A heat wave and a heat dome will build up pollution in Bay Area skies on Wednesday in a significant way.
That means ground-level concentrations of ozone are expected to be in the unhealthy range, especially for seniors and young children, with hazy skies dominating the scene in the East Bay. On Wednesday afternoon, the Bay Area Air Quality Management District warns against strenuous exercise. Polluted air is shortening human lifespans more than smoking tobacco, according to a new study from the University of Chicago.
This could be the first PSPS event of the year, and the first one in two years.
PG&E may be forced to preemptively cut off power to a total of 8,000 customers starting 3 a.m. Wednesday primarily east of the Mendocino National Forest through Redding and north of Lake Oroville. Very few shutoffs are in the Bay Area.
Current air quality around the three college campuses is moderate and still remains healthy. However, some isolated geographical locations are approaching unhealthy levels. The San Mateo County Community College District will monitor and notify the campus communities if the air quality index exceeds 100.
