A widespread extreme heat warning remains in place for much of Southern California through Saturday, warning of "dangerously hot conditions" causing a high risk for heat illnesses.

The peak of the heat wave is expected Thursday and Friday, the National Weather Service said. While it’s brought warmer temperatures than in recent weeks, it is not particularly extreme in terms of all-time Southern California highs. “This is definitely more normal heat for this time of year,” Sam Zuber, an NWS meteorologist said.

The peak of a heat wave lingering over Southern California is expected on Thursday, which could bring record-breaking temperatures to some areas.
