Thunderstorm

Thunderstorms are an uncommon event that occurs when wind speed reaches 20 mph and rain level is at 50%, and continues until either wind speed drops to 15 mph or rain level drops to 40%. Storms will retain all of the same effects as the rain event, including all rain enemies and initiating blizzards in the Snow biome.

Occasionally, lightning will strike creating a flash of light on the screen, which is then followed thunder. Wind picks up significantly when Thunderstorms are happening. During a Thunderstorm, its exclusive music will play.
