especially in the Minho and Douro coast, progressing towards the south and the possibility of ice and frost formation in the northern and central interior of the country.
The IPMA also estimates the possibility of snowfall above 1400 meters of altitude, wind intensifying from the southern quadrant, with gusts of up to 70 km/hour in the northern coastal strip of Cabo Raso and in the highlands and waves from the northwest with four to five meters on the north and central coast.
The orange warning is the second most serious on the scale and is issued in "moderate to high-risk meteorological situations", according to IPMA.
The yellow warning is issued by IPMA whenever there is a risk situation for certain activities depending on the weather situation.
