Air quality remained at unhealthy levels in the early afternoon Friday.
The Air Quality Index for a Hollister station on Fairview Road measured at 117 as of shortly before 1 p.m., according to the Monterey Bay Air Resources District.
The AQI measures pollutants, or particles, in the air. Measurements between 100-150 are considered unhealthy for sensitive groups, members of which should avoid prolonged activities outdoors. Measurements from 150-200 are considered unhealthy overall.
Air quality in the region has been poor over the past week due to the Camp Fire in Butte County. Schools have responded in a variety of ways, with Gavilan College cancelling classes Thursday and Friday (the AQI in Gilroy was 188 in the early afternoon Friday) and some outdoor activities cancelled at local schools.
Air quality still poor Friday afternoon
