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.

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.

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?"

The location for Ringling Village is loosely based off of Wiltshire, a country from South West England.

The player can unlock an piece of concept art of what is assumed to be the inspiration for Tornado Outbreak; a poorly modeled tornado with a high polygonal model of a cow.

A sprite for the Wii Nunchuk exists within the game's files. The purpose of this sprite presumably relates to the cut Combo Moves mechanic, a mechanic in which players would've initially made use of the Wii Remote and Nunchuk combo to maximize their destructive potential. While Combo Moves were cut from the final game, motion controls would ultimately be reworked into Totem Battles.

Two early names considered for the game during development were Tornado Alley, and Zephyr: Rise of the Elementals. The game was first pitched to Warner Bros. Interactive under the Tornado Alley name in July 2006. These early design documents, alongside the documents for the unproduced Dirty Harry: Excessive Force, were later trademarked in 2008.

In both the regular and alternate ending to Showdown With Omegaton, a Wind Warrior can be seen holding his helmet.

Tornado Outbreak uses an in-house engine that incorporates a heavily modified version of RAD Game Tools' Granny 3D SDK. Unlike most video games that make use of the Granny 3D SDK, assets are compressed into one ZLIB archive that uses the .bgw extension. The core engine itself is written in C++, but also makes use of Lua scripting as well.

The Xbox 360 port of the game is the only version that natively supports 60 FPS. The framerate on actual Xbox 360 hardware is capped to 30 but can drop down to 9 FPS, because of the render distance and additional lighting. When emulated, the game maintains a steady 30/60 FPS depending on what's going on. Cutscenes, subtitles and loading screens move too quickly, and there is major slowdown when the game is running in 60 FPS. This is noticeable in the sixth level Ringling Village and the final level Showdown With Omegaton.

In 2009, audio engineer and programmer Scott Bilas released the Wwise project file for the game. While the project itself doesn't include the original .wav files, it's possible to reimport them within Wwise.

By swapping map files, it is possible to play the first two single-player exclusive levels in co-op mode. The first level, Roadside Destruction, plays like a regular co-op level while the second level, Chicken Con Carnage, requires player one to take control of the tornado while the second player grabs the Fire Flyers. This mechanic was eventually reused during the Vortex Race and Totem Battle segments after completing all zones.
