Buenos Aires Herald 
If your plans for Wednesday involve moving around the city, you might want to reschedule.
A cyclogenesis — a kind of low pressure area that develops into a cyclone — is set to hit central Argentina. While the epicenter will be in Córdoba province, it will also affect southern Santa Fe, Entre Ríos, and parts of northeastern La Pampa.
The National Weather Service (SMN, for its Spanish initials) has issued an orange weather alert for Buenos Aires City and large parts of BA province. This means the storm is expected to be “dangerous for society and life.”
According to the SMN, strong winds and heavy rainstorms are expected throughout Wednesday across Greater Buenos Aires. Affected areas could see between 70 and 120 mm of rain, with winds of up to 80 km/h.
There may be electrical storms, hail, and flooding, so the SMN is recommending that the population avoid open-air activities.
After a suffocating Monday and Tuesday that saw temperatures as high as 32°C, thermometers are expected to cool off in the coming days. The SMN forecasts temperatures ranging between 18-24°C for Wednesday and 16-20°C for Thursday. The cooler weather is expected to continue Friday. Temperatures will slowly pick up over the weekend.
Northern Argentina will continue to experience scorching heat, with temperatures as high as 38°C in parts of Chaco and Santiago del Estero. The western part of the country has been issued a code orange for winds: parts of Catamarca, La Rioja, and San Juan can experience gusts of up to 80 km/h, with a potential loss in visibility because of dust whipped up by the region’s infamous zonda wind.
Buenos Aires suffered a cyclone in August. At the time, SMN Spokesperson Cindy Fernández explained that this meterological process is known as “cyclogenesis.”
“During cyclogenesis, pressure plummets, and the atmosphere has to adjust to the new pressure, so air moves and produces wind,” she said. “This also causes persistent rain,
which, combined with wind, can make soil go softer, potentially making trees fall.”
“All of this to say, take precautions.”
