Atacama Storms Dump 40 mm of Rain, Forcing ALMA Into Survival Mode

3 articles · Updated · IFLScience · Aug 28

Summary

  • NASA Landsat images from Aug. 6 and Aug. 14 show snow blanketing Chile’s Atacama Desert after winter storms transformed one of Earth’s driest regions.
  • Nearly 40 millimeters of rain fell in Taltal over three August days—about 10 times its annual average—as an unusually large low-pressure system and cutoff low tapped coastal moisture during El Niño.
  • ALMA suspended operations and moved its antennas into protective survival mode as snow and high winds hit the Chajnantor plateau; some other observatories in northern Chile also halted work.
  • SENAPRED said the August storms left 1,166 people in shelters, 580 homeless and one person dead, after flash floods and mudflows swept through places including Tocopilla.
  • Chile has faced storm damage since mid-July, with 15 deaths in Coquimbo earlier in the season, underscoring how the current Super El Niño is amplifying extreme weather.

Insights

As deadly floods ravage the hyper-arid Atacama, will this catastrophic deluge unexpectedly awaken dormant ecosystems in the barren wasteland?
Could the unprecedented snow in Earth's driest desert signal a permanent global climate shift rather than just a rare El Niño anomaly?
