More than 41 million Americans across California, southern Nevada and northwest Arizona are under flood watches on Wednesday amid a rare, high risk for excessive rainfall and flooding.
This includes major metros like Los Angeles, San Francisco, Sacramento, California, San Diego and Las Vegas.
A “High Risk for excessive rainfall” is in place for Los Angeles, including I-10 from San Bernardino to Santa Monica and areas north like Highway 101 to Thousand Oaks, I-5 to Burbank, Santa Clarita, and up to Pyramid Lake and all of I-210. Travel on these roads is not recommended as they may become flooded, officials said. Low-lying neighborhoods in these areas could also become flooded, forecasts show.
Being under a “High Risk” designation is rare. This risk is only issued about 4% of days, accounting for one-third of all flood-related fatalities and 80% of all flood-related damages, according to the NWS.
