New and extensive area of low pressure will be positioned off Chile
Weekly trend forecasts tell us that a large cyclonic area (low pressure) will be located again this week off the coast of Chilefavoring the arrival of new front bands to the country.
This extensive low pressure center —also referred to as extratropical cyclone— will arrive in Chile quickly, after a very brief and almost imperceptible pause, following the frontal system that acts this weekend over the continent.
Unlike the extratropical cyclone that governed the weather conditions last week, the new low pressure will not be stationary, and It will cross the country between Tuesday (11th) and Thursday (13th).

Although the atmospheric river will present sectors with extreme and exceptional intensity —category 4 and 5 respectively, the highest in the classification— over the center of the country, the Coquimbo Regionas well as the regions of Araucanía to the souththey would receive mainly beneficial impacts.
The great low pressure and the atmospheric river will be responsible for leaving lrains between the regions of Atacama and Aysénconcentrated with more intensity between days Wednesday and Thursday of next week.
The precipitation What will this great system provide? They will be solid on the mountain rangesince it will be associated with a much colder air mass, with a zero degree isotherm that will move between the 1,800 m in the south of the country and 2,400 m in the central north.
