The 18 districts of the mainland are under yellow warning (until 9 p.m. on Monday) due to the forecast of rainfall sometimes strong and persistent and IPMA also issued the same warning for the entire Portuguese coast, but because of rough seas (until noon on Tuesday).

IPMA issued the yellow warning to the districts of Bragança, Viseu, Guarda, Vila Real, Viana do Castelo, Braga and Castelo Branco due to the forecast of snowfall above 1400/1600 metres, gradually lowering the snow line to 800/1000 metres, between 3 p.m. on Monday and 3 a.m. on Tuesday.

The districts of Viseu, Évora, Guarda, Faro, Beja, Castelo Branco, Coimbra and Portalegre are under yellow warning because of the strong wind with gusts up to 80km/h, between 9 a.m. and 6 p.m. on Monday.

The yellow warning is the second least serious on a scale of four and is issued when the weather conditions represent a "risk for certain activities".

The bad weather felt in Portugal mainland follows the passage of the depression "Daniel" which is associated with a swell of the cold front surface that crossed the country.

Given the scenario of heavy and persistent rainfall, the civil protection warned that special attention should be given to areas historically identified as vulnerable to flooding and in unregulated river basins with rapid flow.

The authorities also warned of the possibility of branches or trees falling due to stronger wind and possible accidents on the coastline, and the parking of vehicles in these areas should be avoided.
