NOTICE TO THE POPULATION
RAIN AND WIND – PREVENTIVE MEASURES
NATIONAL EMERGENCY AND CIVIL PROTECTION AUTHORITY
According to information made available today by the Portuguese Institute of the Sea and the Atmosphere (IPMA), precipitation is expected for the next few days, sometimes heavy, especially on the central and southern coast, extending to the entire territory:
13th Sep. – Monday− Showers, sometimes heavy, accompanied by thunderstorms, especially on the west coast and the Algarve, gradually extending to the other regions from the afternoon onwards;
− Probability of extreme wind phenomena;
− Light to moderate wind (up to 30 km/h) from the southern quadrant, blowing moderate to strong (30 to 45 km/h) in the highlands, especially from the centre and south, sometimes with gusts up to 80 km/h.
14th Sep. – Tuesday− Showers, sometimes heavy, accompanied by thunder, hail and gusts of strong wind;
− Light to moderate wind (up to 30 km/h) from the southern quadrant, blowing moderate to strong (30 to 40 km/h) in the highlands of the Center and South.
− Lowering of the maximum temperature.
Given the forecasts of heavy and persistent rainfall in the aforementioned regions, floods and floods may occur in urban areas, especially in the metropolitan area of Lisbon and in the city of Setúbal.
There is also the risk of rising water levels in the Algarve’s rivers and streams, which could cause flooding in more impermeable urban areas. It is recommended that special attention be paid to the possible combination of rainfall peaks with the hours forecast for high tide.

2. EXPECTED EFFECTS
Given the forecast weather situation, the following effects may occur:
− Slippery road surfaces and possible formation of rising water tables;
− Possibility of rapid floods in urban areas, due to accumulation of rainwater or insufficiencies of drainage systems;
− Possibility of flooding by overflowing water lines in historically most vulnerable areas;
− Flooding of underground urban structures with drainage deficiencies;
− Damage to mounted or suspended structures;
− Draining difficulties in urban systems, namely those verified in periods of high tide, which can cause flooding in historically more vulnerable places;
− Possibility of falling branches or trees due to stronger wind;
− Possible accidents on the coastline.
3. PREVENTIVE MEASURES
ANEPC recalls that the possible impact of these effects can be minimized, especially through the adoption of appropriate behaviours, for which, and particularly in historically more vulnerable areas, it is recommended to observe and disclose the main self-protection measures for these situations, namely:
− Ensure the unblocking of rainwater drainage systems and removal of inert materials and other objects that may be dragged or create obstacles to the free flow of water;
− Adopt defensive driving, reducing speed and taking special care with the possible accumulation of snow and formation of water sheets on the roads;
− Do not cross flooded areas, in order to prevent falling (people or vehicles) into holes in the pavement or open sewer boxes;
− Ensure adequate fixation of loose structures, namely scaffolding, placards and other suspended structures;
− Take special care when circulating and staying close to wooded areas, being aware of the possibility of falling branches and trees due to stronger winds;
− Take special care when traveling along the coastline and historically more vulnerable riverside areas;
Be aware of meteorological information and indications from the Civil Protection and Security Forces.
