| Area Affected | Expected Temperature |
|---|---|
| A portion of southwest California | Around 90 to 100 degrees |
Hot temperatures may cause heat illnesses, so it’s important to take precautions. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside, wear lightweight and loose-fitting clothing, and try to limit strenuous activities to early morning or evening.
If you see symptoms of heat exhaustion or heat stroke, take action immediately. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments.
Air Quality Alert
The South Coast Air Quality Management District has issued an Air Quality Alert due to elevated ozone air pollution until 7 PM PDT Tuesday, June 25, 2024.
| Area Affected | Potential Health Effects |
|---|---|
| South Coast Air Basin | Respiratory health problems, including trouble breathing, asthma attacks, and lung damage |
Elevated levels of ozone, the predominant summertime pollutant, are likely to result in poor air quality in the afternoon and early evening hours. Ozone air pollution can cause respiratory health problems, especially for children, older adults, and people with asthma or COPD.
To help minimize ozone air pollution levels, limit the use of gasoline-powered lawn and garden equipment until the evening hours, conserve electricity and set your air conditioner at a higher temperature, try to delay trips to the gas station and the use of household chemicals until the evening, and check air quality levels and take appropriate action as needed.
When air quality index (AQI) are Unhealthy for Sensitive Groups (orange), people with heart or lung disease, pregnant women, children, and older adults should limit prolonged or heavy outdoor exertion. When air quality reaches Unhealthy (red) AQI levels, everyone may experience adverse health effects and sensitive groups should avoid time outdoors. As Very Unhealthy (purple) AQI levels, sensitive groups should avoid all outdoor physical activity and everyone else should avoid prolonged or heavy outdoor exertion.
