Memorable will be the rainfall event that the extratropical cyclone will bring to the south-central area of the country. Check the meteorological details that are projected for the coming days and the regions most affected by the rains.
The enormous extratropical cyclone, which began to develop last week over the Pacific Ocean, will give rise to several pulses of precipitation in our country over the next few days.
Considering the update and meteorological analysis of our reference model from the European Center for Medium and Long-Range Forecasts (ECMWF), the first of these pulses of precipitation will begin at dawn Tuesday 04 between the regions of La Araucanía and Aysén, and will decline during that day.
But, so far, the pulse of precipitation The most intense is forecast from the navel of the week. In fact, this Sunday the 2nd, the Chilean Meteorological Directorate (DMC) issued an alert for moderate to heavy precipitation with a high 0 °C isotherm.
This weather alert is valid for regions of Maule, Ñuble and Biobío between the morning of Wednesday the 5th and the night of Thursday the 6th, a period in which they will also be registered Wind gusts around 50 km/h.
Abundant rains with high zero isotherm and atmospheric river will bring the extratropical cyclone to Chile during this week
In this direction, prevention is necessary in the event of emergencies generated due to the predicted amounts of water fall. For example, between Wednesday and Thursday 65 mm could accumulate in the valley and mountain range of the Maule Region.
During this second pulse of precipitation, the amounts of fallen water could exceed 90 mm in the Andes mountain range between the regions of Ñuble and Biobío.
This meteorological condition is associated with the fact that the 0 °C isotherm It would be located at a minimum of 2,800 meters above sea level (masl), in the aforementioned geographic section, causing more liquid precipitation in sectors where snow should be recorded.
It is worth mentioning that the rains of this second pulse will extend to the Magallanes Region.
To all this “weather cocktail” We must add an ingredient, of which we have already seen its effects in Chile during the winter of 2023. We are referring to an atmospheric river that, this time, it would land in category 4 -on a scale that goes from 1 to 5- between the Biobío and Los Ríos regions.
Starting Thursday night, a third pulse of precipitation would arrive to the south of Chile, mainly, from the Biobío Region to the Aysén Region. The rains would extend to the regions of Ñuble and Maule in the afternoon hours of Friday.
In fact, rainfall would continue to intensify during the weekend with the probability that they will arrive in the central zone on Sunday the 9th. So Watch out for upcoming weather updates!
