The warning describes "dangerously hot conditions with temperatures of 95 to 110 expected" and notes that heat-related illnesses increase significantly during extreme heat events.

Air quality alert for ozone
NWS Los Angeles/Oxnard relayed a South Coast AQMD air quality alert, issued July 30 at 4:02 p.m. PDT and running until 8 p.m. Sunday, for harmful levels of ozone (smog) pollution. The Western San Fernando Valley is among the listed areas. Per the alert, the highest ozone levels typically occur in the afternoon and early-evening hours, and levels vary by time and location. Sensitive groups — people with lung disease, older adults, people who are pregnant, children, and those who spend a lot of time outdoors — are identified as at greater risk. AQMD guidance in the alert includes limiting extended or intense outdoor activity when the AQI is in the orange range, keeping windows and doors closed, running air conditioning or an air purifier rather than whole-house fans or swamp coolers, and delaying use of gasoline-powered lawn equipment until evening hours. Current and forecast levels are posted at aqmd.gov/alertinfo.
