This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States in August, September and October 2024. Tornado counts are considered preliminary until final publication in the database of the National Centers for Environmental Information.

Similar to July, the northern states nearer the Canadian border are most favored for tornadoes in August, including the Upper Midwest, the Great Lakes, and the Northeastern states, due to the positioning of the summertime jet stream. In addition, there can also be occasional increases in the southern and eastern United States as a result of tornadoes from landfalling tropical cyclones should such occur. On average, there are 81 confirmed tornadoes in August. In September, tornadoes are most likely to occur in relation to the Atlantic hurricane season (as September is the peak month of hurricane season), and they can occur almost anywhere in the southern and eastern states as a result of landfalling tropical cyclones should such occur. A secondary focal point lies in the Midwest and Great Lakes as a result of early-autumn frontal systems. On average, there are 66 confirmed tornadoes in the United States in September. While tropical activity tends to decrease in October, the relative peak shifts into the Great Plains and towards the southern states as the jet stream shifts southward (albeit generally with less activity than in the spring months in the same regions). On average, 59 tornadoes are confirmed in October.

The late summer and early fall brought near average activity, with the tropics a primary focus. Similar to the previous month, activity during the beginning of the month was mainly due to the tropics as Hurricane Debby spawned 24 tornadoes. Simultaneous tornado activity also occurred in the Midwestern United States and Great Lakes region during that time. However, tornado activity then went dormant until the last few days of the month as non-tornadic severe storms became the norm. August ended with a near average amount of 87 confirmed tornadoes. September was quiet for the majority of the month until the last week, when Hurricane Helene produced an outbreak of almost 3 dozen tornadoes, one of which killed 2 people. September ended with a slightly above average amount of 76 tornadoes. October had a slightly below average amount of 53 tornadoes. Most were the result of Hurricane Milton that produced a prolific tornado outbreak in Florida, with 6 fatalities confirmed a result of the tornadoes. Another severe weather event happened on the last 2 days of the month producing multiple weak tornadoes.
