Depending on present and predicted weather conditions, it is expected:
- Slippery roads and possible flooding;
- Possibility of rapid flooding in urban environment, due to rainwater accumulation or inadequacy of drainage systems;
- Possibility of flooding by transhipment of water lines in historically most vulnerable areas;
- Flooding of underground urban structures with drainage deficiencies;
- Drainage difficulties in urban systems, in particular those in pre-sea periods, may cause flooding in the most vulnerable historically places;
- Damage to mounted or suspended structures;
- Possibility of falling branches or trees as well as allocation of infrastructure associated with communications and energy networks.
The ANEPC recommends that the population take the necessary prevention measures, in particular:
- ensure the clearance of rainwater systems and removal of items 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 of possible formation of water sheets on roadways;
- do not cross flooded areas to prevent falling into or vehicles becoming lodged in pavement holes or open sewage boxes;
- be careful in circulating and staying in wooded areas, paying attention to the possibility of falling branches or trees in stronger wind places;
- take special care in circulation along the coastal areas and areas historically more vulnerable to these conditions;
- be mindful of weather information and Civil Protection and Security Forces indications.
