LOS ANGELES — On the eve of what's expected to be California's longest and most intense heat wave of the year, state electrical grid operators are warning residents to prepare for Flex Alerts and other emergency measures.
The heat wave — a result of a large dome of hot air sitting over Central and Southern California — is expected to begin Wednesday and last through Tuesday next week.
Record-breaking heat is possible Wednesday, Thursday, Sunday and Monday, according to the National Weather Service office in Oxnard.
