The National Weather Service (NWS) is predicting a heat wave over southern California that will last through Friday. This is due to an upper air high pressure system located over Baja California. As of Tuesday afternoon, the NWS has issued a heat advisory for the Inland Empire area of San Bernardino and Riverside Counties and the Orange County inland areas, which is in effect from 10 am Tuesday until 9 pm on Friday.
When air quality is Unhealthy and reaches an air quality index (AQI) range of 151 to 200, everyone may begin to experience some adverse health effects, and residents with higher sensitivity to air pollution may experience more serious effects. When air quality is Very Unhealthy with an AQI range of 201 to 300, everyone in the region may experience more serious health effects.
Ozone air pollution can cause respiratory health problems, including trouble breathing, asthma attacks, and lung damage. Research also indicates that ozone exposure can increase the risk of premature death. Children, older adults, and people with asthma or COPD may be more sensitive to the health effects of ozone.
