The term "chaser convergence" is a colloquialism for the phenomenon when multiple storm chasers from all over the world end up in the same place near a storm. True traffic problems from these "convergence" events are very rare, and the number of those who engage in egregious behavior is exceptionally small compared to the hundreds of chasers who regularly travel to the Great Plains. Unfortunately, some in the media and in official positions have chosen to publicly misrepresent the magnitude of these issues.
The purpose of this page is to provide factual information and evidence - not opinion - to counter these claims and inform the public, emergency management, law enforcement, government officials and media reporters. These pages have been prominently available online since 2015, and are well-indexed under the "storm chaser traffic" phrase. If you see a published article on storm chaser traffic that does not reference any of this information, you can be assured the writer either did not research the story, or chose to deliberately omit the information.

Storm chasers are constantly shooting pictures and videos during a chase. Consequently, we have video of everything that happens, often from multiple angles. Most severe weather events on the Great Plains are covered by many dozens of chasers. The result is a multitude of videos that plainly show the true state of the roads and behaviors of chasers. This section provides links to 63 uncut dash camera videos (some in time-lapse form) that show entire storm chases from beginning to end, including specific events mentioned in media coverage pieces and by officials.
A common item of anti-storm chaser propaganda seen in news articles and on social media is a map/radar combination image that plots the GPS location of chasers and spotters who beacon on the Spotter Network reporting platform. The dot icons on these maps used to represent chasers are astronomically large compared to the size of a vehicle. These dots are as much as a mile or more in diameter! Zoomed-out map views are often shared that deceptively create large congested masses of these dots, many with the intent to deliberately misrepresent the density of chaser vehicles on the roads.
On rare occasion, true traffic congestion can occur. And it's not just storm chasers who occupy the roads during these events! Tornadoes and supercells are spectacular wonders of nature that many local residents of the Great Plains also have a desire to see. This article outlines the factors that lead to increased numbers of vehicles around a storm - chasers and local residents alike - that can cause traffic issues, including statistics on the rare incidence of higher-end traffic congestion events.
