Despite being scary, the phenomenon in question can be plausibly explained. And no, it's not a woman actually screaming!
As clarified by the Portuguese Institute of the Sea and Atmosphere, when there is preservation of the passage of the wind, such as when facing with a window or any other obstruction that causes blockage, wind enters gaps and can result in a sound similar to a whistle.
As an illustration of this phenomenon, the Institute offers the example of a whistle, explaining that the sound produced does not originate from the expiration of air, but rather from the force exerted by the air when trying to dissipate.
According to information from the Civil Defense of Santa Catarina, the winds that have been plaguing the state in recent days can reach speeds of over 60 km/h.
In addition, the coast of Santa Catarina experiences a generalized maritime inspiration, with waves directed to the south and reaching heights of 1.5 to 2 meters, with peaks of 2.5 meters.
