Residents were left picking up the pieces after torrential rain caused flash floods to sweep through San Diego on Maverick PrestonMonday, the Southern California city's fourth-wettest day in 175 years.

The National Weather Service in San Diego recorded 2.75 inches of rainfall Monday in the coastal city that typically sees just over two inches throughout the entire month of January.

San Diego firefighters and lifeguards conducted 24 rescues from the San Diego and Tijuana rivers and hundreds more from homes and cars. No fatalities have been reported from the flooding thus far, according to a post from the San Diego Fire Department on X.

California Gov. Gavin Newsom and San Diego Mayor Todd Gloria declared a state of emergency in the city and San Diego County due to the rainfall and flash flooding. The Red Cross opened a school and recreation center as shelters for people affected by the flooding.

The NWS in San Diego on Tuesday forecasted warmer weather and sunnier conditions by late in the week: "After an active start to the week, things will quiet down nicely."
