Thunderstorm



Thunderstorms are an uncommon event that occurs when wind speed reaches 20 mph and rain level is at 50%. They will continue until either wind speed drops to 15 mph or rain level drops to 40%. It is essentially a combination of the Rain and Windy Day events.

Storms will retain all of the same effects as the Rain event, including all rain enemies and initiating blizzards in the Snow biome. However, no enemies or special items from Windy Days will be present.

Occasionally, lightning will strike creating a flash of light on the screen, which is then followed by thunder. Wind picks up significantly when Thunderstorms are happening, causing leaves to fall at exceeding rates.

Music
These music tracks play while a  is ongoing. Like most other tracks, they can be recorded with Music Boxes. On the, when Otherworldly music is enabled, tracks from Terraria: Otherworld will play instead.

Trivia

 * On older Mobile Versions, similar lightning effects would be present when it rained. However, there was no sound of thunder.
