Across southern areas of the state of California, 25 fatalities were attributed to a heat wave that prompted temperatures to soar past 40°C (104°F). The excessive heat resulted in the declaration of an 'electrical emergency' by energy officials during the week of September 2 and thus left about 55,000 people without electricity for two days (BBC News).
