Dangerously High Temperatures and Poor Air Quality Expected Through Monday

LOS ANGELES — Issued by the National Weather Service at 8:04 PM PDT on September 6, 2024.

Excessive Heat Warning: Temperatures Soar to 115°F Across Southern California

The National Weather Service (NWS) in Los Angeles/Oxnard has issued an Excessive Heat Warning for much of southwest California, including Los Angeles, Santa Clarita Valley, Ventura County, and surrounding areas. The warning remains in effect until 8 PM PDT on Monday. Temperatures are expected to reach up to 115°F, with overnight lows remaining in the 70s to lower 80s, offering little respite from the extreme heat.

High Risk for Heat-Related Illnesses

Residents are urged to take precautions against the severe heat, which poses a high risk of heat-related illnesses, particularly for the very young, the elderly, those without access to air conditioning, and individuals engaging in outdoor activities. To mitigate these risks, people should drink plenty of fluids, stay indoors in air-conditioned environments, and avoid outdoor activities during peak heat hours. Checking on vulnerable family members and neighbors is also highly recommended.

Air Quality Alert: Elevated Ozone Levels Pose Respiratory Risks

In addition to the heat, the South Coast Air Quality Management District has issued an Air Quality Alert for the same regions, including Santa Clarita Valley, San Fernando Valley, Los Angeles County Inland Coast, and the San Gabriel Valley. This alert remains in effect until 8 PM PDT on Monday due to elevated levels of ozone, a predominant summertime pollutant that can cause significant respiratory health issues.

Health Risks from Poor Air Quality

High ozone levels, which are expected during the afternoons and early evenings, can exacerbate respiratory conditions such as asthma and COPD, particularly in children, older adults, and those with preexisting health conditions. Residents are advised to limit outdoor activities, especially during times of poor air quality, and take steps to reduce ozone formation, such as delaying the use of gasoline-powered equipment and conserving electricity.

Precautionary Measures and Health Tips

• Stay Indoors: Limit exposure to outdoor heat and poor air quality by staying indoors as much as possible.
• Hydrate Frequently: Drink plenty of water to stay hydrated in extreme heat.
• Conserve Energy: Set air conditioners to a higher temperature and reduce the use of large appliances.
• Check Air Quality: Monitor current air quality levels through the South Coast Air Quality Management District website or their mobile app for updated alerts and health advisories.
