The Los Angeles County Department of Public Health issued a warning Monday about the air quality in the Santa Clarita and San Gabriel valleys.
Children with asthma or other respiratory problems shouldn't do physical education or other activities outside, according to the public health department.
The South Coast Air Quality Management District said the air quality was unhealthy for everyone in the Santa Clarita Valley and for sensitive individuals in the San Gabriel mountains and valleys.
