Long awaited rain returned to central Chile, including Santiago on July 12 and 13; however, dry weather quickly returned and there has been no additional rainfall since that storm system departed.
The storm system was the first in nearly two years to bring more than 25 mm (1 inch) of rain to Santiago, as generally there was 25-38 mm (1.00-1.50 inches) reported across the city.
After an extended dry stretch, rain will finally return to Santiago early next week as a potent storm system brings a soaking rain to south-central Chile.
While Santiago will likely receive at least some rainfall from this storm system, the most significant rain will remain to the south. Areas that will likely receive more than 25 mm (1.00 inch) include Curico, Chillán, Concepcion and Temuco. Localized rainfall amounts can exceed 75 mm (3.00 inches).
In Santiago, rainfall will likely be 12 mm (0.50 of an inch) or less, but any rainfall will be beneficial as the entire region remains locked in a drought has ongoing for several years.
Even though this storm may not bring significant rainfall to Santiago and areas farther north, the pattern will be continue to be more favorable for additional rainfall during the month of August.
Along with beneficial rain, significant mountain snow will be measured in meters from near and south of Santiago to east of Puerto Montt.
El Nino will have longer lasting impacts on the weather across Chile through at least October. More information about the long-range forecast for Chile and South America can be found here.
