August 14, 2020 (San Diego) -- The California Independent System Operator (ISO), which oversees the statewide electric grid, has directed SDG&E to initiate rotating, one-hour service interruptions (rotating outages) throughout its service territory in San Diego and southern Orange counties. The blackouts are underway and are currently affecting thousands of residences.  View a list of current outages and estimated restoration times at  https://www.sdge.com/residential/customer-service/outage-center/outage-map.

While the rotating outages will be widespread in the region, communities located in high fire threat districts, which experience public safety power shutoffs, will be exempt from the service interruptions, SDG&E announced today.



The local outages are the result of excessive heat driving up electricity use and putting strain on the grid. CASIO has declared a “Stage 3” power emergency because contingency reserves have fallen or are anticipated to fall below requirements and cannot be restored without service interruptions.

June 30, 2020 (San Diego’s East County) – The weather will be warming up over the Fourth of July weekend. But before you head to the beach, be aware that elevated surf is forecast to generate strong rip currents that will be hazardous to swimmers this weekend and next week.

On Sunday and Monday,  breezy winds, warmer conditions and low relative humidity will create elevated fire weather conditions, says meteorologist Casey Oswant with the National Weather Service. The conditions are “favorable for fast-moving grass fires,” Oswant cautions.
