Tropical Storm Watch Issued for San Diego Coastal Areas

A Tropical Storm Watch has been issued for San Diego County Coastal Areas, effective immediately as of October 9 at 1:57 PM PDT. This watch, issued by the National Weather Service (NWS) San Diego, includes Oceanside, Carlsbad, Chula Vista, and San Diego. Residents in these areas should finalize preparations for hazardous wind, potential significant coastal flooding, and widespread heavy rain.

The NWS forecasts peak winds of 10-15 mph with gusts up to 30 mph, but warns of a potential for sustained winds of 39 to 57 mph. Damage to outdoor property and scattered power outages are possible. Efforts to secure property should be underway now. Act to complete preparations before hazardous winds begin.

Significant coastal flooding and beach erosion are expected due to tides exceeding 7 feet, high surf, and increased onshore winds. Dangerous swimming conditions and strong rip currents are likely. Do not plan to visit the beach and take immediate action to protect flood-prone property. Monitor forecasts and follow instructions from local officials.

A Flood Watch is also in effect, with around 1 inch of rain anticipated. The NWS indicates potential for major flooding, which may necessitate evacuations and rescues. Emergency plans should account for major flooding. Heed any flood watches and warnings; failure to act could result in serious injury or loss of life.

This Tropical Storm Watch is effective until October 9 at 10:00 PM UTC. For more information, visit sdcountyemergency.com.
