Red alerts now cover Valdivia and Futrono, Arauco and Cautín, after the first storm left 161 homes affected in Los Ríos and about 30 families cut off in Lanco. A second frontal system with a category-3 atmospheric river is forecast from Coquimbo to Los Lagos, with more than 40 mm of rain and gusts near 80 km/h. (Handled with care.)

WHAT THEY'RE SAYING

One weather communicator described heavy rain from an atmospheric river bringing flooding and red alerts to south-central Chile. The report underscores how the incoming system is already producing widespread effects on the ground. Forecasters have been tracking the approach of a follow-on atmospheric river that is expected to expand the areas under alert.
