Haze and Smoke Not Just From The Mesa

Fire management teams say that the smoke and haze you see across the Grand Valley during the day, isn't from the fires burning on the Mesa.

Most of the smoke in daytime hours has come from fires in northern California, and is not a result of the Clover or Coal Creek fires. But at night, light smoke in the Grand Junction area includes smoke from California and smoke from local fires.

While the haze has seemed rather intense, smoke levels in Grand Junction have remained well below federal air quality health thresholds. Firefighters are taking steps to reduce smoke production from the fires.

Smoke conditions are likely to improve over the next few days as seasonal monsoonal air flow develops. Smoke from California will likely be deflected farther north.
