THE WATER

A frontal system coupled to a strong atmospheric river runs Sep 22 to 24, with an alerta for moderate-to-strong precipitation across Maule, Nuble, Biobio, La Araucania, Los Rios and Los Lagos: about 100 to 105 mm in 48 hours, 70 to 100 mm in the precordillera on Wednesday, and winds to 70 km/h. The compounding detail is the high freezing level, which puts rain where snow would normally fall and stacks snowmelt on top of runoff in Andean catchments; rain may reach Santiago midweek. The southern hemisphere's energy has moved from the Atlantic side of the continent to the Pacific side. Relayed through national desks.
