South America’s cold snap eases and Agatha moves towards Florida

Exceptionally chilly circumstances endured throughout South America earlier this week. The circumstances had been alarming on the northern extent with unseasonably low temperature anomalies recorded as far north because the Tropics.

The depth of the chilly introduced uncommon Could frosts to low ranges throughout elements of Uruguay and Chile. On 31 Could in Santiago, Chile, temperatures fell to -2.1C, the bottom Could temperature recorded since 1969, and whereas that is exceptionally chilly for the time of 12 months, many periphery areas outdoors the primary metropolitan metropolis would have been a number of levels colder. The chilly wave was current throughout South America for nearly every week however is steadily coming to an finish via this weekend with hotter circumstances returning. Nevertheless, this occasion has marked the primary shot of polar air for the beginning of the southern hemisphere winter season.
