1977: Sioux Falls residents received a rude awakening during the morning hours as thunderstorms rolled through the city. Over two and one-half inches of rain fell in the city in an hour and 15 minutes. The large amount of rain in a short period of time led to street flooding in some areas. Lightning strikes from the storms also started several small fires.

1988: A tornado tracked a 25 mile path from Rietspruit to Bethesda, South Africa.

1989: "Princess", the Hurricane Hunter reconnaissance plane, was nearly lost when it went into the eye of Hurricane Hugo. It apparently hit a tornado-like vortex and lost two of its four engines. Fortunately the crew found a weaker spot in the eyewall and escaped.
