Weather/California/Downey
Downey, California
City in Los Angeles County, California* WHAT...Temperatures up to 95 expected. * WHERE...Coastal areas of southwest California * WHEN...Until 8 PM PDT Saturday. * IMPACTS...Hot temperatures may cause heat illnesses.
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. In the event of a nearby wildfire, smoke may increase heat and physical stress. If smoke impacts your area; 1) Have a cooling plan in place as smoke could limit your ability to cool your home through open windows and 2) If you have air conditioning, set on air recirculation within the home to avoid smoke exposure. Local officials may have additional guidance.
