Meteorologist Iván Torres said that an atypical weather system will bring rain to Santiago and the central zone of Chile this week [1].
These forecasts are critical for the Metropolitan Region as the intensity of the precipitation is expected to exceed initial estimates, potentially impacting urban infrastructure and daily commutes.
Torres, a meteorologist for TVN and host of "Buenos Días a Todos," said that the rain is driven by a frontal system from the south that differs from typical patterns [1]. This system is transporting moisture into the region, which has resulted in a drop in temperatures and an increase in cloud cover [2].
"Será un sistema frontal que no es el típico que viene del sur, y traerá de vuelta las lluvias a Santiago," Torres said [1].
According to the updated forecast, the most intense rainfall is expected on Wednesday, May 6, 2026 [3]. Torres said that the volume of rain for that day will be higher than what was originally predicted by meteorological models [3].
"Las lluvias previstas para este miércoles 6 de mayo serán más intensas de lo estimado inicialmente," Torres said [3].
The weather shift is characterized by a combination of cooling and cloudiness that creates the ideal conditions for precipitation [2]. The forecast specifically targets the central region, with a primary focus on the city of Santiago, and the surrounding Metropolitan Region [2].
"Hay una baja en las temperaturas junto con nubosidad que favorece la precipitación," Torres said [2].
“"Las lluvias previstas para este miércoles 6 de mayo serán más intensas de lo estimado inicialmente"”
The arrival of an atypical frontal system suggests a deviation from standard seasonal weather patterns in central Chile. When precipitation exceeds initial estimates in a densely populated area like the Metropolitan Region, it increases the risk of flash flooding and transport disruptions, necessitating heightened readiness from local emergency services.
