A storm track is expected to bring several days of rain to central-southern Chile this week [1, 2].
The arrival of this atmospheric system is significant for the region's water security and urban planning, as it may disrupt typical weather patterns for Santiago and Valparaíso.
Meteorologist Arlette Chacón said the system could produce rain across the center-south zone of the country [1]. The forecast specifically highlights Santiago and the Metropolitan Region as primary areas of impact, with the possibility that the weather system will extend toward Valparaíso [1, 2].
Data from the European Centre for Medium-Range Weather Forecasts, known as the ECMWF, indicates the presence of an atmospheric system that favors the generation of weak showers [2]. This specific model suggests that the storm track will create conditions conducive to light precipitation rather than severe storms.
Local authorities and residents in the Metropolitan Region are monitoring the development of the system throughout the week [1]. While the showers are expected to be light, the duration of the event, spanning several days, could lead to accumulated moisture in urban areas [1, 2].
The forecast remains subject to change as the system moves across the region. Meteorologists continue to analyze the ECMWF signals to determine if any surprises may occur during the current week [2].
“A storm track is expected to bring several days of rain to central-southern Chile this week.”
The reliance on the ECMWF model indicates that while a weather event is likely, the low intensity of the predicted showers suggests a low risk of flash flooding. However, the extended duration of the rain may provide a modest reprieve for regions facing dry conditions, provided the system maintains its projected track.
