SAN FRANCISCO (KRON) – A statewide Power Alert will be in effect Monday, June 12, California ISO – the manager of California’s power grid – announced Sunday.

“With electric transmission lines from Oregon still unreliable due to the explosive Bootleg Fire and continued high temperatures across the West resulting in increased demand for electricity, the California Independent System Operator (ISO) issued a statewide Flex Alert for Monday, July 12 to help stabilize the state’s electric grid and deal with uncertainty created by the extraordinary conditions.”

The Power Alert encourages consumers to:

  • Set thermostats to 78 degrees or higher
  • Avoid using major appliances, like dish washers, washers and dryers
  • Turn off all unnecessary lights
  • Use fans for cooling and unplug unused electrical items

Toasty temperatures prompted the Bay Area National Weather Service to issue an excessive heat warning and heat advisory for most of the Bay except the immediate East Bay Shoreline, the Coast and San Francisco.

Both weather alerts were in effect until Sunday at 11 p.m.

NWS excessive heat

Today, some areas will pop 100+, and the Bay will see 70’s take over for good coverage.

For the work week, a new weather pattern will drive cooling systems from the Northwest.

Temps will slide all week and settle by Friday. There doesn’t appear another pop by the weekend, but a few 90’s well Inland will remain by next weekend.

The National Weather Service urges people to stay safe by keeping cool and hydrated.

Bay Area counties have opened up cooling centers where residents can get relief from the heat in air conditioned spaces.

People who are staying home can keep their curtains drawn to keep the hot sunlight from raising indoor temperatures and utilize fans and cold water.
