TIME 4:30 PM






According to information from the Portuguese Institute of the Sea and Atmosphere (IPMA), precipitation, wind, sea agitation and snowfall are expected for the next 72 hours, with emphasis on the following:

  • Precipitation, sometimes heavy and persistent, which may be hail and accompanied by thunderstorms, from Wednesday, March 27th;
  • Wind, sometimes strong, in the highlands and on the west coast with gusts of up to 80km/h, in the late afternoon of March 25th. Wind with gusts of 100 km/h in the highlands, especially in Serra da Estrela, on March 26th. Predominant wind from the southwest, with gusts of up to 85 km/h from the afternoon of March 27th, in the North and Centre regions, and may exceed 90 km/h in the highlands;
  • Strong sea disturbances with waves from the northwest on the west coast, worsening during the afternoon of March 26th, reaching 6 to 7 meters north of Cape Carvoeiro (maximum height of 12 meters);
  • Snowfall in the highlands, especially in the North and Centre, gradually dropping to 600/800 meters, and snowfall may also occur in the São Mamede and Monchique mountains, in the early hours and morning of March 26 .

Given the change in weather conditions, with forecasts of precipitation, wind, sea disturbances and snowfall, the following is expected:

  • Slippery road surfaces due to the possibility of accumulation of ice, snow and formation of water tables;
  • Possibility of snowfall in areas and at altitudes where it does not usually occur;
  • Drainage difficulties in urban systems, particularly those seen during periods of high tide, which can cause flooding in historically more vulnerable locations;
  • Possible accidents on the coast due to strong sea waves;
  • Occurrence of flooding in urban areas, caused by accumulation of rainwater due to obstruction of drainage systems or coastal overtopping;
  • Possibility of falling branches or trees, as well as affecting infrastructure associated with communications and energy networks;
  • Damage to mounted or suspended structures;
  • Thermal discomfort in the population due to the sharp drop in minimum temperature.



The National Emergency and Civil Protection Authority (ANEPC) recalls that the impact of these effects can be minimized, mainly through the adoption of appropriate behaviours, therefore, and particularly in historically more vulnerable areas, it is recommended to adopt the main preventive measures to these situations, namely:

  • Ensure the unblocking of rainwater drainage systems and the removal of aggregates and other objects that could be dragged or create obstacles to the free flow of meltwater;
  • Pay attention to the most vulnerable groups (children in the first years of life, chronically ill people, elderly people or people in conditions of greater isolation, workers who work outdoors and homeless people);
  • Ensure adequate fixation of loose structures, namely scaffolding, billboards and other suspended structures;
  • Take special care when traveling and staying near wooded areas, paying attention to the possibility of falling branches and trees, due to stronger wind;
  • Take special care when traveling near the coastline and riverside areas that are historically more vulnerable to coastal overtopping, avoiding movement and staying in these places;
  • Do not practice activities related to the sea, namely sport fishing, water sports and walks by the sea, also avoiding parking vehicles very close to the seafront;
  • Adopt defensive driving, reducing speed and paying special attention to possible accumulation of snow and/or formation of water tables on roadways;
  • Avoid driving on roads affected by snow accumulation and when this is not possible, adopt the following measures:
  • Checking the condition of the tires and their pressures;
  • Transport and placement of snow chains on vehicles;
  • Ensure fuel supply at levels that allow alternative routes to be taken or the vehicle to remain in operation for long periods of time, in the event of stranding on affected roads;
  • In electric vehicles, the battery charge must be checked and the existence of charging stations on your route must be analysed;
  • Ensure that vehicle heating systems are in good working order;
  • Provide adequate food in quantity and characteristics, as well as medicines, according to the number and type of vehicle occupants.
  • On roads affected by snow accumulation, avoid traveling with children, the elderly or people with special needs;
  • Avoid driving on those roads with heavy vehicles, particularly articulated vehicles, vehicles with trailers and rear-wheel drive vehicles;
  • Restrict the movements of vehicles and people on foot as much as possible in areas potentially affected by snowfall;
  • Do not cross flooded areas, in order to prevent people or vehicles from being dragged into holes in the pavement or open sewage tanks;
  • Pay attention to meteorological information and indications from Civil Protection and Security Forces.
