Hurricane Hilary is bringing potentially "Catastrophic and life-threatening flooding" to California Sunday, prompting unprecedented tropical storm warnings for Los Angeles and San Diego, according to the National Hurricane Center.
Threat level: Veteran National Weather Service meteorologist David Roth wrote that the potential for a plume of 5 to 10 inches or more of rainfall to extend from inland areas of San Diego County northeastward into Nevada is equivalent to a Western version of Hurricanes Harvey or Florence.
