When the National Weather Service (San Diego) issues a red flag warning, the weather conditions set the stage for a wildfire to grow and spread rapidly. This is normally caused by "Santa Ana" or "East" winds that blow dry and usually warm air from the north east.
When a red flag warning has been issued:
Please be careful not to spark a fire! The dry weather, dry grass and brush and strong winds can make a wildfire extremely hard to contain.
- No outdoor wood-burning fires
- Don't mow or trim dry grass when windy
- Never pull your vehicle over in dry grass
- Report any suspicious activities to prevent arson. See something - say something!
Please make sure you and your family are prepared!
- Register mobile phones for reverse 911 at: ReadySanDiego.com
- Make sure you are prepared to evacuate if notified to do so
- Make sure you have at least a half tank of gas in your car
- Make sure you are prepared to transport pets
- Make sure your family has a point of contact or meeting place
- Download and use the SD Emergency mobile app
During Red Flag Warning wind events SDG&E may de-energize power lines during windy conditions in some areas. This action is called a Public Safety Power Shutoff (PSPS) and it is done to prevent power equipment from sparking a wildfire. SDG&E normally notifies all customers they live in an area that may be subject to a PSPS and when the power is shut off. Make sure your contact information is updated with SDG&E to ensure that you receive their notifications!
SDG&E maintains a map of communities at risk for power shut offs and a map of known power outages.
