The "January 23, 1940 Southeastern Snowstorm" (often remembered as Atlanta's historic 1940 snowstorm or part of the broader "Great Snow of 1940" in the East) was a major winter event that delivered unusually heavy snowfall to the Southeast U.S., particularly Georgia, Alabama, the Carolinas, and extending northward along the East Coast. On January 23, 1940 (with snow continuing into the 24th in some areas), it blanketed parts of the Deep South in amounts that remain among the highest on record for many locations, paralyzing cities unprepared for such winter weather. The storm is iconic for Atlanta, where it set a benchmark for single-day snowfall, and it was followed by extreme cold that amplified impacts.
A coastal low-pressure system developed and intensified along the Southeast coast, tracking northeastward near Cape Hatteras before moving out to sea. This allowed moist air from the Atlantic and Gulf to overrun a deep, entrenched Arctic cold air mass that had settled into the region. The pattern produced heavy snow rather than rain in a wide swath from Alabama through Georgia and the Carolinas, with the heaviest bands focused across central/northern Georgia and extending into the Piedmont and parts of the Carolinas. Snow fell at rates up to 2 inches per hour in peak periods, accompanied by strong winds creating blizzard-like conditions farther north. The storm's southern track made it one of the most significant winter events to affect the Deep South in the 20th century.
The combination of heavy snow, strong winds (creating near-blizzard conditions), and extreme cold paralyzed coastal communities. Key impacts included:
Snow began falling on January 23, 1940, with the heaviest accumulations in a corridor from Alabama through Georgia and into the Carolinas and Virginia. Totals were exceptional for the region:
Many of these totals (especially Atlanta's 10.3 inches and Alabama's high marks) remain among the top historical snowfalls for those locations.
The storm was part of a historic cold wave. Following the snow, temperatures plunged dramatically: Atlanta saw record lows in the days after, and the state of Georgia recorded -17°F in Lafayette on January 25. In Alabama, Birmingham hit -10°F on January 26 and -8°F on January 27—one of the greatest cold waves on record for the state. Bitter sub-zero temperatures across the Southeast preserved snow cover and worsened impacts from frozen infrastructure.
Streets paralyzed in Atlanta (city nearly shut down); roads impassable, with drifts and ice; workers including 1,200 Fulton County jail inmates used to clear Atlanta streets; telegraph messengers delivered on skis; broader disruptions to rail, auto, and air travel; rural areas isolated (e.g., counties cut off from the outside world in NC).
Power issues from wind/snow weight; frozen pipes and water lines likely in the prolonged cold; overwhelmed services in urban areas.
Limited direct fatalities noted in sources, but exposure risks high in the cold; hardships for residents without modern snow removal.
Commerce halted; retail and daily business crippled in Atlanta and other cities; agriculture threatened by the freeze.
Schools, businesses closed; people stranded, with creative adaptations (e.g., skiing, mules for transport farther north); mail delivery limited; the unprepared South faced major challenges in recovery.
Bottom line: This storm holds a special place in Southeast winter history
