NWS Issues Extreme Heat Warning for Multiple Los Angeles Communities

Overview

• The National Weather Service’s warning runs from 8 a.m. on Sept. 9 to 8 p.m. on Sept. 10 and covers coastal and inland zones including Downtown Los Angeles, San Fernando Valley, San Gabriel Valley, Malibu Coast, Palos Verdes Hills, Calabasas and Agoura Hills.
• Forecast highs across the warned area are expected to range roughly from 88°F to 108°F with higher humidity that will make conditions feel hotter and increase discomfort.
• Officials say heat-related illnesses, including heat stroke, will rise during the event and urge people to drink fluids, stay in air-conditioned spaces, avoid the sun and call 911 for signs of heat stroke.
• The alert warns that car interiors can reach lethal temperatures in minutes and repeats OSHA guidance for outdoor workers to take frequent rest breaks in shade or air-conditioned areas.
• This local warning is part of a larger, season-long Southwest heat episode that has already stressed cooling resources, increased heat deaths elsewhere and raised concerns for utilities, wildfires and air quality.
