Summary

  • Flooding rain, 40-plus-mph wind gusts and possible coastal flooding are expected across Southern California and the Desert Southwest through Monday or Tuesday as Rachel’s remnants move inland.
  • Rain totals of 1 to 5 inches, with locally higher amounts, could trigger flash flooding in dry creeks, slot canyons and urban areas including the L.A. Basin, San Diego, Las Vegas and Salt Lake City.
  • Southern California beaches could see erosion and damage to roads and structures Sunday, while strong winds in mountain and higher-elevation areas of Arizona, Nevada and Utah may cause tree damage, blowing dust and power outages.
  • More than a foot of snow is possible in parts of Wyoming, Montana and Idaho as Rachel’s moisture meets a cold front, which will also drop temperatures 5 to 15 degrees below average across much of the Southwest by Monday.
  • At the same time, Category 4 Hurricane Simon is forecast to hit Mexico’s Jalisco state Sunday, with up to 30 inches of rain and dangerous storm surge threatening Puerto Vallarta and nearby coastal areas.
