Dangerous heat for the LA Region is expected from Tuesday, August 25 to Friday, August 28.
An Extreme Heat Warning has been issued for the entire Los Angeles region, beginning Tuesday, August 25 at 10:00 AM through Friday, August 28 at 8:00 PM.
Forecasted temperatures are expected to reach 80-90 degrees along the coast, 100-110 degrees in valleys and lower mountains, and 90-100 degrees in Downtown LA and other interior areas.
In addition to the Extreme Heat Warning, NWS has issued a Red Flag Warning for the mountains and foothills bordering the northern portion of the City, including the Santa Susana and San Gabriel Mountains beginning Tuesday, August 25 at 10:00 AM through Friday, August 28, at 3:00 PM.
The mountains and foothills will see elevated fire weather conditions that favor fast moving fires and active fire behavior throughout the week. Those in the impacted area should be careful to avoid actions that could start a fire, and make sure they are ready to evacuate if a fire were to threaten their home.
During this heat event, it is important to be proactive from heat exposure. As temperatures rise, the City of Los Angeles urges Angelenos to plan and prepare to avoid heat exhaustion in your communities and for yourself. Call 311 to identify the cooling facilities closest to you, or visit the Cool Spots LA App.
Keep cool by identifying and resting in shade or a building with air conditioning and drinking plenty of water. If you do not live in an air-conditioned building, visit a public library, recreation facility, senior center or other public air-conditioned building near you. Drink plenty of fluids, stay indoors or in the shade, stay in a cool area, and check up on relatives and neighbors, especially if they have pre-existing health conditions. Check on neighbors or others who may be sensitive to heat. Never leave young children, the elderly, or pets unattended in vehicles under any circumstances, for any length of time.

See images below for an explanation of signs and symptoms. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the OSHA recommends frequent rest breaks in shaded or air conditioned environments and to stay hydrated. Employers must provide access to sufficient water. Anyone overcome by heat should be moved to a cool and shaded location. If you suspect a heat stroke, this is an emergency! Call 911. Non-emergency information can be found by calling 311.
