As a result of the excruciating heat in Buenos Aires, last week, the National Meteorology Service (SMN) released a yellow alert that was soon pumped up to the dreaded orange shortly after. Things seem to be getting worse, after four consecutive days of unbearable heat Buenos Aires has been moved up to a “red heat alert,” which will stay in town until Friday, according to reports.

If the mortality risk was high before, now it’s officially extreme. Not only are the commonly at-risk groups particularly vulnerable, but warnings have also been issued for younger people with the Government suggesting everyone stay home, cool and hydrated.

Even though the forecast predicts clouds with a chance of rain and storms for the rest of the week, the SMN warned temperatures are expected to remain high, with maximums between 31°C and 34°C on Wednesday and Thursday. Relief probably won’t arrive until Friday, when the temperatures are expected to be as low as 18°C and as high as 26°C.

But why exactly is the weather so tropical-ish anyway? Is it the global warming? Are Argentines paying off some kind of punishment? Does it have anything to do with the solar eclipse?

According to Pablo Canziani, doctor in Physics and an investigator from the National Scientific and Technical Research Council (CONICET), the extreme heat is due a phenomenon that’s common towards the end of the summer where a blockade of hot air settles on this part of the world.

So what’s the deal? The system of low and high pressure of the Southern Cone interacts in a way that brings hot humid air from Brazilian to Argentina for several days: “a normal blockade lasts between 5 and 11 days, and it’s hard to say when it’s going to break.”

Now you know. Watch Netflix, go to the movies, crash at your friend-with-a-pool’s house and hunker down. It’s going to be a hot one.
