High temperatures are expected to continue Sunday as Southern California’s heat wave intensifies, according to the National Weather Service.

Forecasters say the weather system that has been building over Southern California is strengthening and will cause temperatures to keep climbing higher. Temperatures are predicted to be in the low to mid-80s at the beaches and in the 90s to 100s inland. Cooling centers have opened up throughout the Southland for those needing refuge from the heat.
