Heat Advisory Extended - High Temperatures Forecast for Parts of Los Angeles County

The Los Angeles County Department of Public Health urges residents to take precautions to avoid heat-related illness - such as heat exhaustion, heat stroke, and heat cramps - as high temperatures are forecast to impact the region next week.

The National Weather Service (NWS) has issued a Heat Advisory as high temperatures have been forecasted for the following areas:

Heat Advisory

Issued when hot weather is expected to cause discomfort and may lead to heat-related illness for some people, especially those who are vulnerable to heat, as indicated below.

Public Health recommends the following tips to keep yourself and others safe during excessive heat:

If you don’t have air conditioning, follow these tips:

Heat-Related Illness

It’s important to know how to recognize and help someone who is experiencing a heat-related illness. Call 911 right away if you see these symptoms: high body temperature (103°F or higher), dizziness, nausea, passing out, headache, fast &strong pulse, confusion, and hot, red, dry, or damp skin.

Watch out for each other. Everyone should take precautions to prevent heat-related illness, but there are groups more vulnerable to heat. Check on those who are sick or have chronic conditions, older adults, pregnant people, children, those who live alone, pets, and outdoor workers and athletes.

“Heat causes more deaths in the U.S. annually than floods, storms, and lightning combined. Those most likely to get ill during the heat include older adults, young children, outdoor workers, athletes, and individuals with chronic medical conditions,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “Remember, your safety and the safety of others is crucial during extreme heat conditions. If you or someone around you experiences symptoms of heat stroke or heat exhaustion, such as dizziness, nausea, rapid heartbeat, confusion, or passing out, seek medical help immediately.”

Local Impact

To check the risk of heat-related impacts for your specific city, go to the NWS HeatRisk website and click on Location Search and enter your city or use the zoom (+) button in the top left corner to see nearby cities more clearly. For actions to take based on your city’s HeatRisk category, read the NWS’ Understand HeatRisk guide.

The NWS HeatRisk takes into consideration:

* HeatRisk is a comprehensive calculation used by NWS that combines current weather forecast data, historical climate data that is specific to each geographic area, and social vulnerability data (i.e., CDC Social Vulnerability Index) to inform level of heat risk specific in each geographic area in a much more detailed and accurate way than a single temperature reading.

County and City partners have planned ways to safely operate cooling centers during times of high heat. Residents who do not have access to air conditioning are encouraged to take advantage of these free cooling centers, splash pads, and community pools. To find a location near you, visit https://ready.lacounty.gov/heat/ or call 211.

Los Angeles County residents and business owners, including people with disabilities and others with access and functional needs can call 211 for emergency preparedness information and other referral services. The toll-free 211 number is available 24 hours a day, seven days a week. 211 LA County services can also be accessed by visiting 211la.org.
