The NWS has also issued a red flag warning for critical fire danger in areas like the San Gabriel Mountains and parts of northern Los Angeles County, where temperatures could reach up to 108°F (42.2°C) with humidity levels dropping below 10%. Additionally, Southern California Edison has warned of potential Public Safety Power Shutoffs affecting approximately 3,100 customers to mitigate wildfire risks.
