Arizona is known for it's sunny skies and mild temperatures during the fall and winter making the state a popular vacation destination for many winter visitors as well as families looking to permanently relocate. But what most people don't know about Arizona during the winter is our High Pollution Advisories. Rainfall is responsible for helping knock out particulates and pollution in the air, however, it doesn't rain much here in the Valley of the Sun. Phoenix and the surrounding metro areas sit on the desert floor surrounded by mountains. This creates a bubble affect that can trap all those pollutants in our air that can't escape without the help of rain or wind.
During the winter it is common to have The Arizona Department of Environmental Quality (ADEQ) issue a health watch or what's better known around these parts as a "No Burn Day". These are days that the ADEQ says our air quality is unhealthy enough that you are not allowed by law to use any type of wood burning fireplace under penalty of a $250 fine. They will even advise individuals with respiratory problems remain indoors and suggest the general public limit their outoor activity as long as the high-pollution advisory is in effect. The Phoenix Metro area and Maricopa County will generally be issued a dozen or more No Burn Days each winter season.
