An interaction with an area of low pressure systems across Argentina during the July 6, July 7 and 8 of 2007, and the entry of a massive polar cold snap made as a result the worst winter of Argentina in almost forty years, where severe snowfalls and blizzards affected the country[1] The cold snap advanced from the south towards the central zone of the country during Friday, July 6, continuing its displacement towards the north during Saturday, July 7 and Sunday, July 8. On Monday July 9, the simultaneous presence of very cold air, above the average levels of the atmosphere as in the surface, gave place to the occurrence of snowfalls even in localities where snow is very slightly frequent. This phenomenon left at least 23 people dead.[2][3]

It was the third time that a phenomenon like this happened in the country. The first time was in 1912 and the second one was in 1918, occasion in which even there was major volume of snow.
