According to the Dirección Meteorológica de Chile (DMC), no region of Chile will escape the rain this week as a series of widespread precipitation events moves across the country from Arica to Magallanes. While this scale of nationwide rainfall is unusual, officials note it aligns with the winter season and is intensified by the El Niño phenomenon. Authorities have placed their primary focus on the northern territories, where heavy downpours and thunderstorms are expected to create hazardous conditions for residents.
Northern Chile Faces Severe Storms and High Zero Isotherm
The heaviest immediate concerns center on the northern regions of Atacama and Coquimbo. Between Tuesday, June 11, and Wednesday, June 12, the DMC forecasts thunderstorms and intense rainfall coupled with a high zero isotherm across these areas. According to authorities, these specific atmospheric conditions could trigger natural disasters that pose significant risks to the local population. In response, emergency monitors are urging residents throughout the north to stay vigilant for incoming weather alerts.
Specific northern impacts vary by location. In the Arica y Parinacota Region, Visviri and Putre face showers and sleet with winds ranging from 25 to 60 km/h between Tuesday and Wednesday, while Arica expects light drizzle and a sandstorm with winds of 40 to 60 km/h. Further south, Antofagasta anticipates rain, sleet, thunderstorms, and intense winds reaching up to 80 km/h in Ollagüe, Calama, San Pedro, Antofagasta, and Taltal, with dust storms in Tocopilla and drizzle in Mejillones. Atacama rounds out the northern threat with showers, thunderstorms, and winds between 25 and 40 km/h across El Salvador, Chañaral, Caldera, Copiapó, Huasco, Freirina, and Vallenar. Coquimbo will experience showers and thunderstorms in Vicuña, alongside isolated showers in Combarbalá, Illapel, and Los Vilos from Wednesday through Saturday.
Did You Know? While nationwide rainfall from Arica to Magallanes is an unusual occurrence, the current weather pattern is tied directly to the winter season and amplified by the active presence of the El Niño phenomenon.
Central Regions Prepare for Days of Intermittent Showers
Central Chile will experience a sustained period of wet weather running from Thursday, June 13, through Saturday, June 15. The Valparaíso Region and the Metropolitana Region—including Santiago’s various sectors, Colina, Curacaví, Melipilla, and San José de Maipo—will see intermittent showers and isolated rainfall throughout this multi-day stretch. Similar conditions are forecasted for the O’Higgins, Maule, and Ñuble regions, where coastal spots like Pichilemu and Constitución will also contend with winds reaching up to 40 km/h.
In O’Higgins, locations such as Rancagua, Rengo, San Fernando, and Santa Cruz face light, isolated showers. Moving down the map, Maule centers like Curicó, Molina, Talca, Linares, Cauquenes, and Parral will experience steady precipitation. Meanwhile, Ñuble cities including Cobquecura, San Carlos, and Chillán will combine isolated showers with moderate wind speeds.
Southern Sectors Monitor Rising River Levels
Southern regions from Biobío down to Los Ríos face additional hazards beyond standard rainfall. Authorities have warned that these southern sectors could experience significant increases in river flows, prompting a direct call for residents to monitor official alerts closely. In the Biobío Region, cities such as Concepción, Talcahuano, Lota, Lebu, and Los Ángeles will receive showers accompanied by winds of 25 to 40 km/h from Thursday to Saturday.
