ADVERSE METEOROLOGICAL CONDITIONS – PERSISTENT PRECIPITATION

 

  1. SITUATION

Weather situation:

Following the contact with the Portuguese Institute of the Sea and Atmosphere (IPMA), held today, November 10, by the National Civil Protection Authority (CNPC) of the National Civil Protection Authority (ANPC), and according to the information weather forecast is expected to worsen on Sunday (11Nov), namely persistent precipitation, with a more critical period between 00h01 and 23:59 on November 11 (Sunday).

From the end of the afternoon of November 9, Friday, and until the end of day 11, Sunday (including also the night of November 11th to 12th in the Lower Alentejo and Algarve), the weather in the territory of the continent is influenced by a zonal current which is associated with a very humid tropical mass of air, which is responsible for persistent, and sometimes strong precipitation.

In addition, on the 11th, a valley is approaching at the high levels of the troposphere, which may give rise to an unstable atmosphere, essentially in the southern regions of the Montejunto-Estrela mountain system, where occasional thunderstorms may occur.

Considering the current meteorological situation, the ANPC, through CNOS, of the District Commands and in close articulation with the relevant agents of the Civil Protection System, we are monitoring  the basins of Cavado, Douro, Vouga, Mondego, Tejo and Ribeiras do Oeste .

 

  1. EXPECTABLE EFFECTS

In view of the situation described above, the following effects may occur:

  • slippery road surface and possible formation of surface water;
  • Possibility of rapid flooding in urban areas, due to the accumulation of rainwater or insufficient drainage systems;
  • Possibility of flooding by transhipment of water lines in historically more vulnerable areas;
  • Floods of underground urban structures with drainage deficiencies;
  • Drainage problems in urban systems, especially those occurring during periods of high tide, and may cause flooding in historically more vulnerable areas;
  • Possible accidents in historically flooded areas;
  • Geomorphological phenomena caused by unstable slopes associated with soil saturation, by the loss of their consistency
  • Obstruction of roadways by falling trees, landslides or landslides, stones or other structures;

 

  1. PREVENTIVE MEASURES

The ANPC reminds peoples that the possible impact of these effects can be minimized, especially through the adoption of appropriate behaviour, and therefore, and in particular in the most vulnerable areas, it is recommended to observe and disseminate the main self-protection measures for these situations, namely:

  • Ensure clearing of rainwater drainage systems and removal of aggregates and other objects that may be dragged or obstruct the free flow of water;
  • Do not cross flooded areas, so as to prevent the entrainment of persons or vehicles to holes in the pavement or open sewage boxes;
  • Adopt a defensive driving, reducing the speed and taking special care with the possible formation of surface water on the roads;
  • Remove agricultural, industrial, vehicle and other property from confined areas, normally flooded;
  • placing animals in safe places, removing herds from areas likely to be flooded;
  • Be alert to meteorological information and Civil Protection and Security Forces indications, developing the necessary actions for your protection, family and property.

  1. SITUATION

Meteorological situation:

 

Following the contact with the Portuguese Institute of the Sea and Atmosphere (IPMA), held today, November 8, by the National Civil Protection Authority (ANPC), and according to the information forecast for the next few hours there will be a worsening of the weather conditions, with a more critical period between 12 noon tomorrow, 9 November and 0600 hrs on 10 November, in particular:

  •  Wind from the south quadrant moderate to strong on the coast from the afternoon, with gusts in the order of 85 km / h, especially in Minho and Douro Litoral. In the highlands the wind will blow moderate to strong (<40 km / h), intensifying from the afternoon (<50 km / h) with gusts up to 100 km / h, especially in the Minho region.
  •  Sea turmoil on the west coast and on the south coast with northwest waves between 4 and 5 meters high.

EXPECTED AFFECTS

 

In view of the situation described above, the following effects may occur:

  • slippery road surface and eventual formation of surface water;
  • Possibility of rapid flooding in urban areas, due to the accumulation of rainwater or insufficient drainage systems;
  • Possibility of flooding by transhipment of water lines in historically more vulnerable areas;
  • Floods of underground urban structures with drainage deficiencies;
  • Damage to mounted or suspended structures;
  • Drainage problems in urban systems, especially those occurring during periods of high tide, and may cause flooding in historically more vulnerable areas;
  • Possibility of falling branches or trees due to stronger wind;
  • Possible coastal shoreline accidents.
  • Landslips caused by instability of slopes associated with soil saturation, by the loss of their consistency
  • Obstruction of roadways by falling trees, landslides or landslides, stones or other structures;
  1. PREVENTIVE MEASURES

The ANPC reminds people that the possible impact of these effects can be minimized, especially through the adoption of appropriate behaviour, and therefore,  in particular in the most vulnerable areas, it is recommended to observe and disseminate the main self-protection measures for these situations, namely :

– Ensure clearing of rainwater drainage systems and removal of aggregates and other objects that may be dragged or obstruct the free flow of water;

– Do not cross flooded areas, so as to prevent the entrainment of persons or vehicles to holes in the pavement or open sewage boxes;

– Adopt a defensive driving, reducing the speed and taking special care with the possible formation of surface water on roads;

– Ensure adequate fixing of loose structures, namely scaffolding, placards and other suspended structures;

– Take special care in passing by and staying near wooded areas, being aware of the possibility of a fall of branches and trees, due to a stronger wind;

– Take special care in the passing by coastal and riverside areas historically more vulnerable to coastal gullies, avoiding if possible travelling and staying in these places;

– Do not engage in activities related to the sea, namely sport fishing, water sports and walks by the sea, avoiding the parking of vehicles very close to the seafront;

– Avoid travelling and staying in the highlands where the expected gusts of wind are strong or very strong;

– Be aware of meteorological information and Civil Protection and Security Forces indications.
