MEMPHIS, Tenn. — The high temperature reached 101 degrees Saturday in Memphis.

That breaks the old record of 100 set in 2012, the National Weather Service said.

The Memphis metro area is under a Code Orange Air Alert, the Shelby County Health Department announced Saturday afternoon.

Ozone levels mean air quality is unhealthy for the very young and old, and those with certain health conditions, the health department said. Those affected should limit outdoor exposure until after sunset.

Shelby, DeSoto and Crittenden counties are under the alert.
