High ozone levels in Indiana could make it harder to breathe.

The Indiana Department of Environmental Management sent an Air Quality alert to the whole state.

They say the ground-level ozone, called smog, will be a real issue on Tuesday.

The poor air quality will continue as temperatures rise.

Officials say that elders, children, and those with medical conditions should not be too active.
