Decompressing the tornadoalley.bsu file will reveal some hidden developer-related comments left by Scott Bilas, a programmer and audio engineer at Loose Cannon Studios.

Originally, a news van and a storm chaser served the purpose of following the tornado around and alerting the people within area to seek shelter or evacuate from their homes entirely.

A Nintendo DS port of Tornado Outbreak, initially titled Tornado Alley DS, was in development from February to July 29, 2008 in collaboration with WayForward and Warner Bros. Interactive. Although this port was cancelled early on, it would suffer an identity crisis as its assets would be reused for the development of other projects. It first became an unreleased Looney Tunes game called "TAZ: The Disaster Master", before becoming the basis for a Crash Bandicoot prototype called "Crash Landed", until it was finally retooled into another Looney Tunes game that did see a release, Galactic Taz Ball.

An unused exit screen with the label "underconstruction_exit" exists within the game files. When activated in-game, the level will abruptly end and transition to the boss variation of the level's stage.

Unlike its Wii counterpart, characters such as Zephyr, Nimbus, and the Wind Warrior use two separate models in the Xbox 360 and PlayStation 3 ports of the game.

The first model is used during fly-through cinematics while the second one is used in-game. The Wii version only used one model, presumably because of the lack of resources on the Wii's hardware.

In most cases, the game's interactive music is comprised of seven different layers. The first layer, being the base melody, second being drums, third being bass, fourth being electric guitar, fifth being strings, sixth being woodwinds and brass instruments, and the seventh and final layer, a choir.

The sunlight in the Xbox 360 port of the game uses an animated shader that creates a mirage effect.

Enabling No-clipping mode in Chicken Con Carnage and heading back to the starting point of the map will reveal an unused spawn point for the L.O.A.D. STARR. Presumably, the level was intended to have two different zones.

An unused audio clip from the level Showdown with Omegaton suggests that Nimbus was originally going to tell Zephyr to pummel Omegaton's gigantic kidneys.

In numerous lines of the game's scripts, the vortex race is referred to as tpot. Player one, Zephyr is referred to as driver while player two, Wind Warrior is referred to as gunner.

A digital PlayStation 3 and WiiWare port of the game was in development, but was silently canceled. A digital version of the Xbox 360 port of the game, originally announced in June of 2009 as an Xbox Live Arcade title, was released on December 6, 2011.

Within the data for every version of the game is a semi-functional no-clipping mode that allows the player to freely explore maps without being stunned by the sunlight. The mode can be enabled by changing the value from "weatherphase1" to "weatherphase0". During exploring, the player won't be able to destroy objects that are within the sunlight.

A secondary no-clipping mode can be activated upon manipulating the level's "growmission" file. Unlike the previous method, players have full control of the camera but are unable to control Zephyr.

The Wii version of the game doesn't support widescreen. As a result, when the aspect ratio is set to widescreen, it will result in the display being stretched out.

The Stone Stomper has two unused pouncing animations that were intended to play during the Stone Stomp tutorial segment in Carnival Carnival. The first one, being a regular pouncing animation and the second one being a cannonball pounce.

The map Ringling Village features a statue of American writer Edgar Allan Poe. The crow standing on the statue is most likely a reference to The Raven, an 1845 poem written by Poe.

It is possible to grab and throw Nimbus with the tornado via modding. Since he doesn't have a death animation, his model will be stuck in an A-pose.

The ability to strip the clothing of certain humans was originally intended to be used for a side mission for Military Mayhem. The side mission in particular would've involved Zephyr pantsing the wandering soldiers in the first zone of the level.

Some of the tornado's sound effects were created by altering the sound effect of a tiger's roar.

As the game was originally intended to be a Wii exclusive, the colors for the tornado were colored coded after the colors of the Wii Remote's cursor. Player one, having a blue tornado while the second player having a red tornado.

The design for the fat horses in the Chicken Con Carnage stage is based on the horse Grane from the 1957 Merrie Melodies cartoon "What's Opera, Doc?"
