August 24, 2021 -  The US Interagency Wildland Fire Air Quality Response Program Smoke Outlook for the Caldor Fire for Tuesday.

Fire: The Caldor fire is now 117,704 acres, with 9% containment. Surface winds across the fire will again be from the SW with ridgetop gusts up to 20mph. Fire behavior is expected to be similar to yesterday with potential for spotting up to .5 mile.

Smoke: SW winds will continue again today. Winds and smoke transport will be dominated by terrain and diurnal patterns. Expect smoke to transport over the sierra crest to the E/NE during the day and drain back to the W/SW down the American and Cosumnes drainages in the evening/overnight. Those in Grass Valley, Placerville, and Auburn should see conditions improve to the Moderate level by 4:00 p.m., so consider planning your outdoor activities in the evening, before conditions degrade overnight. Those in the South Lake Tahoe can generally expect the lowest PM 2.5 concentrations in the early morning, before conditions worsen around noon as fire activity and smoke transport increases. Those in Tahoe City, Truckee, and Reno can expect a brief improvement, albeit into the Unhealthy range, in evening. Those in Carson City can also expect a brief improvement into the Unhealthy range around mid-day.

Health and Safety: Take it easier during smoky times to reduce how much smoke you inhale. If it looks or smells smoky outside, avoid strenuous activities such as mowing the lawn or going for a run. Reduce Your Exposure
