The National Weather Service said the most likely cause of the smoke is from a fire that started in southeast Georgia near the southern end of the Okefenokee National Wildlife Refuge.
This is the "West Mims Fire" and is currently still burning and will likely continue to burn for some time, the NWS said Sunday.
Winds in our area have sustained speeds of 10-20 mph, with gusts close to 25-30 mph. That would explain why the smoke is visible in our area, according to ABC11 Meteorologist Brittany Bell.
The smell of smoke is the area is suspected to come from the wildfires in the NC mountains. There are no fires locally.— Apex Police Dept. (@ApexPolice) April 16, 2017
Crews have searched the area and haven't found any active fires.
High pressure over the southeast has kept the smoke contained to the south and west of central North Carolina. Over the past day, though, the high has shifted east, allowing the smoke to be directed to our area.
Eyewitnesses said the smell of smoke was palpable Sunday afternoon, prompting many to take their concerns to social media.
