BREAKING: Buenos Aires, Argentina 🇦🇷 falls into darkness as intense heat pushes infrastructure beyond limits.
This is one of the hottest temperatures in recorded history for the city. Unfortunately, this is only the beginning of a brutal & historic heatwave in South America.
We have not observed above +40°C in Buenos Aires since 1995. This is the hottest day since 1957, so if you were born after that, this is the hottest day of your life so far (records go back to 1905).
A top-end storm is explosively deepening in the open Atlantic right now. Central pressure should drop below 930 hPa.
The jet stream dynamics are jaw-dropping.
The storm development is linked back to a baroclinic zone over the Southern States. Cold air flooded the USA with strong thermal contrast (very warm to the south).
A beautiful but powerful storm.
The jet stream interacting with the developing surface cyclone is crucial for such a powerful storm.
The coincidence of the surface cyclone under the 'right entrance' then 'left exit' greatly enhances the cyclone development
