Did You Know? The hydrometric station tracking the Andalién River’s critical thresholds is situated at the location formerly known as the Chaimávida toll station in the Biobío region.
Emergency Protocols and Anticipated Evacuations
Authorities have mobilized resources and readied specialized response teams to address potential impacts on populated sectors and infrastructure. The mandated measures include preparing for possible evacuations, positioning heavy machinery, and setting up protective river defenses, according to institutional updates. Officials also instructed a reinforced monitoring routine for regional rivers and ravines, noting that sudden surges in water volume can trigger flash floods.
Maintaining strict adherence to official evacuation routes and avoiding swollen waterways remains critical during active red alert phases.
Special attention is directed toward precordilleran zones, where rain falling on accumulated snow can accelerate snowmelt and provoke rapid, hazardous increases in downstream flows. Senapred advises residents to stay clear of swollen channels, identify safe zones, and review established evacuation routes.
