Full Notification

The Los Angeles County Health Officer has extended a Heat Alert for the Los Angeles Basin Saturday, September 5 through Monday, September 7. Public Health reminds everyone to take precautions to avoid heat-related illnesses, especially older adults, young children, outdoor workers, athletes, and people with a chronic medical condition who are especially sensitive to adverse health impacts from extreme heat. Public Health offers the following recommendations during high-temperature days:

• Drink plenty of water and keep hydrated throughout the day.
• If you must go out, plan your day to avoid going out during the hottest hours and wear sunscreen. Wear lightweight, light-colored clothes, and bring a hat or umbrella with you.
• Cars get very hot. Never leave children or pets in vehicles and call 9-1-1  if you see a child or pet in a car alone.
• Beware of heat-related illness, like heat stroke, and call 9-1-1 if you see these symptoms: high body temperature, vomiting, and pale and clammy skin.
• Check on those at risk, like those who are sick, older adults, pregnant women, and children, and those who live alone.
• Avoid strenuous workouts wearing face coverings or masks not intended for athletic purposes.

In addition, a statewide Flex Alert will be in effect beginning Saturday and extending through Monday from 3:00 PM to 9:00 PM. The California Independent System Operator (CAISO) issues a Flex Alert when the electricity grid is under stress because of generation or transmission outages or from persistent hot temperatures. Consumers are urged to voluntarily conserve electricity to help avoid rotating outages.

Labor Day weekend temperatures are forecast 10-20 degrees above normal for California, and the power grid operator is predicting an increase in electricity demand, primarily from air conditioning use. Overnight temperatures statewide don’t allow infrastructure to cool down. With forecasts above average, consumers can take the stress off the grid by lowering energy use between the hours of 3:00 PM to 10:00 PM, when temperatures remain high, and the sun is setting, removing thousands of megawatts of solar power from the system. Conservation efforts during these times can prevent more desperate measures, such as rotating power outages, or generator equipment failures that can lead to more unplanned severe losses of power. CAISO recognizes that reducing energy use during the hot time of the day is a hardship, especially for those working and schooling at home. However, if a large number of consumers do their part in small ways, conservation can make a difference.

Between 3:00 PM to 10:00 PM, the CAISO is urging consumers to:

• Set air conditioning thermostats to 78 degrees, if health permits
• Defer use of major appliances
• Turn off unnecessary lights
• Unplug unused electrical devices
• Close blinds and drapes
• Use fans when possible
• Limit time the refrigerator door is open

Consumers can also take steps to prepare for the Flex Alert by doing the following before 3:00 PM:

• “Pre-cool” homes or lower air conditioning thermostats
• Charge electric vehicles
• Charge mobile devices and laptops
• Run dishwashers, washing machines, and other major appliances
• Set pool pumps to run in the morning or during the night

Remember, drink plenty of water and keep hydrated throughout the day. Thank you for doing your part to conserve energy during the Flex Alert.
