Heat Advisory Issued for Los Angeles County as Extreme Heat Watch Covers Southern California
A Heat Advisory is in effect for portions of Los Angeles County, including the Eastern San Fernando Valley, Western San Fernando Valley, Los Angeles County Inland Coast including Downtown Los Angeles, San Gabriel Valley, Santa Clarita Valley, and the Santa Susana Mountains. In addition, an Extreme Heat Watch has been issued for parts of Southern California as dangerously hot conditions are expected to intensify through the middle of the week.
Temperatures are forecast to climb well above seasonal averages, with inland valleys expected to experience highs ranging from the upper 90s to over 100 degrees. Downtown Los Angeles and inland coastal communities may see temperatures in the 80s and 90s, while the San Fernando and San Gabriel Valleys are likely to be among the hottest locations.
The prolonged heat will increase the risk of heat-related illnesses, especially for older adults, young children, outdoor workers, people without air conditioning, and pets. Warm overnight temperatures will provide little relief, making it harder for the body to recover from daytime heat exposure.
Residents are urged to drink plenty of water, limit strenuous outdoor activities during the hottest part of the day, wear lightweight clothing, and spend time in air-conditioned buildings whenever possible. Never leave children or pets inside parked vehicles, even for a short period, as temperatures can rise to life-threatening levels within minutes.
The combination of extreme heat and dry conditions may also elevate wildfire danger across Southern California. Anyone planning outdoor recreation should remain alert for changing fire conditions and follow any local restrictions.
Officials encourage everyone to monitor updated forecasts and any additional heat alerts, as the Extreme Heat Watch could be upgraded if confidence increases that dangerous temperatures will occur.
