What began as another bright summer day began to get dark in the afternoon. Gradually, but steadily, large clouds of smoke spread to cover much of the capital from 5:00 p.m. The reason? Three forest fires and an urban fire that coincided during the day.
The main focus was on Cuncumén, a town in the commune of San Antonio and 80 kilometers from Santiago. As reported by the National Forest Corporation (Conaf), the fire had destroyed until Monday at 7:30 p.m., more than 200 hectares of pastures, bushes and eucalyptus trees. The spread was particularly rapid due to prevailing winds in the area.
In the same region of Valparaiso, another forest fire that burned since last Saturday in the outskirts of Lo Vásquez was extended to 253 hectares and maintained until Monday active hot spots.
Another contributor to the immense cloud of capital smoke lay to the south, in the sector of Angostura, near San Francisco de Mostazal. The fire had consumed, until tonight, 50 hectares.
One factor that affected the accumulation of smoke in the city was the wind. Alonso Guajardo, a specialist in the Chilean Meteorological Administration, explained that at 7:20 p.m., at the station located in Lo Prado, the winds showed a westerly direction and a speed of 40 km / h. The measurements that El Paico station was launching in the municipality of El Monte indicated winds of 30 km / h, also to the west. Together with the presence of the Cordillera Cordillera Coastal, they generate a Venturi effect that "sucks" the smoke-laden air into the city.
Inside the city, a disaster unleashed on the premises of an automobile company located in San Ignacio with Pedro Lagos, generated a visible smoke column from different points of the capital.
The fire, which caused an evacuation of 400 people from a building, increased the flow of pollution. 22 units of fire fought against the flames, which were controlled before midnight.
Until this night, Conaf conducted a total of 12 forest fires between the regions of Valparaíso and La Araucanía.
