"These are record-breaking temperatures," he said, "some of the hottest temperatures."

The thermometer hit 86 degrees in Oxnard, breaking the old record of 84 set in 2007. In Camarillo, the temperature reached 89, six degrees warmer than the previous high, also in 2007.
Seto warned that the heat could strain the power grid and outages were possible. It also could pose health risks for those active and outdoors.
