That cold air is expected to move throughout the central portion of the country, generating rainfall of varying intensity between Tuesday and Wednesdayfor later settle over the center of Argentina causing conditions of stable weather for several consecutive days.
He strong thermal drop will cause widespread frosts to occur over the Pampas region, the Cuyo area and part of the center of the countryso the thermal contrast will be very marked between the beginning of the week and the end of it.
Orange alert from the National Meteorological Service for snowfall
They have been registering for several days significant snowfalls in the mountain area of Patagonia, so the situation is critical in many sectors. Among other data, we can highlight the registered at the base of Cerro Catedral, where more than 1.40 m of snow accumulated in the last hours.

With these characteristics, The most compromised area continues to be the Buenos Aires coast and the east and southeast of Uruguaywhich will present strong winds, with speeds that can reach up to 60 km/h with gusts of up to 75 km/h.
