-- At least 37 large wildfires are still raging across the United States, with no rain in the forecast this week.
A total of 128,000 acres has burned in the fire zone, which has spread from northern Georgia and eastern Tennessee into eastern Kentucky, the western Carolinas and parts of surrounding states. More than 5,000 firefighters and support personnel, as well as 24 helicopters, are working to contain the blazes, according to The Associated Press.
Smoke from the fires is causing significant air-quality and visibility issues in the region. Health officials across several states have issued air-quality alerts and advised residents to avoid outdoor activities.
There’s still no significant rainfall expected in the parched areas for the next seven days, according to ABC News senior meteorologist Max Golembo.
Some areas in Georgia have not seen rain for over a month.
North Carolina, Tennessee, and Kentucky have declared states of emergency.
Although a prolonged drought and warm winds are being blamed for the underlying conditions, authorities say some of the wildfires are man-made.
Tennessee officials said Tuesday that of about 1,238 wildfires that have scorched the state this year, almost 50 percent involve suspected cases of arson. At least seven people have been arrested in the past 22 days for arson in that state alone.
