In anticipation for the upcoming heat, the National Weather Service has issued an Excessive Heat Warning. This applies to San Diego County inland valleys, mountains and the desert from Wednesday morning to Friday night. Added to the warning is also a Heat Advisory for the coastal and metro cities. This will go into effect on Thursday morning and last through Friday night as well.

SDG&E wants customers to plan ahead now, and take steps to cool down their homes. This heat wave is expected to bring warm temperatures into the evening hours. "Your electricity rate is different throughout different periods of the day. In the morning, it's different than a really expensive rate in the afternoon during 4:00-9:00, that's called peak pricing," said Anthony Wagner, Communications Manager for SDG&E.
