While Post-Tropical Storm Rachel made landfall away from San Diego, local officials have reactivated some safety protocols and advised residents to avoid beach areas on Sunday.

“A coastal flood warning is active until Sunday, Oct. 11, at 3 p.m,” the city posted on its X account on Sunday. “Significant coastal flooding and erosion are likely. A strong swell is also impacting the coast. People are encouraged to avoid the beaches, especially during high tides.”

The storm made landfall in Baja California Norte in Mexico late Saturday night. According to the National Weather Service (NWS), however, Rachel’s remnants “will bring periods of moderate to heavy rain to all of San Diego County” through late Sunday afternoon. The agency said a flood watch remains in effect until 8 p.m on Sunday.

In response, city officials also reactivated the Inclement Weather Shelter Program to help unhoused residents on Sunday avoid the storm at the following locations:

  •  Father Joe’s Villages Joan Kroc Center, 1501 Imperial Ave.: Spaces for up to 61 adult individuals plus 11 beds for families with minor children and/or single women. Check-in begins at 4 p.m. and lasts until capacity has been reached. Check-out is at 5 a.m.
  • Living Water Church of the Nazarene, 1550 Market St.: Spaces for up to 28 adults, with the reservation process open from 1-4 p.m. Check-in begins at 8 p.m. for people with reservations. Check-out is at 6:30 a.m.

While the coastal warning remained active, the NWS on Sunday cancelled a flood advisory for the San Diego River at Fashion Valley in an alert of its own.

“The river is expected to rise to a crest of 6.8 feet this afternoon which is below action stage,” the agency said.

The agency did, however, issue a wind advisory for the San Diego County mountain area, including Julian and Pine Valley, through 5 a.m. on Monday, forecasting “southwest winds 25 to 35 mph with gusts up to 60 mph.”
