You may think of spring as the time for severe storms, but fall is a secondary season for tornadoes and other severe weather. AccuWeather's Anna Azallion explains why.

Meteorologists report that a secondary severe weather season occurs in the fall, in addition to the primary spring season. This increase in severe weather, including tornadoes, is primarily due to the clash of warm and cold air as the seasons change, creating favorable atmospheric conditions for storms.

Another contributing factor is the peak of hurricane season, which occurs around September. Landfalling hurricanes during this period often spawn tornadoes, further increasing the risk of severe weather. Historical data shows that years with more hurricane activity tend to have higher numbers of tornadoes. Forecasts indicate a moderate risk of severe weather in certain regions during the fall months.

Why is there a spike in severe weather in the fall?

Well, we could soon be seeing more scenes like what's on the right hand side of your screen because we're entering the second severe weather season now you might be thinking isn't that spring severe weather season? Well, that's. The primary season, however, we see another peak in tornado reports in the fall and others. Two reasons behind this one is very similar to why spring is our primary season. You have the clash of warm and cold air as the seasons are changing. That creates the right conditions for severe weather to spark. You need the right atmospheric conditions in order for tornadoes, severe thunderstorms to develop. The second reason behind this secondary season has to do with hurricane season, which actually peaks in September landfalling. Hurricanes often spawn tornadoes. Now you're seeing Hurricane Aaron on the right hand side of your screen. That was not a landfalling hurricane, so we didn't really have tornado reports. However, September 10th, that's the peak of our hurricane season, so that means we're likely to see a few more tornadoes. We're going to see a few more landslides, so that means we're likely to see things start to ramp up and any landfalling hurricanes that had our way. Well, we could see tornado reports. Let's take a look back at years past. Put things in perspective, right? So 2024 was kind of middle of the road, but had 178 hurricane spawned tornadoes. 2004 a very notable remarkable year. More than 300 tornadoes now specifically looking at last year and how we rank with other notable hurricanes. We have the last two on the left barrel and Milton, which spawned 46 to 68 hurricanes overall. So looking at what our long range team has put together as our forecast for September through November, where we're most likely to see this severe weather, it's the areas shaded on this map, especially in the orange. A moderate risk of seeing severe weather develop.
