Heatwave Sweeps Across Western US, Excessive Heat Warnings Continue

Excessive heat warnings and advisories have been extended through the holiday weekend in Southern California, as temperatures are forecasted to reach exceptionally high levels. The warnings cover various regions, including the Antelope and Santa Clarita valleys, as well as parts of San Luis Obispo County. Health officials are urging residents to take precautions against heat-related illnesses, such as staying hydrated and seeking air-conditioned spaces. Free cooling centers are available for those without air conditioning. Nighttime temperatures will provide some relief in most valleys, but mountain areas will remain hot. Officials also warn of an elevated risk of fires due to the excessive heat.
