A National Weather Service heat advisory for inland valleys across Southern California is set to take effect at 10 a.m. Saturday and extend until 7 p.m. Monday.
Forecasters said temperatures along the coast in San Diego would be in the upper 80s Saturday and lower 90s Sunday and Monday. Temperatures in the inland areas are expected to soar into the low 100s.
San Diego Gas & Electric said it has adequate power supplies lined up to meet customer demand during the heat wave, with crews on standby if needed. The utility recommends setting air-conditioners at 78 degrees and turning off unneeded appliances and equipment.
SDG&E and the San Diego County News Center offered the following tips for staying cool:
- Close blinds and curtains during the warmest hours of the day
- Wear light, loose-fitting clothing
- Drink plenty of water and avoid alcohol and sugary drinks
- Stay in an air-conditioned area during the hottest part of the day
- Take cool showers
- Avoid unnecessary hard work or activities outside during the hottest part of the day
