World’s driest desert floods as extreme weather events rise

Rains high up in the Andes mountains have led to torrents of water pouring into the Atacama desert below, sweeping away houses and roads. Meanwhile in the south, blistering temperatures have fuelled forest fires, leading the government to declare some regions a disaster area.

President Sebastian Piñera declared a “zone of emergency” in northern Chile on Friday after heavy rains devastated the country’s El Loa province. Flooding caused six deaths and destroyed nearly 100 homes, the National Emergency Office said Saturday. Alerts for heavy precipitation were in effect in Arica, Parinacota and Tarapaca.

The disasters are part of a pattern of increasingly extreme weather in the country that stretches for 4 270 kilometers (2 650 miles) along South America’s south-west coast. The capital, Santiago, hasn’t received its average annual rainfall in a decade, while temperatures in the city beat the previous record by a whole degree Celsius last month. It was the third time in three years the city has set a record high.

“Chile needs to be thinking about how to adapt to climate change, as it has such an isolated climate that makes it more vulnerable to droughts,” said Park Williams, a hydroclimatologist at Columbia University in New York. “For the last several decades, temperatures have risen and precipitation has declined in central Chile, making it more susceptible to wildfires.”

In the south, more than 600 forest fires are raging through 9 500 hectares (23 475 acres) of land, an increase in burnt areas from the year before. Compounding the problem are dense plantations of pine and eucalyptus for the forestry industry.

In the north, in addition to the fatalities, 37 000 people in the town of Calama were left without tap water for four days. More than a hundred homes sustained major damage in the nearby tourist resort of San Pedro de Atacama.

The storms have also affected state-owned copper miner Codelco and Freeport McMoran, which operate mines near Calama. Operations at some facilities were slowly resuming on Saturday. After returning from a trip to see the fire damage in the south, Pinera traveled north to see the floods. Strong to moderate thunderstorms are expected to continue through Sunday, according to Chile’s weather service Meteochile.
