During the winter 2020, record-breaking temperatures of up to -23°C have been measured across the lower regions of Argentina and Chile. Powerful Antarctic cold fronts riding anomalously-far north stormtracks of deep cyclones have accompanied the freeze, and have delivered extremely high accumulations of snow (of 5+ feet / 150 cm+).
“This is an atypical winter with great snow storms. Since the nineties there was a tendency to lesser snow precipitation but this year climate conditions have even caused snow falls in certain areas of Patagonia, unaccustomed to such extremes”, according to weather experts /https://en.mercopress.com/2020/07/25/argentine-patagonia-provinces-under-a-blanket-of-snow/.
“None of the three countries, Argentina, Chile and Ecuador remember such a cold and snowy start to winter in the last decade.” Ski resorts in Andas had in July 7 metres (23 feet) of snow, but were closed cause COVID. /https://www.iceagenow.info/twenty-three-feet-of-snow-in-the-andes-but-ski-areas-closed-due-to-covid-19//.

Livestock farming was in a “critical state”. During second half of July 2020, the Rio Negro (770 MASL) government was forced to declared a State of Emergency and an Agricultural Disaster in 6 regions of Argentina, which means farmers in the western province are now “exempt from taxes for a short time”.
