Still, as of Tuesday evening, the South Coast AQMD reported that Calabasas has 'good air quality," meaning they have an Air Quality Index below 50. Most of the city falls at a 41, a marked improvement from earlier in the day, when some parts of the city were above 50, signaling possible danger for sensitive groups.

Agoura Hills is averaging a 39, Malibu averages a 38, and most of the San Fernando Valley finds itself in the 40s. Earlier in the day, most of the Valley was placed in the "moderate" category.

To check levels near your home, click here, zoom in on the area of interest, and then click. AQI is determined by regulatory monitors, low-cost sensors, and an air quality model, according to the South Coast AQMD. The AQMD says that it uses the Environmental Protection Agency's NowCast method, which emphasizes recent levels when conditions are changing quickly.

The South Coast AQMD stresses that measurements are still approximate, and may not reflect current smoke conditions. If you smell smoke or see ash, remain indoors with windows and doors closed, or seek alternative housing. Limit vigorous physical activity, and clean air filters to make sure outdoor air isn't circulated in the home. See here for a full list of smoke safety suggestions from the AQMD.

Tuesday night going into Wednesday morning, west and south winds near the Palisades Fire are expected to push smoke north and east into the mountains in the Topanga State Park, and the cities east and north of the mountains, according to the AQMD.
