Potential of ‘Life-Threatening Flooding’ from Hilary in SoCal Mountains, Deserts and Southwest Nevada

August 18, 2023

AccuWeather on Friday issued an alert warning of the potential of a “life-threatening, flooding disaster” in the mountains and deserts of Southern California and far southwest Nevada due to Hurricane Hilary.

In the area, primarily east of Palm Springs and north toward Death Valley, 4 to 8 inches of rain is expected, which can quickly cause washouts and mudslides, according to AccuWeather.

AccuWeather said the rain has to potential to “fall rapidly at times, putting significant strain on infrastructure including interstates and rail lines.” That infrastructure may be unable to handle the historic rain amounts, the weather service added.

“The impact from Hilary has the potential to be an extraordinary event, one that is rare and unprecedented,” AccuWeather Director of Forecasting Operations Dan DePodwin said in a statement. “In the interior of southern California, road closures due to washouts are likely. At the coast, coastal flooding can occur from Los Angeles to San Diego along with gusty winds that can cause power outages.”

According to AM Best, the top homeowners multiperil insurers in California include:

  • State Farm Group (20.6%)
  • Farmers Insurance Group (14.5%)
  • CSAA Insurance Group (6.7%)
  • Liberty Mutual Insurance Cos. (6.4%)
  • Allstate Insurance Group (6.3%)

AccuWeather meteorologists first warned on Thursday that Hurricane Hilary was anticipated to bring heavy rain, flash flooding and strong winds to parts of California, Nevada and Arizona.
