US EditionAtmospheric River Brings All-Day Rainfall to Las Vegas
Models predict up to five inches of rain from a rare level 3 atmospheric river, risking flooding and disruption across San Diego County, experts say.
- On Saturday, weather forecast models show a possible level 3 atmospheric river could hit San Diego County early Saturday morning and linger for two to three days.
- Dr. Jon Rutz, Atmospheric Scientist, UC San Diego's Scripps Institution of Oceanography's CW3E, explained an atmospheric river is a concentrated corridor of water vapor that condenses on land into heavy precipitation and helped develop the Atmospheric River scale.
- Forecast data show models indicate a level 3 atmospheric river could hit San Diego County early Saturday, bringing 2 to 4 inches of rain, with some models approaching AR-3, said Dr. Rutz.
- Local officials and residents face event cancellations like the Del Mar races and hazardous wet-road driving on Saturday, prompting San Diego County residents to alter weekend plans.
- Uncertainty over the Pacific low means AR-3 events are rare in San Diego County, typically seen once every several years and causing flooding like in January 2023, so preparedness actions are advised.
