A Spare the Air Alert has been issued for Friday due to smog and unhealthy ozone layers in the Bay.

Temperatures are expected to exceed 100 degrees inland, while 90s are expected near the Bay and a range of 70s and 80s and even pockets of 90s right along the coastline.

According to the National Weather Service, an Excessive Heat Watch has been upgraded to an Excessive Heat Warning for the East and North Bays, effective Friday at noon through Wednesday at 7 p.m.

The heat continues into Saturday, but we’ll see some relief come Sunday to close out the weekend.

After a slight cooldown on Sunday, temperatures will once again warm up for the new week ahead, showing potential of temperatures climbing even further.

Due to the excessive heat, PG&E is warning customers to prepare for possible power outages in the coming days.

A Flex Alert has been issued for Friday night.

PG&E customers are strongly advised to conserve electricity during peak hours – between 3 p.m. and 10 p.m. – and to adjust thermostats to 78 degrees or higher.

The utility company said it does not anticipate public safety power shutoffs (PSPS) during this heat wave, but are preparing for possible shutoffs later this fire season.
