Tropical Storm Watch Issued for San Diego Coastal Areas

A Tropical Storm Watch has been issued for San Diego County Coastal Areas, effective immediately and expiring at 4:15 AM UTC on October 11, 2026. This alert, issued by the National Weather Service San Diego CA, indicates a potential for hazardous wind, significant coastal flooding, and major flooding from heavy rain.

Residents in Oceanside, Carlsbad, Chula Vista, and San Diego should prepare for potential winds of 39 to 57 mph. Efforts to protect property, including securing lightweight objects, should be underway now. Hazardous driving conditions, scattered power outages, and damage to structures like porches and sheds are possible. Complete preparations before winds become hazardous.

While true storm surge is not expected, significant coastal flooding and beach erosion are possible due to high tides near 7.5 feet, high surf, and increased onshore winds. Avoid beaches, and take necessary actions to protect flood-prone property. Dangerous swimming conditions and strong rip currents are anticipated.

A Flood Watch is in effect, with an additional 1 inch of rain forecasted. This poses a potential for major flooding, which may prompt evacuations and rescues. Rivers and small streams could overflow, and mountain areas face increased susceptibility to rockslides and mudslides. Heed all flood watches and warnings immediately.
