Why does pink sky mean bad weather?
The Met Office has confirmed that these old adages are generally true, as it’s all to do with pressure systems that control the weather. A reddish colour in the morning comes from a high-pressure weather system moving to the east, ushering in a low-pressure system (which typically means rain).
What do pink clouds indicate?
Pink clouds floating from the west means they are taking away the moisture-laden clouds to somewhere else, while pink clouds in the east at sunrise indicates an approaching intense rainfall activity.

There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.
