The peak of the heat wave is expected Thursday and Friday, the National Weather Service said. While it’s brought hotter 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.

A widespread heat wave is expected to intensify fire concerns across California as temperatures rise and landscapes further dry out. The Gifford, Rosa and Gold fires are burning.
