The Shelby County Health Department said there is โno single sourceโ responsible for odor concerns across the county and city of Memphis.
Health officials said the odor is believed to be the result of โtemporary weather conditionsโ including high humidity, fog, and high pressure. The department noted their meteorologists said these factors caused odors to linger โclose[r] to the groundโ for longer periods of time.
โThose weather conditions have changed, and the odors have dispersed,โ the Shelby County Health Department said in a statement.
The department said their team will continue to work with local officials to deal with possible sources.
Complaints about a smell permeating around Memphis surfaced over the weekend on social media. A Reddit thread with over 120 comments discussed the odor.
โIโve lived downtown for over 15 years and this smell happens every once in a while, but tonightโs smell is the [worst] Iโve ever experienced,โ one Redditor commented.
Netizens near Midtown also expressed concerns.
Chief Meteorologist at WREG Channel 3, Tyler Eliasen, took to social media on Tuesday and said while he couldnโt pin the source of the smell, the reason more people were aware of it was due to โtemperature inversion.โ
He explained that warmer air can exist โa few thousand feet above our headsโ during colder months, as opposed to cooler temperatures usually existing at that level.
โThis โinversionโ acts like a lid and traps pollution, smoke, dust, and yes, even smells near the ground,โ Eliasen said in a post.
The Shelby County Health Department said citizens experiencing โsimilar odorsโ should contact the Shelby County Mayorโs Action Center at 901-222-2300.
