Never mind that fall starts Friday.

It’s so warm in metro Atlanta that a code orange smog alert was issued, according to the Environmental Protection Agency.

The code orange designation means the air is expected to become unhealthy for sensitive groups, including those with asthma or other respiratory issues. Of the six categories on the Air Quality Scale, code orange is the third most severe, according to the EPA.

“Most of us (without respiratory issues) won’t be impacted,” Channel 2 Action News meteorologist Katie Walls said.

The code orange score ranges from 101 to 150.

Currently, the air quality is a moderate 80, the temperature is 82 degrees and the humidity is at 56 percent in Atlanta.

The average high for this time of year is 81.

The above-average temperatures are expected to last through next week.

There is a 30 percent chance of rain Friday, Channel 2 reported. However, “most of us will be nice and dry,” meteorologist Katie Walls said.

While things were calm locally, Hurricane Maria lingered just off the shore of the Dominican Republic with Category 3 strength and wind speeds of 115 mph, Channel 2 reported.

"Good" AQI is 0 to 50.  Air quality is considered satisfactory, and air pollution poses little or no risk.

"Moderate" AQI is 51 to 100. Air quality is acceptable. For some pollutants, there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.

"Unhealthy for Sensitive Groups" AQI is 101 to 150. Although the general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

"Unhealthy" AQI is 151 to 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.

"Very Unhealthy" is AQI is 201 to 300. This would trigger a health alert signifying that everyone may experience more serious health effects.

"Hazardous" AQI is greater than 300. This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.
