SoCal sees two ‘thousand-year’ storms within weeks. More could be coming
LA TimesWeather officials had been warning Californians about the wrath of El Niño for months — even as some residents had begun to think the typically soaking climate pattern had gone AWOL. “The idea that climate change is causing the wet and dry periods to become more extreme for California — that’s what the models have been predicting, and that’s what’s been happening,” Ralph said. “In winter, we’ll see these big storm systems that are moving in from the northern Pacific … but by the time they get to Southern California, a lot of that moisture is gone,” Adams said, pointing to last winter’s epic stream of atmospheric rivers that pounded the North and Central Coast. An “impactful atmospheric river event” is expected to move south along the West Coast from Jan. 31 to Feb. 5, bringing heavy rain, significant snow and high winds, said Brad Pugh, a meteorologist at the National Weather Service’s Climate Prediction Center. “California and the southwest U.S. has far more variable annual precipitation than anywhere else in the country, and these atmospheric river storms are the primary storm type that determines whether it’s going to be wet or dry,” Ralph said.
