Photos: Brutal heat wave bears down on Southern California

Labor Day will be sweltering, with hot conditions continuing through Wednesday or Thursday.

Highs between 105 and 110 degrees are expected across broad swaths of the San Fernando, San Gabriel and Santa Clarita valleys, as well as communities in lower mountain elevations, said Joe Sirard, a meteorologist at the National Weather Service’s Oxnard office.

The weather service is forecasting heat advisories and excessive heat warnings through Tuesday and is warning against heat illness.
