The Spin


Narrative A

El Niño's fingerprints are all over the deadly windstorm that tore through São Paulo and Rio de Janeiro. The gust front that hit hurricane-force speeds broke off from a storm system fueled by El Niño in southern Brazil. Winter gust fronts are rare precisely because they need unusual moisture to form, and El Niño is delivering exactly that.

Narrative B

Pinning this windstorm on El Niño overstates the science and distracts from straightforward meteorological explanations. The gust front was driven by cold-front activity and meteorological troughs, a relatively common phenomenon that was more intense than usual.
