A new frontal system will bring light rain and strong winds to Santiago and central Chile on Thursday, July 21 [1, 2].
This weather pattern is significant because it follows a period of instability and threatens infrastructure and public safety through high-velocity wind gusts. The system affects multiple regions, including Biobío and Ñuble, extending the reach of the storm across the central zone [2, 3].
Arlette Chacón, a meteorologist with TVN, said that while the precipitation on Thursday is expected to be light, the primary concern is the intensity of the wind [1, 2]. The frontal system is creating conditions for severe gusts, with some reports indicating wind speeds could reach 100 km/h in certain areas [4].
Local authorities have already taken preventative measures to protect residents and students. School classes have been suspended across nine regions to mitigate risks associated with the storm [5]. Santiago is expected to be a point of maximum intensity for the system, which combines rain and wind to create hazardous conditions for commuters, and residents [3].
Weather officials are monitoring the movement of the system to determine when the rains will fully subside. While the current rainfall is described as light, the combination of moisture and high wind speeds increases the likelihood of fallen trees, and power outages in the affected regions [1, 2].
“Wind speeds could reach 100 km/h in certain areas”
The suspension of classes in nine regions indicates that the Chilean government views the wind speeds as a significant public safety risk rather than a routine weather event. By prioritizing wind hazards over the light nature of the rain, authorities are attempting to prevent casualties and infrastructure damage common during high-velocity frontal systems in the central valley.
