The air quality in the San Gabriel Valley on Monday has been rated as 'unhealthy for sensitive groups' on Monday by the South Coast Air Quality Management District.
At that level, AQMD advises that active children and adults, and
people with respiratory disease, such as asthma, should limit prolonged outdoor
exertion.
The San Gabriel Mountains also fall under the same designation for Monday.
Elsewhere in Southern California, including parts of San Bernardino and Riverside counties and the Santa Clarita Valley the air quality rating is 'unhealthy," which means sensitive groups should avoid outside exertion all together and even healthy groups should limit it.
